We just released the version on the App Store 3.1.4 from our app for iPads and iPhones / iPods touch.
This is a one-off update: we improved the appearance of the icons on the top bar of the app, corrected again an issue that caused titles to be cut off at the top and the app no ??longer closes unexpectedly when trying to save / share images.
Our special thanks go to Cassio Rossi for the collaborations made on our project on GitHub for this version 3.1.4. For those interested, the work to migrate it to the Swift language continues there! ?
