License is linked to your Google account, so if you change phone, reinstall app, ... license will be kept. Just ensure correct Google account is used.
Do a phone reboot to force license refresh (or clear google play store services cache from phone settings).
License payment is ONE time only: lifetime license.
There are two licenses (you can buy only what you need, one only or both):
- PRO license: unlock everything except external app sync (Strava, ...). This license allow you see text notifications on your band, unlock widgets, setup custom calls, reminders, ... Ads will be removed.
- External sync license: unlock only external app sync (Strava, Runkeeper, ...) There is a free trial period of 24h.
Why not only one single license for all features? We want to keep app price lower as much possible, so we have created different licenses to allow user buy only what he needs
