### 2/5 — Don’t usefull

*2025-07-01*

I want an app like this ui for note book really great ui

**Developer response:** Hi! Glad to hear you like the overall concept at least! The app's primary purpose is to let users study and gain insight at moments of their choice, wherever they are – that's why it is fine-tuned for iPhone and iPad.
But we may have good news regarding your desire to use it on a laptop – the support for running this iOS app directly on a Mac is to be rolled out rather soon!
