12 app ideas that solve everyday problems

The most-loved apps solve a problem you have every single week. Think about what you do with sticky notes, kitchen timers and text messages to yourself — that is where these ideas come from. None of them need a big company behind them; most need one clear screen.

Prototype the one that would save you the most hassle, then share it with the people who share the problem.
