Great app!

Love the app, and the developer is very responsive. I email about an issue I had and they responded promptly and fixed the issue in the next update!

Developer Response ,

1. I'll add this in the next update. Thanks for the suggestion!
2. I considered adding alternate icons, but the icons really drove up the size of the app. Maybe in the future I'll revisit that.

Thank you so much for your feedback!

Hidden gem

Great little basic text editor. No big bulky features I don’t need. Opens and saves plain text files compatible with everything.

Best “hidden” feature, fully functional as a side-over app on my iPad. Need to jot down a quick note? Side it out, type, and slide it back. Perfect!
