blep

Find your lost Bluetooth things — guided by feel. blep turns your phone into a warm/cold pointer that walks you right to it. The same scan runs in reverse to catch unwanted trackers following you — and points you to them too.

Calibrate

Hold the phone to your chest. Your body shields the signal from behind, making it directional.

Sweep & walk

Turn slowly until it’s warmest, then walk forward. The arrow and colour guide every step.

Pinpoint

Up close, kneel and search low. blep celebrates the moment you find it.

More than a finder

The same scan that finds your things also protects you from someone else's. All of it on-device — no account, no cloud, no ads.

🛡

Anti-tracking scan

Catches an AirTag, Tile or SmartTag travelling with you — then walks you right to it so you can remove it.

🔁

Sees through rotating IDs

Privacy trackers change their Bluetooth address constantly. blep recognises the same physical device anyway.

🌙

Watches in the background

Off, a battery-friendly timer, or a continuous watch — your choice, with a notification when something's off.

⌚

On your wrist

Companion apps for Wear OS & Apple Watch. On Android, phone and watch stay in sync — names, favourites, alerts.

🎒

Left-behind alerts

Tether your bag, keys or wallet and get a nudge the moment you walk away without them.

🔒

Private by design

No accounts, no analytics, no internet. Scans, sensors and history never leave your device.
