Today, LightBlue is used by solo developers and engineering teams alike, including inside some of the world's most respected tech and device companies.

Lost your smart ring somewhere in the house? Smart Ring Finder finds it — free. Smart Ring Finder listens for your ring's Bluetooth signal and turns it into a simple hot-and-cold meter. Walk around and the screen warms up as you get closer — blue when you're far, red when the ring is within reach. Your phone buzzes faster the nearer you get, so you can find it without staring at the screen. Free, with no ads and no subscriptions. No GPS. No location tracking. No account. Nothing ever leaves your phone. HOW IT WORKS • Open the app and it locks onto your ring. • Walk slowly through the room. The color and the big label change from FREEZING to COLD, COOL, WARM, and HOT as you close in. • See an estimated distance and live signal strength. • Feel it: the haptic buzz speeds up the closer you get. • When it turns red, search low and inside things — pockets, cushions, drawers, bags. WHY IT'S DIFFERENT • Built for the way people actually search: a warmer/colder game, not a confusing map. • Tuned to the low-power Bluetooth signal a smart ring puts out. • Calm, clean design. Haptics let you hunt with the phone at your side. • Completely private and offline. FIRST TIME If your ring is connected to its companion app, close that app once so the ring can broadcast. Pick your ring, and Smart Ring Finder remembers it from then on. GOOD TO KNOW Smart Ring Finder finds the ring's general area using Bluetooth signal strength — it gets you to the right spot to search by hand. It can't work if the ring's battery is dead or it's out of Bluetooth range. Compatible with Oura Ring and other Bluetooth smart rings. Smart Ring Finder is an independent app and is not affiliated with, endorsed by, or sponsored by Oura Health Oy. "Oura" is used only to describe a device this app can help you find.
