Authors describe exercises that did not match the limitations they had stated. Saved exclusions and the ability to follow a prescribed plan are needed; the app should not confirm the safety of a load on its own.
Well-chosen exercises for older adults with live instructors and video, but intensity is too low even for the target audience, instructions are not synchronized with the trainer's movements, and the gender filter for coaches does not work as advertised.
評価点：Real live trainers instead of animated characters, at a pace that is comfortable for older adults.
不満点：Voice instructions lag behind on-screen movements, which is confusing during more complex exercises.
向いている人：Adults 60 and older who prioritize movement safety and a simple interface.
Muscle Booster covers a wide range of formats from strength to tai chi and chair workouts for older and low-mobility users. The home and gym sections were built by different teams without a shared standard: audio cues and weight recommendations are inconsistent between the two.
評価点：Chair workouts and tai chi for older users with limited mobility actually deliver results.
不満点：The home and gym sections operate by different rules: one has audio cues and the other has weight recommendations, and they do not overlap.
向いている人：Older adults and people with limited mobility who need adapted workout formats.
An app for the home rehab program prescribed by a physical therapist. The core problem is not the content but the mechanics: exercise timers consistently do not match what the specialist prescribed, and there is no simple way to log completion outside the app.
評価点：Video demonstrations help confirm correct technique when performing rehab exercises at home.
不満点：Exercise timers are not synchronized with therapist prescriptions: a 30-second hold becomes a 5-second timer on screen.
向いている人：Patients on a home rehabilitation program prescribed by a physical therapist.
The only app in its niche that tracks load and recommends recovery instead of pushing for records. The load algorithm can be overly conservative: it sometimes demands three rest days after a 30-minute walk, which erodes trust in its recommendations.
評価点：The philosophy of moving sustainably without burning out genuinely helps people build a lasting habit.
不満点：The load recommendation algorithm does not work correctly without Apple Watch and overestimates fatigue.
向いている人：Anyone who has burned out on fitness streaks and wants a gentle tracker without pressure to hit records.
Strong content from a real coaching duo with an extensive video library and no-equipment options, but the app is technically rough: freezes, TV streaming issues, and inaccurate timers frustrate regular users.
評価点：Live workouts from Coach Kozak and Claudia with form cues and modifications for different fitness levels.
不満点：Search and filtering are inconsistent, the no-equipment mode is not respected, and strength programs for older adults are nearly absent.
向いている人：Home workouts without a gym or personal trainer.
