SplitsTree, PhyloSketch, CatReNet and PhyloParallelograms as native iOS apps
Where are my files? In the app’s own folder, listed in the files tab and visible in the Files app under On My iPhone or On My iPad. The apps save documents automatically shortly after each change.
How do I open a file from Mail, Files or another app? Use the share sheet and choose the app, or copy the file’s text and use Import > Paste into new file in the files tab.
How do I get an image or a result out? Use Export in the files tab or the export items of the document. They open the system share sheet, from which you can save to Files or Photos, send by Mail or AirDrop, or copy.
Can I use the same files on my computer? Yes. The apps read and write the same formats as the desktop programs, so a document can be moved back and forth through iCloud Drive or the Files app.
Is there an Android version? Not yet; Android versions are planned.
