OpenScan VS koler

Here's the GitHub for the project, and here it is on Google Play.

OpenScan

Needed to scan some receipts and found OpenScan. Does what it says on the tin, no bloat, no account needed, easy and quick to use, can save scans as an image file or as a PDF. No OCR, though. https://github.com/Ethereal-Developers-Inc/OpenScan

I've had good results with OpenScan, also available on the IzzyOnDroid f-droid repo.

Try open scan https://github.com/Ethereal-Developers-Inc/OpenScan

If you can't borrow a multi-function printer at school or somewhere, try using this or this app instead of just taking photos with your phone.

CamScanner, Office Lens: OpenScan will get you covered. Don't use the 155 MB spyware CamScanner.

plenty of mobile apps have the option to take a photo of sheet of paper and then crop the sheet of paper a rectangle

Alternatives: Connect You, Koler, QKSMS

Dialer: Simple Dialer (MD3) works fine. Koler (MD3) has a better UI, even than Google Dialer IMO, but it needs to have some bugs fixed and the notification runtime permission updated. Right Dialer (iOS-like/MD3) works fine too but I don't really like it; plus, I didn't compile the GitHub version, so, can't tell.

Hier is the link if somebody is interested: https://github.com/Chooloo/koler

Phone → Koler

You can request that by using Issues tab or make a pull request and implement that...

See https://github.com/Chooloo/koler/network. I don't know if any are "good", or even published though, just pointing out a feature of GitHub.

Google Phone → Koler

Add the 'phone dialler' catagory , I think the best is Koler link - https://github.com/Chooloo/koler or https://f-droid.org/packages/com.chooloo.www.koler/
