Quite a basic part of the Ui. I’m using the M1 12.9” iPad Pro. Still give it 5 Stars, because plantUML is a great tool and this developer is building something very important that will encourage more geeks to document their designs. Pls fix that bug dude…

The program fails even on an example i copied out of their pdf description. In the error message it says its 108 days old and one should consider to upgrade. It also says it‘s a beta version. Seems as if the author „forgot“ to take it out of the appstore.

Does what it promises. Could use a screen mode containing both the editor and the preview at the same time.

I tried this app by iPad Pro 1st generation with iOS 16.7.2 though one review reports it doesn't work. And it works as expected! When a user report a negative information, he should report the device and the OS version he is using. And if the app is improved the star should also be updated. Then we can be a win-win relationship. Anyway, I'll use this app more. Thanks.

The Add Above/Below buttons don’t work for me which makes it a bit cumbersome to switch between the PlantUML keyboard and the regular keyboard to add a new line… If you can put up with this, the app generates the puml file and you can edit it elsewhere if you wish. It was not very expensive, however I find that the custom keyboard is not as useful as I was imagining. Further more, the app does not generate the diagrams unless you are online, so this makes it useless if you plan to use it while on the plane, for example. Most likely I will not use this app very often. Later Update: new version available, focused on AI. No usability changes. Using an external keyboard is very cumbersome (arrows don’t work for changing between lines - use Tab and Shift+Tab instead). Autosave does not work on pasted lines unless you change the pasted line. When autosaving, only the last registered change is saved (potentially last edited line), not the entire document. So if you paste a few line which are not manually edited, they will not be saved and you will loose some work. This also applies when attempting to render the UML diagram.
