Needs to be updated

Nessun pulsante funziona con iPhone 6 (settings, log, addition, calibration etc)!
The Developer Website is dead, too.
If you guys dont want to give any support for new iOS versions, thats fine. But PLEASE INDICATE that the App is only working with outdated systems before people are buying it!!!
I call this a ripoff.
