"Where did I leave my AirPods?" "Is my Fitbit in the couch cushions... or lost for good?" Marco is the fastest way to find any Bluetooth device you've lost. Open the app, tap your device, and follow the live signal — it glows brighter as you get closer. No more tearing apart your house. No more giving up. --- WHY MARCO --- - Works with ANY Bluetooth device: AirPods, Fitbit, Garmin, Apple Watch, JBL speakers, Tile trackers, and more. - Live proximity orb pulses faster as you close in. - Warmer/colder direction hints tell you which way to move. - Haptic feedback guides you without looking at the screen. - Smart signal processing cuts through Bluetooth noise. --- SAVE YOUR DEVICES --- Bookmark any device and Marco remembers it. Saved devices sit at the top of your home screen — even when they're out of range — so re-finding is one tap away. With Marco+, the app watches for your saved devices in the background and notifies you the moment any of them comes back in range. --- RING YOUR DEVICE --- Tiles, fitness trackers, and many headphones can play a sound on command. Tap "Ring" and Marco makes your device beep through the couch cushions. --- LAST-SEEN ON A MAP --- Marco quietly records where you last saw each saved device. Open the map to see exactly where that was. Retrace your steps and find it. --- PRIVATE BY DEFAULT --- Nothing leaves your device. No accounts, no tracking, no data sold. Just your devices, found. --- MARCO+ --- Remove ads and unlock: - Background scanning with notifications - Unlimited saved devices - Last-seen map history - Battery level for compatible devices $0.99/month or $4.99/year. Cancel anytime in App Store subscriptions. Subscriptions auto-renew at the same price unless cancelled at least 24 hours before the end of the current period.
