FormCheck Plus vs 4Level

FormCheck Plus is your AI-powered form coach for confident, effective home workouts. Record one clean rep, tap the toughest moment, and get instant, specific feedback on your form — what's working, what to fix, and how to move better. No timing a shutter mid-rep, and no guessing whether you're doing an exercise right. WHAT YOU GET - AI Form Check: record a rep, pick the hardest frame, and get a Form Score, a joint-by-joint breakdown, plain-language fault flags, and next-rep corrections. - Guided exercise library with setup cues, common mistakes, and back-friendly swaps. - Workout plans plus a session log that tracks your training load and consistency. - Daily readiness check-ins and progress trends so you can train smarter. - A guided back-care routine built around gentle, well-established movements. YOUR CLIPS STAY ON YOUR DEVICE Recording is optional, and access to the camera or your photo library is only ever requested at the moment you choose it. Clips are never uploaded or stored. Only the single frame you pick is sent to our AI service for analysis — and only after you agree in the app — and it is discarded once your report comes back. FORMCHECK PLUS PRO (optional subscription) Unlock unlimited AI form checks, comfort-pattern insights, and a weekly coach summary. - Monthly ($9.99) or annual ($79.99), with a 7-day free trial - Payment is charged to your Apple ID at confirmation - Auto-renews unless canceled at least 24 hours before the end of the period - Manage or cancel anytime in your App Store account settings FormCheck Plus offers general fitness and form guidance and is not a substitute for professional medical advice.

4Level is made for ambitious amateur athletes who already train regularly and want to know: How fit am I really — and am I sticking to what I set out to do? WHAT 4LEVEL IS — AND WHAT IT IS NOT 4Level analyses the workouts you already record. It does not create training plans, workouts or coaching advice and does not replace a coach. You decide how you train; 4Level measures, explains and keeps you honest. YOUR LEVEL, 1 TO 100 One number from three building blocks: • Fitness — your training load of the last six weeks (CTL) • Capacity — running VO₂max (VDOT) or cycling watts per kilo • Consistency — how regularly you train and, once you set your resolutions, how faithfully you keep them Calculated for every single day back to your first workout, using only what was known on that day. Every value shows whether it was measured or estimated; the whole formula is explained in the app. STICK TO YOUR RESOLUTIONS Set per sport — running, cycling, hiking, swimming, strength — how often and on which days you intend to train, or train as you feel like it. Add weekly, monthly or yearly kilometre targets if you like (not for strength). 4Level shows whether you are ahead or behind right now, a 26-week heatmap, your streak in weeks and your month balance. Flexible by design: ran Monday, Tuesday and Saturday instead of Monday, Wednesday and Friday? The week still counts. Measured retroactively for the last 26 weeks if you want. LOAD, FATIGUE AND FRESHNESS Fitness, fatigue and freshness (CTL, ATL, TSB) show whether you are rested, building or overloaded — judged on the trend of the last days, not on how tired you are right after a session. Race predictions for 5 km to marathon come from your runs of the last 120 days: pace and, if you record it, heart rate. RECOVERY After each session dots fill the gap at the bottom of your level ring; when the ring closes, you are recovered. How long that takes depends on the load and intensity of the session and on your fitness. 4Level also reads resting heart rate, heart rate over the day, HRV and cardio recovery, analyses your history once and adapts the recovery time to how you actually recover — Apple Watch or another device that writes heart rate to Apple Health. A notification when you are recovered is optional. RUNNING, CYCLING AND HIKING Yearly goals with a marker where you should be today, this year against last year and your best year, weekly volume, records, all years at a glance. Plus a searchable list of all your workouts. WORKS WITH THE APPS YOU USE 4Level reads from Apple Health — everything your Apple Watch, Garmin Connect, Strava, Zwift, Wahoo and other apps write there. You choose per sport which app's recording counts; the same session recorded twice counts once, and missing heart rate, climbing or power is filled in from the other recording. PRIVATE BY DESIGN No account, no server, no analytics, no ads. Data is read from Apple Health and stays on your device. PRICING 30 days free with everything included. Afterwards 4Level Pro: a yearly subscription (renews automatically, cancel anytime in your Apple Account settings) or a one-time lifetime licence.
