It comes with an amazing app: The Radar Screen displays all of your devices within range.
You can tap the Sticker on the radar screen and decide if you would like it to buzz, flash the lights, or do both.
The radar screen can only be used to approximate the distance of the Stick-N-Find from your phone but not the exact directions.
Once you have located a Sticker you would like to find on your Radar Screen, you start walking in a specific direction, and see if you are getting closer or further from the blue dot on your Radar Screen.
Stick-N-Find Stickers have a range of about 100 feet, with a battery that lasts for over a year.
Uses a standard watch battery, so it is easy to replace.
Requirements: iOS devices with Bluetooth 4.0 or Android devices running Android 4.1 and newer.
It also has a buzzer and light, so that you can find your tagged items in the dark.
Sold in a set of two.
