About

Stretch 20

Features
Read full description

Stretch · 20 is a focus timer that looks after your body while you work. Focus for twenty minutes, then take a one-minute guided stretch — right at your desk, no gym, no mat. Tiny breaks, big difference. HOW IT WORKS • Pick your rhythm: 20:20 for micro-breaks, 50:10 for longer recovery, or 90:20 for deep work. • Focus. A calm ring counts down your sprint, with a gentle word of encouragement along the way. • Stretch. When the break arrives, Dot walks you through one move: three simple steps and a line on why it helps. • Back to work, better than you left it. MOVES FOR THE WHOLE DESK DAY 33 free moves for eyes, neck and shoulders, wrists, torso, legs and circulation, breathing and hydration. A trainer-style rotation picks the right move for each break, and you choose which ones are in play. SEE THE HABIT GROW • Today at a glance: focus time, sessions, and a daily goal you set. • Streaks and weekly stats, with a best-day and a week-over-week trend. • A quiet daily recap when your active hours end. MADE TO FIT YOUR DAY • Live Activity: your timer on the Lock Screen and Dynamic Island. • Active hours, so it rests when you do. • Alerts your way: a chime, a screen flash, a torch pulse, or all three. • A calm dark mode when the light goes. PRIVATE BY DESIGN No account. No analytics. No tracking. Everything Stretch · 20 knows stays on your phone — the app never connects to anything except the App Store when you make a purchase. Delete the app and your data goes with it. PREMIUM, IF YOU WANT MORE Everything above is free, and stays free. Premium adds: • Four recovery packs — posture reset, desk athlete, calm & breathe, wrist & hand pro — 32 more moves. • Custom timing: any work length, any break length. • In-work nudges for water, posture and eyes, on your cadence. • Full history beyond the last 7 days. Monthly, yearly, or once for life. Nothing you already have is ever taken away. Made by Convora Labs LLP. Questions or ideas?
