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.
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.
向いている人：Busy people who need short home workouts.
The classic seven-minute HIIT protocol works cleanly and requires no equipment. After the app redesign, custom programs degraded and navigating to the main workout became more steps than before.
評価点：Quick classic HIIT protocol without equipment, with Apple Health sync.
不満点：After the update, custom workouts stopped saving and were buried behind additional steps.
向いている人：People who need a short standard HIIT workout without configuration or extra steps.
A wide range of formats from stretching to cardio and strength, well suited for corporate wellness programs. Apple Health and Watch sync breaks, plan progress resets, and the exercise structure in individual workouts is weak.
評価点：Wide selection of short workouts across different types that fit easily into a work day.
不満点：No real progressive overload system or personalization to fitness level.
向いている人：Office workers who need short movement breaks as part of a corporate wellness program.
Simple home workouts by muscle group with a minimal interface work for maintaining basic fitness, but there is no program depth: no progression, no level adaptation, and no way to build custom routines.
評価点：A minimalist design and no extra screens let you start a workout in seconds.
不満点：No load progression: the app does not know whether things got easier and does not increase difficulty.
向いている人：People who need a quick home workout without any configuration.
