Our goal with the free trial is to give you the opportunity to explore all the premium features the app has to offer.

During registration, starting the free trial allows us to ensure a smooth transition if you choose to continue with the subscription. 
Please note, that no charges will be made if you cancel the trial before it ends, which can easily be done through the App Store or Play Market.

After the trial period, if you decide not to subscribe, you’ll still have access to the app’s free limited version. However, we believe the premium version offers the best experience with enhanced features designed to meet a variety of needs. If you want to learn more about our Premium features, please, check out

If you already have an account and used trial before, you can re-install the app and use "Log in" option, instead of "Sync".
