Not Updated for Recent iOS Versions
Like your guitar app I just reviewed, it seems most of your apps have not been supported for a very long time. Have they been abandoned? It’s not fair to keep apps on the App Store that haven’t been updated in a long time. This one is free, but people may pay for apps and then find out that they are not functioning properly (if at all) because they don’t have current iOS certificates. It seems like your put a ton of work into your apps and that most people have loved them, so why not continue to keep them up to date and develop new features? I hope you’ll try to make sure the certificates are up to date ASAP and that your apps will start seeing regular updates again. Thanks so much!
