If you have a feature request or want to report a problem with an application, please first “check for updates” to make sure you have the latest version of both the app and iOS/MacOS. If you’re still not satisfied, mail me at firstname.lastname@example.org.
Please use English and try to describe any issues or feature requests in detail. Include the name of the device you’re running the app on (iPhone 4, MacBook Pro 2010…) and anything you think might be relevant. I'll reply as soon as possible.
