You can now make your Aqua Mail Pro version purchase right in the app.Order processing is handled by Google Play, so it’s secure and convenient. Google will store your order under your device’s Gmail account.
With a new (additional) phone or after a reset to factory settings, when you re-install the free version of Aqua Mail, it will check for any existing In-App purchase and activate to Pro automaticaly.
This is only supported in the Google Play (as opposed to the “direct download”) version of Aqua Mail.
If you can use Google Play, we recommend making an In-App purchase directly from Aqua Mail’s “Upgrade to Pro” window.
Once you have the code, please enter it in Aqua Mail Settings -> Redeem code
