About

Stretch Routines

Features
Read full description

Five minutes. Five to seven stretches. A body that stops feeling stuck. Cypress builds you a fresh guided stretch flow every day, then runs it for you on a calm 30-second timer. You never tap "next", never count, never guess what to do with your hips or your neck. Press start, breathe, move, done. Most stretching apps hand you a giant workout library and leave you to plan. Cypress does the planning. Each morning it sequences 5 to 7 movements from a curated set of 24 real stretches (Pigeon Pose, Hip Flexor Stretch, Thread the Needle, World's Greatest Stretch, Doorway Chest Opener and more), with a short rest between poses so you can settle into each one. The flow changes daily, so your whole body gets attention across the week instead of the same three moves forever. WHAT YOU GET • A different daily flow every day, so tight spots stop getting skipped • No tapping while you stretch: every pose holds for 30 seconds and advances on its own, with a rest breather between • Clear step-by-step cues, target muscles, difficulty and hold time for all 24 stretches • Search by name or muscle, filter by difficulty, and favourite the ones your body asks for • A one-tap single-stretch session from the library when only your neck or hamstrings need help • A streak counter, best-streak record, 7-day calendar and total minutes that turn a good intention into a habit PERFECT FOR • Desk workers whose shoulders, hips and lower back lock up by 3 pm • Runners and lifters who skip the cool-down because it takes too much thought • Anyone who wants more everyday flexibility without a 45-minute yoga class • People who want a quiet wind-down before bed that does not involve a screen full of stats WHY NOT JUST FOLLOW A VIDEO? A video needs your eyes on a screen, a stable internet connection and the same routine every time. Cypress runs on a timer with simple cues you can read once and then close your eyes. It works fully offline, it changes daily, and it takes exactly as long as it says it will. PRIVATE BY DEFAULT No account. No sign-up. No ads, no trackers, no analytics sent anywhere. Your sessions, streaks and favourites are stored on your iPhone and nowhere else. Delete the app and they are gone. FULL ACCESS Cypress is a subscription app. Choose the plan that fits: weekly, yearly, or a one-time lifetime purchase. Every plan unlocks the same complete experience: every daily flow, all 24 stretches, single-stretch sessions, and your full streak history. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled in your Apple ID settings. Payment is charged to your Apple ID account at confirmation of purchase. Download Cypress, press Start Flow, and give your body five calm minutes today.
