Give me App ideas which will improve/solve daily life problems

Hi planning to create an app, lets give it a try

Note - 1. I'm a solo dev (so give me projects according to that) 2. The app should be offline and there should be no online stuff like fetching data or using an API 3. It should not be like to do list or note taking app because there are a lot in market with different varieties

Thank you, I hope I will not get downvoted and get answers because according to my experience if someone asks a question or help redditers immediately downvote in most of the sub 😅

Have a Nice day 😊
