Uh... I use a notebook that I bring and a calendar by my desk. I don't do well with apps and noise, paper suits me best. New day, new page, list your tasks and cross em off. (Added benefits: they can't steal your info if you don't insert your personal schedule hahaha! Not really, I'm just an internet addict.)

Yeah I'm too lazy to use calendar apps and stuff. Scheduling my day on Google Calendar felt wrong.

Procrastination tip: make everything easier and feelgood, you're more likely to use it. Also a tip for User Interface.
