Never Lose What Matters
The eufy SmartTrack Link for Android (Black) is a compact, ultra-lightweight Bluetooth tracker designed to help Android users seamlessly keep tabs on everyday essentials like keys, bags, and luggage. Works natively with Google’s Find My Device network (and the eufy Security app), leveraging millions of Android devices worldwide for accurate location tracking without any subscription fees. It features an integrated keychain hole so it can be attached directly to your belongings without extra accessories, alongside a loud built-in buzzer that can be heard even through thick bags or cushions. Designed with convenient two-way functionality, double-tapping the tracker causes your phone to ring even when set to silent, while free left-behind alerts notify you before you accidentally walk away from your valuables. It is built with an IPX4 splash-resistant body, a scannable QR code on the back for finder contact details, and a replaceable CR2032 coin battery that lasts up to a year.
Key Features
Global Android Location Network
The SmartTrack Link leverages Android’s vast location ecosystem to help locate lost belongings beyond standard Bluetooth range. By securely tapping into millions of active Android devices worldwide, it provides accurate, privacy-encrypted location updates directly to your device.
Two-Way Phone Finder
A simple double-tap on the SmartTrack Link’s built-in button forces your connected smartphone to ring loudly. This works even if your phone is set to silent mode, helping you locate a misplaced phone instantly without needing someone else to call it.
Free Left-Behind Alerts
The eufy Security app monitors your proximity to the tracker and sends instant push notifications to your phone if you start walking away from your items. This proactive feature helps prevent loss before it happens, without requiring any paid subscription services.
Loud Built-In Alarm
Equipped with a high-decibel internal speaker, the SmartTrack Link triggers a distinct ringing sound when prompted through the app. The audio volume is clear enough to pinpoint items tucked under couch cushions, hidden inside thick backpacks, or placed in adjacent rooms.
Secure QR Code Recovery
The back of the tracker features an etched QR code linked to your chosen contact preferences. If a good Samaritan finds your lost item, scanning the code displays only the phone number or email address you choose to share, allowing them to contact you safely.

Is the battery rechargeable, and how long does it last?

Is the eufy SmartTrack Link waterproof?
It carries an IPX4 water-resistance rating, which protects it against rain, water splashes, and light spills. However, it should not be completely submerged underwater.
