Authors ask for a change of difficulty and for a break to be taken into account. What is needed is a repeat, a manual level choice and a saved history.
A large library of video workouts with live coaches, well suited for home training without equipment. Post-workout navigation and the absence of an exercise list before starting a video noticeably hurt the experience.
評価点：Wide selection of formats from 5 to 45 minutes with real coaches and a positive atmosphere.
不満点：No preview of exercises inside a video before it starts, which matters for people with physical limitations.
向いている人：Home workouts without equipment, especially for busy people and beginners.
A vast library of structured home programs (P90X, Insanity, 21 Day Fix) with live coaches and clear weekly progression. The content is proven and built to last years, but the technical side is rough: Chromecast is unstable and audio sometimes drifts from video.
評価点：Dozens of complete multi-week programs with well-designed progressive overload and professional coaches, making home training genuinely structured.
不満点：Casting to a TV via Chromecast is unreliable, and audio goes out of sync with video after updates without a fix on restart.
向いている人：Anyone who wants a structured home program without going to a gym.
Structured bodyweight programs for home use with a weight-loss forecast and plans by muscle group. Without any actual strength or load progress metrics, the app remains a collection of videos rather than a tool for tracking growth.
評価点：Equipment-free workouts get done without a gym visit and fit well into a daily routine.
不満点：No tracking of load or strength progress whatsoever, only a completion checkmark.
向いている人：Beginners with no equipment who need a ready-made home program.
Does its job well: video instructions, countdown timer, the ability to queue multiple sets in a row without extra steps. Ideal for short home workouts.
評価点：Start and train, nothing extra. Instructions are clear and multiple workouts can be queued up.
不満点：No Apple Watch support, custom workouts do not sync between devices, and the pause feature is awkward.
Clear timer-and-round mechanics for high-intensity seven-minute bodyweight workouts. The streak and achievement system works as a solid habit-building tool, but program variety is very limited.
評価点：The streak system and gamification genuinely help maintain consistency without an external coach.
不満点：No way to mark a missed day due to injury or illness without losing streak progress.
向いている人：People who want short equipment-free workouts and external motivation through gamification.
