Glacir shows you which muscles every stretch works, and builds your routine around what feels tight today. 80 STRETCHES, CLEARLY EXPLAINED Each stretch has its own illustration, short cues, what you should feel and where, and a "skip if" note. A muscles list shows what it lengthens, works or releases, with the Latin names one tap away. ROUTINES AND PROGRAMS • 21 ready-made routines, from a 2-minute reset to a long weekend session • 6 multi-day programs, such as Touch Your Toes and Front Splits in 30 Days, with a new day each day • Build your own routines • Tap where you feel tight on the body map, narrow it down to the muscle, and get a routine for the time you have A CALM PLAYER • Clear timer, both sides handled for you, gentle haptics • Short spoken announcements: the stretch's name, when to switch sides, when the routine is complete. A recorded voice in English, your iPhone's own voice in German, French, Spanish, Norwegian and Swedish • Live Activity on the Lock Screen • Optional Bluetooth heart-rate strap (Polar H10 and other straps with the standard Bluetooth heart rate profile): live heart rate during the routine, average and peak saved with the session LEARN FROM WHAT YOU DID • After each routine: the muscles you worked most, a quick "How did that feel?" and a suggestion for next time • Did a stretch pinch? Mark it. Glacir shows its skip-if note next time, and leaves it out of generated routines if it happens again • Muscle coverage for the last 7 and 30 days, your streak and your session history FITS INTO YOUR DAY • Apple Health: completed routines are saved as Flexibility workouts, wind-down routines as Mindful Minutes. Your recent workouts and steps help pick today's routine • Widgets for your streak and today's stretch, plus Siri and Shortcuts • A daily reminder, and an optional nudge after long periods of sitting • Four looks (Linen, Dusk, Mist, Ember) and the demonstrator you prefer: him, her or both • iCloud sync across your devices, without an account FREE AND PRIVATE Glacir is free, with no in-app purchases. No account, no ads, no tracking, no analytics. Your data stays on your device and in your own iCloud. Glacir is not a medical device and does not give medical advice. Stretch into mild tension, never into pain. If you have an injury or a medical condition, check with a professional first.

Verdict
The clearest difference is in-app purchases: Glacir at none against StretchPrep's 2. StretchPrep's advantage is iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.
