Need UI ideas and suggestions

Here’s my app:

https://play.google.com/store/apps/details?id=x.abcd

Quite a lot of my reviews say that the content is great but the UI sucks.
I’m not good with graphics, so what can I do to make the UI better?

I’m just using simple buttons and lists and home-made XML drawables, hardly any pictures or images…
The app is currently under an Mb, and I reckon I might be willing to take it up to 3-4 Mb for the UI.

Any suggestions or ideas as to how I can improve the UI would be much appreciated :slight_smile:

Hey man, I wouldn’t bother so much about these comments. I think the type of your app doesn’t require so much UI…
Some ideas:
use a better font for your text
use more neutral colors for background (light and dark greys)
use some better designed buttons with shadow on the most used screens
