## Description

Have you ever walked out of a cafe, hopped out of a taxi, or left a friend&#39;s house only to realize your phone was left behind? Tracking apps help you find a lost phone, but Tetherd stops you from losing it in the first place.<br>By creating a secure, invisible Bluetooth link between your phone and a partner’s device, Tetherd acts as an invisible leash. The moment your devices move too far apart, an alarm sounds on both phones—giving you a vital window to turn around.<br><br>Key Features:<br>    • Preventative Alerts: Instant alarms sound on both paired devices if connection drops.<br>    • Smart Lock Security*: If an alert isn’t muted within your chosen time limit, your phone automatically locks to protect your private data.<br>    • On-Demand Proximity Radar*: Lost your buddy in a crowd? In a supermarket? Fire up the low-energy proximity screen to actively track how far away their phone is and home in on it, without draining your battery in the background.<br>    • Zero Internet Required: Works entirely via localized Bluetooth. Perfect for crowded music festivals, remote hikes, international travel, or daily commutes without using data.<br>    • Offline Messenger: Need to coordinate? Send quick, data-free text messages directly over the peer-to-peer Bluetooth connection.<br><br>* premium features unlocked by in-app purchase.<br><br>The app is available in these languages:<br> English<br> Spanish<br><br>For a fuller description, look here:<br>https://github.com/ceperman/tetherd/blob/main/README.md<br><br>For early installers, a limited number of promo codes are available on a first-come, first-served basis to unlock the premium features for free.
