Hot and cold, but make it nerdy
Findphone: Locate a nearby Bluetooth device by signal strength
A command-line phone hunter has commenters cheering, doubting, and making it weird
TLDR: A new Mac tool helps you track down a nearby missing Apple device by watching how strong its Bluetooth signal is, useful when Find My is blocked. Commenters were split between “finally!” and “will this even work if the phone is asleep?”, with side orders of Apple complaints and wildly unhinged jokes.
A tiny Mac tool called findphone promises to help you play hot-and-cold with a missing nearby Apple device when Apple’s own Find My isn’t available. In plain English: it watches Bluetooth signal strength and tells you if your phone is probably across the room, under the couch, or basically hiding in your laptop’s shadow. It can’t make the phone ring, can’t point like a compass, and it needs the device to still be close enough to whisper over Bluetooth. But for the right kind of panic? Commenters were instantly hooked.
The real drama, though, was in the reactions. One user said the whole thing was inspired by a huge earlier thread about losing a phone at the office, which gave this release a very “the internet manifested this” energy. Then the skeptics barged in: ruskyhacker basically questioned whether a lost phone would even be chatty enough to detect if it’s asleep, saying if the phone is lost, it’s probably “not super awake lol.” Ouch. Others went straight to why doesn’t Apple already do this for everything? after someone noted Apple has a similar trick for the Apple TV remote but not for your much-more-important phone.
And because no comment section can resist chaos, one poster immediately proposed turning it into a “pervert-glasses detector,” which is exactly the kind of cursed joke that hijacks a whole thread. Another took the nostalgic route, saying they’d wanted this 20 years ago so friends could find each other in clubs. So yes: one part practical utility, one part Apple side-eye, one part internet nonsense.
Key Points
- •Findphone is a macOS command-line tool for locating nearby Bluetooth devices by signal strength when Find My is unavailable.
- •It supports survey mode for nearby Apple handhelds, hunt mode for tracking one device by name, and a `--list` mode for paired devices and their addresses.
- •An optional `--sound` mode converts smoothed signal strength into faster clicks as the user gets closer to the target device.
- •The tool combines three signal sources: BLE GATT `readRSSI()`, BLE advertisements, and classic Bluetooth RSSI from `system_profiler SPBluetoothDataType`.
- •The article states that signal strength is only a coarse distance proxy, requires Bluetooth permission on macOS, and the tool cannot make a device ring or provide a bearing.
