Your physical therapist gave you a home exercise program. HealHabit keeps that plan organized: it reminds you at the times you choose, you tick off your sets and reps, and at the next visit you can show your physiotherapist what actually happened between appointments. WHAT YOU GET • Exercise checklist: enter each exercise with sets, reps, hold and rest times • A separate reminder for every daily session, at the hours that fit your day • Pain journal: one 0-10 entry per day, with a note if you want one • Completion streak and a monthly calendar showing which days you completed • Pain trend graph over 7, 30 or 90 days • Guided exercise timer that counts reps, holds and rest breaks for you • PDF progress report to hand to your physiotherapist • 22 languages, with light and dark themes NO CLINIC CODE NEEDED HealHabit works with the program from any physical therapist. Enter the exercises yourself, or use a template to prefill the form, then adjust every detail to match your instructions. MORE TOOLS FOR YOUR PLAN • 84 neutral exercise templates and detailed manual setup • Multiple programs with your own reference photos or short videos • Session feedback, weekly goals, and progress calculated on your device • Program sharing by QR code or portable file without an account or server • Optional spoken cues, a home screen widget, and Apple Health workout logging The free version includes one active program. Multiple programs are part of the one-time Premium purchase. PRICE Up to 3 exercises are free, with one reminder per exercise.

Verdict

The call

The clearest difference is ads: HealHabit at none against Flex's shown. HealHabit also leads on update cadence (every 3 days vs every 10 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
