Stretch Hollow
Read full descriptionHide full description
Stretch Hollow is a collection of guided stretching routines set inside a magical living garden. Each routine is a short, illustrated practice with its own plant. Choose a category. Pick how much time you have. Follow the guidance. Finish the routine. Watch the garden grow. HOW IT WORKS Open the garden and choose from eight plain-language categories: Morning, Desk Relief, Evening & Sleep, Full Body, Tension Relief, Warm Up, Strength & Balance, and Deep Stretch. Pick 1, 3, 5, 10, or 15 minutes and your routine begins. Every duration is a deliberately paced sequence designed to fit the time you chose, including guidance and transitions. Follow each illustrated pose as the timer counts down. Optional voice cues guide you without making you watch the screen. Tap the pose for step-by-step instructions, practical tips, comfortable variations, and things to watch for. Pause when you need to, restart a pose, or move ahead when you are ready. WHAT'S INSIDE • Guided routines across eight categories, from a gentle morning start or a quick desk break to full-body movement, balance practice, deeper stretching, and a quiet evening wind-down. • Five useful lengths for every category — 1, 3, 5, 10, and 15 minutes — with a distinct sequence created for each choice. • 198 illustrated exercises, with clear setup, movement guidance, practical tips, and cautions available in the session. • Optional spoken guidance, sound, and haptic feedback, each with its own controls. • A living, painted garden with 50 distinct plant species, changing light, and little residents who arrive as the Hollow comes to life. • An optional daily reminder at the exact time you choose. A GARDEN SHAPED BY YOUR PRACTICE Every standard routine is permanently connected to its own plant, and each Custom Routine slot has a plant of its own. Finish a routine and you tend that part of the garden. Return over time to help plants move from seed to full bloom. Practice different routines and the empty Hollow gradually fills with flowers, color, and life. CREATE YOUR OWN ROUTINES Build up to 10 custom routines from the complete 198-exercise library. Name a routine, search or filter the movement pool, add the exercises you want, arrange their order, and adjust each hold. Your exact sequence is saved on your device and can be resumed if a session is interrupted. UNLOCK THE FULL HOLLOW Stretch Hollow is free to download, with every Morning duration free forever. A single one-time Full Access purchase unlocks every duration in the other seven categories and all 10 Custom Routine slots. There is no subscription and no recurring charge. The price is shown in the app and may vary by region. • Payment is charged to your Apple Account at confirmation of purchase. • This is a one-time purchase — it does not renew. • Restore Purchases is available in Settings if you reinstall or switch devices. Stretch Hollow is intended for general wellness and is not medical advice.
