Lost your earbuds, watch, fitness tracker, tag or laptop somewhere nearby? If it is switched on, it is still calling out over Bluetooth. Foundy listens, lists every device around you and walks you to the one you are looking for. HOW IT WORKS • Open Foundy and every Bluetooth device in range appears within seconds, sorted by how close it is. • Pick your device. The Finder ring warms up, your phone pulses faster and the distance estimate shrinks as you get closer. When it says colder, turn around. • Tap Found it and Foundy remembers the spot where the signal was strongest. WHAT FOUNDY PRO INCLUDES • Live Finder with distance estimate, warmer/colder guidance, haptic and sound guidance and a signal history • Play a sound on devices that support Find Me alerts, or a loud tone through connected headphones and speakers • AI device identification: Foundy AI works out the likely brand and model from the signal details and tells you where such devices usually hide • Search coach: concrete next steps based on how the signal behaved during your search • Last-seen memory with the spot where the signal was strongest and a hand-off to Maps • My devices with in-range alerts while Foundy is open • Category filters, search and sorting for earbuds, headphones, speakers, watches, fitness bands, trackers, phones, laptops, tablets, keyboards, controllers, health and smart-home devices • Light and dark appearance, iPhone and iPad layouts, metres or feet GOOD TO KNOW Foundy hears devices that are powered on and within Bluetooth range, usually 10 to 30 metres indoors. Earbuds inside a closed case and devices with an empty battery stay silent. Distance is an estimate from signal strength, so walls and your body affect it. Foundy never uploads your location or your device list; AI features only send the technical signal details of the device you choose. Foundy Pro is an auto-renewing subscription (weekly or yearly). Payment is charged to your Apple ID account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Manage or cancel it in your App Store account settings.

Verdict

The call

The clearest difference is rating: Bluetooth BLE Device Finder at 4.4 against Foundy's 3.3. Bluetooth BLE Device Finder also leads on ratings volume (27K vs 4) and iOS requirement (13.0 vs 15.0). Foundy's advantage is update cadence (every 10 days vs every 2 months) and review sentiment (50% vs 39%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Bluetooth BLE Device Finder sells 4 in-app purchases, starting at $3.99 per 7 days and Foundy sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Bluetooth BLE Device Finder holds the better App Store score, 4.4 against 3.3. That said, the two scores are not equally well evidenced: Bluetooth BLE Device Finder has 27K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 39% of Bluetooth BLE Device Finder's written reviews are positive against 50% of Foundy's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Bluetooth BLE Device Finder ships an update every 2 months, Foundy every 10 days. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
