OK app- ads in free are unreasonably long for the little number of calculations performed. Uninstalling and will use excel or google sheets.

Keeps crashing when I press solve. Edit. It does work if I set my phone to English (UK) instead of Swedish. Hope it helps.

Thank you for your feedback, Adrian. I will try to find the bug and fix it. Can you try to change your device language to english and see if the solve button works? Edit. Please update the app to the latest version , to see if the bug fixed.
