That gut-drop moment at the traffic light — "did I grab my wallet?" PocketCheck ends it. Photograph the things you can't leave without. PocketCheck cuts them out into stickers on your pocket board. Set a boundary around home — as tight as 20 metres — and the moment you step past it, your checklist appears. Tap through it and go. WHY IT'S DIFFERENT • Seconds, not minutes — GPS-confirmed departure alerts the moment iOS senses you moving, while other reminder apps wake up ten minutes too late • Your real stuff — photos become stickers, not another grey text list • Anywhere mode — leave a restaurant, gym, or friend's place after a real stay and PocketCheck checks you again. Smart rules mean brief stops never trigger and alerts never spam • Impossible to miss — Time Sensitive alerts break through Focus modes, with optional loud alarm sound and repeat-until-opened • Private by design — photos processed on-device, no accounts, no tracking, and your route is never stored HOW IT WORKS 1. Snap your stuff — wallet, keys, badge, anything 2. Drop your boundary on the map 3. Walk out the door — your checklist appears Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
