Do you want to purchase my app? I want to help you do that.
You pay for my apps using Google Play or Amazon. Please verify your payment method on Google Play or verify your payment method on Amazon, whichever applies. If that does not help, you may want to check the Google Play help pages on purchasing or the Amazon help pages on payment issues.
If you are unable to make the app store accept payment, you can directly purchase a license:
If the app does not unlock automatically, send a photo or screenshot of the app’s settings > help screen to [email protected] so I can assign your purchase.
Thank you.
