Leaving?

You're already out the door when it hits you — your keys are still on the counter. Leaving? is the quiet safety net that catches it: the moment you step out, it reminds you to grab the things you actually need. HOW IT WORKS • Draw a circle around a place — home, work, the gym, a friend's. • List what you shouldn't leave without: keys, wallet, wife, laptop, badge, gym bottle… anything. • When you leave, a notification names exactly those things. Different place, different list. THE MOMENT YOU LEAVE — NOT TEN MINUTES LATER Optionally use a place's Wi-Fi as the signal. The instant your phone drops off that network, you're reminded — usually before GPS even notices, and it works in a lift or basement where GPS can't. Prefer plain GPS? That works on its own too. SMART ENOUGH TO STAY QUIET If it looks like a GPS wobble — say you're still on your home Wi-Fi — it stays quiet instead of crying wolf. Every departure, and every time it chose to stay quiet, is logged in History, so you can always see it working and trust it. SEE WHICH WAY AND HOW FAR Realise you left something behind? While you're out, the status screen shows a compass pointing back toward your nearest place, with how far away it is and the direction to head. PRIVATE BY DESIGN No account. No sign-up. No servers. Nothing you type ever leaves your phone. It doesn't follow you or record where you go — it only watches the edges of the circles you drew, which is exactly why it barely touches your battery. Set it up once. Walk out with everything.
