I'll be taking the locator back to the store ### 1/5 — App Crashes when pairing *2015-09-20, version 1.3.0* Bought this item from Kmart - looked like a great product. I am using an iPhone 6 with iOS 9 on it, but also tried using iOS 8 on it. When I go to pair devices the app crashes - I have reinstalled the app, force quit the app and tried pretty much everything but the app just keeps crashing when pairing. Went into the store and tried another unit - the guy laugh and said cheap Chinese product and bad app. Please update and fix software glitch ### 5/5 — Like it very much *2015-09-07* Works very well ### 2/5 — Good concept *2015-08-25, version 1.3.0* The idea is good, if only there was a way to only turn the Bluetooth on when you need to find it. App has bugs and crashes. Needs more work ## Frequently asked questions about Rtrivr ### What devices does Rtrivr support?
