Onus Workout

Onus records what you lift, tells you whether you are actually progressing, and puts you in touch with a real coach when you want to go further. YOUR SESSIONS, SET BY SET Start your session and log every set while you train: weight, reps, rest time. The timer starts on its own between sets. Your programme can be rearranged by hand, exercise by exercise, day by day. YOUR PROGRESS, WITHOUT THE FLATTERY Personal records, volume per muscle group, curves per exercise. You see exactly where you are gaining and where you have stalled, on data you entered yourself. YOUR NUTRITION Food diary, meal scan, weekly menus and a shopping list built from what you actually eat. Your calorie targets follow your goal, whether you are bulking or losing weight. YOUR BODY Measurements, weight, progress photos lined up side by side, a soreness map on an anatomical chart. Onus also reads your Apple Health data (sleep, resting heart rate, energy) to place your sessions in your real recovery. A COACH, A REAL ONE Pick a coach listed on Onus. They write to you, build your programme, set your nutrition and follow your sessions week after week. Nothing is automatic: it is a person answering you. THE COMMUNITY Share your sessions, comment on other people's. Every post, every comment and every private message is filtered before it is sent; you can report and block anyone in two taps. ON YOUR WATCH Onus comes with you on your wrist: validate your sets and start your rest timers without taking out your phone. ONUS PRO Onus Pro subscription: $9.99 per month, or $59.99 per year (two months free). It unlocks the AI coach and advanced statistics, and removes advertising. Automatically renews unless cancelled at least 24 hours before the end of the current period; manage and cancel it in your App Store account settings. Terms of Use: https://onus.fr/cgu.html Privacy Policy: https://onus.fr/confidentialite.html Onus is not a medical device and does not replace professional advice.

The clearest difference is update cadence: Kaizmax at daily against Onus Workout's every 4 days. Kaizmax also leads on device support (4 vs 2) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
