Supreme
Just type whatever you need to do, drag and drop to reschedule, and set alerts by simply typing the time – all information is contained in good old plain text. Ease of use and the lack of cruft is what makes supreme, quite possibly, the most productive todo list ever. Just scroll through your agenda to see the great things you've done in the past or plan far into the future. Oh, and if you didn't complete something today, Supreme will automatically bump it forward tomorrow. Awesome, right?
