LEIS App
LEIS ("Life Is A Symbol") is the companion app for a connected bracelet whose colour signals the wearer’s relationship status. The app pairs with the bracelet over Bluetooth, controls its LED colour and brightness, monitors battery, and runs a credit wallet: each status change spends one credit, with credit packs purchased in-app.
