Boop

See a nearby person. Pop their bubble. They get Booped. Boop is a small, local-only native Android app. Translucent animated soap bubbles drift in a calm little field. Decorative bubbles pop only on your own phone; named bubbles represent real nearby people who opted in. Tap a person’s bubble to send a direct Bluetooth Low Energy Boop. Their phone posts a small notification, and they can reply with one of five emoji before meeting in person. • Procedural iridescent bubbles: grab, fling or stir empty space, with film-petal pops and quiet synthesized contacts. • A name and accent color, without profiles, accounts or a friend list. • Basic foreground discovery; optional Background Boops and Floating Boops are off by default. • Contextual Bluetooth/notification permissions; overlays require a separate explicit choice. • No Internet permission, trackers, analytics, ads, cloud, Google Play Services or proprietary backend. • Open documented Boop BLE Protocol v1; no pairing or bonding. • System/light/dark themes, accessible named bubbles and continuous motion independent of Android UI animation settings. Android 12+ and BLE advertising support required. Background discovery requires Android’s persistent service notification and can be interrupted by battery restrictions or force-stop. Floating bubbles never read another app or appear on the lock screen. Nearby names and identifiers are public radio information; messages are not encrypted or authenticated. This is a playful social Boop, not secure messaging.
