We are looking at our devices all the time. Put your tasks / todos / notes in the notification area and never forget them again.
microtasks is a plain simple todo/task/notes manager that uses entirely the notification area. Use it to add small things that you must do or remember during the day. Silent notifications are used to minimize disruption.
Tasks come "locked" by default for not swiping them away by mistake. When you are done, "unlock" and swipe to delete.
