Fix Restore Purchases
Great app with poor, sub-standard maintenance. I want the sound to work on Iphone SE. Furthermore, I re-downloaded the app and it won't restore my purchase.Matttop
Payment
I would like to pay for the application but I can’t pay for the subscription fee. Is there something wrong on my end or is there an error in the app. Thanks!Jowin91
Good ap
Good way to quickly review some characters. Short lessons are a plus for a person who wants to run a short batch in a limited amount of time. I’ve used this ap on and off for years.Fiddle time
