This app is trash. The tracker might work but you have no idea becose notifications, setting and simply an app itself just not working. The premium subscription doesn't fix anything 😅 Useful only if you need to track something once a day or once a month. I tried to set update every 5 min from 800 until 1200...Im quite sure tracker is not where map is showing tracker now.

After 3 months of use, it doesn't work. Very good 6 years warranty. Battery is full but doesn't emit.

It works fine at first. However, the battery lasts less than a year, even when set to update only once per day. Charging CHF 30 for a battery replacement plus CHF 15 for shipping feels like a rip-off. My device is: Gemstone Bike GPS Tracker.

The app works fine. I give 2 stars, because Gemstone, doesn't. For more than a year it constantly keeps showing - "poor reception" and there is no connection with it, no matter whether it's in a bike, in my pocket, next to the WiFi router, in a car, under a large sunroof... in the city, on a highway, in the forest. It just doesn't like to connect to the GSM net, or it does it sporadically, incidentally and very rare. Even during the premium plan, when it's supposed to use Wifi-s it was the same

It's ok but I have found 2 annoyances: the app never opens when I tap on the notifications. It just shows a black screen. If I kill it and start it manually then it starts. Then, it's not clear from the app what you are getting if you upgrade to the paid plan. Happy to revisit this rating if it gets fixed (especially the notification problem). Edit: the very last version introduces another problem, the 3-buttons menu now overlays over the app, so certain things are much more difficult to tap.

Had to buy 2 of the trackers as the first 1 fell off despite there so called clam of extra strong advice tap. The second 1 how now stopped working will not update and last updated about 1 month ago show its it a completely different place the where the tracker is. Not happy seeing as if have paid for premium service

Yderst upræciset. Ofte et sted mellem 50 og 100 m off. App sender sjældent notifikationer om placering. Af et DK produkt og til prisen kan jeg kun erklære mig meget skuffet og vil ALDRIG anbefale til andre. Skuffende, skuffende & SKUFFENDE eller måske bare defekt...?

App have cleared my account for some reason (that they didn't care to tell me about) Nice if you buy a thing and the seller just kill it
