Your device is part of the compatible Android devices.
Still, you can't download the Wistiki app because :
-Searching "Wistiki" in the Store does not lead to anything relevant
-The Play Store states that your device is incompatible.
Don't worry, your device is indeed compatible with the Wistiki technology !
Our teams of developers are currently working on improving and optimizing the application on these devices so that you can live the best possible experience from your very first use of your tiny Wistikis.
Here is the update calendar :
-Compatible Apple products and Samsung smartphones can already use the Wistiki app.
-The updates for Nexus and HTC Smartphones will take place on January 10, 2015
-The updates for Xperia and LG Smartphones will take place on January 20, 2015
-The updates for compatible Android tablets and compatible Wiko devices will take place on January 31, 2015.
A few days of waiting, and never lose your belongings again !
