Very cool concept! I wanted to make a similar thing a few years ago, but for a slightly different purpose: force myself to walk more. I built an iOS app called Geostreaks [1] with a simple mechanic: pick an outdoor location (for example, a nearby park) and “check in” there every day. I couldn’t justify the yearly developer fee though, so the app has been removed from the App Store a few years later :( 1. https://appadvice.com/app/geostreaks/1482655198 https://appadvice.com/app/geostreaks/1482655198
