3. MyFitnessPal
MyFitnessPal is a powerhouse app for nutrition tracking and one of the most trainer-recommended tools for diet monitoring. It features an enormous food database and a barcode scanner, which allow clients to log their meals and track calories with ease. What sets MyFitnessPal apart is its use of AI-driven insights to help users make better dietary choices.
The app can analyze a person’s logged meals and provide personalized feedback or nudges – for example, alerting them if they are consistently low on protein or suggesting healthier food swaps. For personal trainers, having a client use MyFitnessPal means you can get reliable data on their calorie and macronutrient intake without requiring tedious manual food journaling. You can then review this data to inform your nutrition coaching and hold clients accountable. MyFitnessPal essentially serves as an AI-assisted food diary, and its ease of use makes it suitable for beginners who have never tracked nutrition before, as well as advanced athletes dialing in a cutting cut or bulk phase.
Another advantage of MyFitnessPal is how well it integrates with other fitness tech. The app connects with wearables like Fitbit, and with platforms like Apple Health, to automatically adjust calorie allowances based on activity or to share nutrition data with training apps. In fact, many coaching platforms (including Trainerize) sync with MyFitnessPal to import clients’ nutrition info directly. This integration capability means MyFitnessPal can serve as the nutrition hub in a trainer’s toolkit – all exercise and diet data come together for analysis. The core app is free, giving everyone access to calorie and macro tracking, while a premium version ($9.99/month) offers advanced features such as detailed nutrient analysis, food insights, and custom diet goals.
Key features of MyFitnessPal:

- Free with optional Premium: The basic app is free to use (sufficient for most clients), while premium unlocks deeper analysis, meal plans, and ad-free usage for those needing advanced features.
4. Gyroscope
Gyroscope is an AI-driven health app that gives personal trainers and their clients a 360-degree view of fitness and wellness. Unlike single-purpose apps, Gyroscope acts as a central dashboard for all health data: it syncs with wearables and fitness services to pull in information about workouts, steps, sleep, heart rate, nutrition, and even mood. By consolidating this data, Gyroscope provides a holistic picture of a client’s lifestyle and uses AI to generate actionable insights and coaching recommendations. For instance, Gyroscope can analyze patterns and might notice if a client’s recovery metrics (like sleep or heart rate variability) are down – prompting an automatic suggestion to incorporate more rest or adjust training intensity. It essentially serves as a background health coach, alerting both trainer and client to important trends that might affect fitness progress.
One of Gyroscope’s standout features is its integration capacity. It works with a wide range of popular devices and apps: Apple Watch, Fitbit, Oura Ring, Garmin, MyFitnessPal, and more all feed data into Gyroscope. The app then computes a “Health Score” and offers features like a Food AI (Food XRay) that lets clients log meals by snapping a photo for nutritional analysis.
For personal trainers, Gyroscope can be a powerful tool to support advanced coaching – you can monitor a client’s stress, nutrition, and activity levels in near real-time without manually collecting that info. Beginners benefit from seeing how different aspects of health interconnect (e.g., how better sleep improves gym performance), while advanced users love the deep analytics (weekly reports, correlations, and even AI-chat for health Q&A). Gyroscope is primarily mobile (with a strong iOS app), and it operates on a subscription model (with a premium tier for AI coaching features).
Key features of Gyroscope:
- Holistic data tracking: Aggregates data on workouts, nutrition, sleep, stress, and more into one dashboard for a complete health overview.
- AI-driven health insights: Analyzes biometric and lifestyle patterns to deliver personalized recommendations for improving sleep, diet, fitness, etc., much like a digital wellness coach.
- Broad wearable integration: Syncs with Apple Watch, Oura Ring, Garmin, Fitbit, WiFi scales, and other devices/apps to import metrics (HRV, steps, calories, blood glucose, etc.) automatically.
- Health Score & Food AI: Provides a simple Health Score to summarize wellness, and features like Food XRay use AI for quick meal logging and nutrition breakdown from photos.
- Detailed analytics & reports: Offers daily and weekly reports, trend analysis, and even an AI chat assistant for health questions, helping trainers and clients make data-driven adjustments to routines.
5. JEFIT
JEFIT is a long-standing workout planner and tracker that has incorporated AI elements to enhance strength training programming. It boasts a database of thousands of exercises and lets trainers or individuals create highly customizable workout routines. You can plan out workouts (sets, reps, weights, rest) and JEFIT will track each detail as the client logs their sessions. The app’s AI analytics come into play by reviewing the user’s progress over time and identifying plateaus or areas for improvement. JEFIT can analyze logged workouts and suggest adjustments – for example, if progress has stalled on a certain exercise, it might recommend a new rep scheme or alternative movement to keep the client advancing.
This adaptive routine feature helps both novice lifters, who may not know when to change things up, and experienced lifters, who want to optimize their training cycles. For personal trainers, JEFIT can serve as a collaborative tool: you can design a program, have the client follow and log it in JEFIT, and then both of you can review the stats and AI suggestions during check-ins.
The app provides rich visuals and analytics for tracking progress. JEFIT will graph a client’s lifting volume, one-rep max estimates, body measurements, and even muscle recovery status across workouts. These charts allow advanced trainers to fine-tune programs based on data (like adjusting volume if recovery is consistently low). Beginners using JEFIT benefit from features like exercise instructions and the ability to browse community-created routines if they need inspiration. JEFIT is available on iOS and Android, and also has a web interface, making it accessible on both mobile and desktop. There’s a free version with ads that offers core functionality, and a premium “Elite” subscription (about $6–7 per month) that unlocks advanced analytics, progressive overload reports, and removes ads.

- Custom workout planner: Allows creation of detailed workout routines with specific exercises, sets, reps, and rest, drawing from a vast exercise library (strength, cardio, machines, bodyweight, etc.)
- Workout tracking & logging – Logs every rep and weight lifted; provides real-time tracking during workouts and saves comprehensive logs for review, including personal records.
- AI progress analysis: Analyzes trends in the logged data to spot plateaus or recovery issues; can adapt and suggest routine changes to help users break through strength plateaus.
- Advanced analytics: Offers charts and metrics like 1RM progress, total volume over time, muscle group fatigue/recovery status, and workout frequency to train smarter.
- Cross-platform with community: Available on iOS, Android, and web, and includes community features (friend lists, routine sharing, leaderboards) – useful for motivation and for trainers to monitor multiple clients.
6. Tempo
Tempo is an AI-powered home gym system that brings the personal training experience into your living room. At its core, Tempo is a piece of smart fitness equipment – a screen with built-in 3D sensors and an accompanying set of weights – that uses artificial intelligence to guide and correct your workouts. For personal trainers, Tempo can be seen as an assistant coach that handles the on-the-spot form monitoring: as a client performs exercises, Tempo’s motion-capture technology detects their movements and provides real-time feedback to ensure proper form. For example, if a client’s squats are not deep enough or their back is rounding on deadlifts, the system will alert them immediately, helping prevent injury and improve technique. Tempo also creates personalized strength training plans, adjusting the recommended weight or number of reps based on the user’s performance and progress. As the client gets stronger, Tempo’s AI increases the difficulty to match, so the training stays challenging but safe.
This tool is particularly useful for both beginners (who need lots of form guidance) and advanced trainers (who want to ensure clients maintain form when training remotely). A personal trainer might use Tempo to remotely oversee a client’s workout: the trainer can trust that the machine will count reps and watch form, while they focus on higher-level coaching.
Tempo comes with a large touch screen that streams live and on-demand workout classes as well, effectively blending AI guidance with human-led instruction. It can integrate with heart rate monitors (the system often includes one) to display intensity and calorie burn, adding another layer of feedback. The platform is subscription-based for content – users buy the Tempo hardware (which is a substantial investment) and then pay a monthly membership for access to the class library and AI coaching features. The system is primarily used at home (there’s a mobile app for tracking progress, but you need the Tempo device for the full experience).
Key features of Tempo:
- 3D motion sensing & form correction: Uses a depth sensor camera to track your movements in real time and provides instant feedback on exercise form (e.g., spotting bad posture or incorrect technique).
- AI-adaptive workouts: Creates and adjusts personalized training plans, automatically increasing or decreasing weight and reps based on your performance and progression.
- Interactive coaching screen: Large display that shows your workout, your form (via a mirror-like video), and live or on-demand classes led by trainers, combining visual instruction with AI feedback.
- Performance tracking: Tracks reps, sets, weight lifted, and even muscle engagement, compiling data into charts and progress reports so you can see strength gains over time.
- Integrated hardware ecosystem: Comes with weight plates, dumbbells, or barbells that the system can “sense,” plus it pairs with heart rate monitors for training intensity – a comprehensive at-home setup for serious training.
7. lululemon Studio
lululemon Studio is an interactive fitness device that looks like a full-length mirror but doubles as a multimedia workout platform. It streams thousands of live and on-demand workout classes – ranging from yoga and pilates to boxing and strength training – right onto the mirror’s display, so users can see both the instructor and themselves (their reflection) at the same time.
While not as explicitly “AI” as some other tools, lululemon Studio does employ technology to personalize the fitness experience. It can use an integrated camera and AI technology to provide basic feedback and track metrics; for instance, it connects with a heart rate monitor to display your heart rate and calorie burn on-screen, adjusting the intensity recommendations accordingly. The device might also suggest classes or programs to you based on your workout history, which is a form of AI-driven personalization. For personal trainers, lululemon Studio opens up interesting possibilities: you can train clients remotely through the Mirror’s video call feature (seeing them exercise via the camera) or have them follow your recommended classes on their off-days.
lululemon Studio is suitable for all levels because of the variety of classes and the ability to scale workouts up or down in intensity. Beginners benefit from the convenience and the visual guidance – they can compare their form to the instructor’s side-by-side on the reflective surface. Advanced users enjoy the high-quality production classes and the diversity of workouts that keep training from getting stale. The cost includes a hefty one-time purchase for the hardware and a monthly subscription for the class content. Despite the cost, it appeals to tech-savvy clients who enjoy boutique fitness classes or those building a home gym with smart capabilities.
Top features of lululemon Studio:
- Immersive workout classes: Streams a wide variety of live and on-demand classes (cardio, strength, dance, etc.) with professional instructors, viewable on a life-size mirror display.
- Real-time performance metrics: Pairs with heart rate monitors and other sensors to show live workout stats (HR zone, calories burned) and can adjust or cue intensity based on that data.
- Sleek interactive design: Functions as a mirror when off, and as a screen when on – allowing users to watch their own form and alignment while following along with the trainer on screen.
- Personalization via AI: Uses algorithms to recommend classes/programs suited to the user’s goals and past workouts; the system’s camera and AI can detect motion for basic form tracking or rep counting (in certain programs).
- Remote training capability – Enables one-on-one personal training sessions by video, where a trainer can appear on the client’s device and vice versa, leveraging the built-in camera and two-way audio (bringing a live trainer virtually into the home).
8. Freeletics
Freeletics is an AI-driven fitness app known for its high-intensity workouts and bodyweight training plans. When a client starts Freeletics, they input their fitness level and goals, and the app’s “Coach” generates a training journey – this could be anything from a cardio-focused running plan to a strength-focused bodyweight circuit program. After each workout, Freeletics asks how it went (was it too hard, just right, or too easy) and uses that feedback, along with performance data (like completion time or reps achieved), to adjust future workouts. No two people’s plans are exactly alike because the AI is customizing the content and difficulty on the fly. For trainers, Freeletics can serve as an excellent supplemental tool: if you have an online client with limited equipment, you might have them use Freeletics on non-training days to get in effective bodyweight workouts that you can trust are scaled to their ability.
Freeletics covers a range of modalities – it started with bodyweight HIIT workouts but now also has running programs and even weights-based routines in some plans. The app also has optional mindset coaching and a nutrition app, making it a more holistic lifestyle coach if one opts in. The AI aspect ensures that beginners are not overwhelmed (the Coach will dial down intensity if the user struggles) and that advanced users are continually pushed (it ramps up difficulty as you improve). It essentially embodies the principle of progressive overload through AI.
Freeletics is available on mobile devices and is largely used anywhere since many workouts require no equipment (just a mat or space for running). The app operates on a freemium model: many features and some workouts are free, but the AI Coach personalization requires a subscription (often quite affordable, e.g., around $1–2 per week on annual plans). For a personal trainer, Freeletics can be a way to ensure clients stick to a regimen outside of sessions—because the app will motivate and challenge them—and it can provide additional data points (clients can share their Freeletics PBs and progress with you).
Top features of Freeletics:
- AI-personalized workouts : Generates custom HIIT and bodyweight training plans unique to each user, adjusting every workout based on the user’s feedback and performance.
- Adaptive difficulty: Continuously adapts intensity and exercises; as you get fitter (or if workouts are too hard), the AI Coach modifies routines so you’re always appropriately challenged.
- Versatile training modalities: Offers bodyweight circuits, running programs, and weighted workouts, allowing training anywhere – no gym required (great for at-home or travel workouts).
- Holistic approach: Includes optional mindset coaching (audio sessions for motivation and mental strength) and a Nutrition Coach app for diet plans, addressing more than just workouts in a fitness journey.
- Freemium access: The app has free workouts available to try, and the full AI Coach experience is unlocked via a paid subscription (with affordable plans), making advanced training guidance accessible without the cost of a human personal trainer.
9. Carbon Diet Coach
Carbon Diet Coach is an AI-powered nutrition coaching app that helps personal trainers manage client diets with precision and minimal effort. Developed by renowned nutrition coaches and scientists, Carbon acts like a virtual dietitian: users input their goals (lose fat, gain muscle, etc.) and log their food, and the app’s algorithm will set daily macro targets (protein, carbs, fats) for them. What makes Carbon intelligent is its weekly check-in system – each week, clients report their body weight and adherence, and the AI analyzes whether they are on track. If the client isn’t progressing as expected, Carbon automatically adjusts the nutrition plan, for example by reducing calories or modifying macros for the next week. This mirrors what a good human coach would do: assess progress and tweak the plan to keep things moving toward the goal.
For personal trainers, Carbon Diet Coach can be a game changer because it essentially handles the math and monitoring of diet plans. Instead of manually recalculating a client’s macros each week, a trainer can rely on Carbon’s AI adjustments and focus more on accountability and dietary behavior coaching.
The app itself has a clean interface that makes it easy for clients to log their food intake. It includes a barcode scanner and food database for tracking, much like MyFitnessPal, but with the coaching element layered on top. Clients also get feedback messages during their weekly check-in – e.g. “You lost 1 pound, so we’ll keep calories the same this week” or “No weight change, we’ll decrease carbs by 10g” – which helps educate them on how adjustments are made. Carbon supports different dietary preferences (like low-carb, plant-based, etc.) by allowing customization of macro ratios and has goals for things like reversing out of a diet (increasing calories gradually) or maintenance.
Carbon Diet Coach is a paid app (about $9–$10 per month, with slight discounts for longer subscriptions), but it’s far cheaper than hiring a full-time nutritionist. Trainers might either incorporate Carbon as part of their service (guiding clients through setup and monitoring their compliance via shared screenshots) or simply recommend it to self-directed clients.
Top features of Carbon Diet Coach:
- Automated macro adjustments: Every week, the AI evaluates progress and automatically updates calorie and macronutrient targets based on the client’s results (mimicking a live coach’s weekly check-in).
- Science-based algorithms: Developed by experienced nutrition coaches, it uses proven formulas to tailor plans for fat loss, muscle gain, or maintenance, adjusting for factors like metabolic adaptation.
- Comprehensive food tracking: Includes a food database and barcode scanner for easy logging, plus tracking of metrics like weight and compliance to feed the AI coach data.
- Goal-specific settings: Supports various goals and strategies (fat loss, muscle gain, reverse dieting, maintenance) and accommodates different dietary preferences (high carb vs. low carb, etc.), giving personalized recommendations.
- User-friendly feedback: Provides clear weekly feedback and guidance so clients know what changes are happening and why, effectively educating them; the interface is simple enough for beginners, yet the adjustments are precise enough for advanced users.
10. TrainAsONE
