A reminder program for regular tasks on the phone or a record of vital activity?

Question

In life, I want to have time and most importantly - do not forget about a lot of things. But the life of a freelancer is so flexible and irregular that standard calendars don't quite fit. Of course, it’s better to do everything regularly, but a little knocking out of a tough schedule is not scary. The main thing is not to fall to zero. I would like such a reminder that would remind you of business and you could put a tick on it - did it and did not do it. And most importantly - graphs and / or a calendar for each activity - what is dynamic and what is not. This is very similar to the Endomondo type of training program. Things can be simple:
drink vitamins
every hour every hour get up stretch
once a week go for a massage
every other day to the gym
once a month write an article on Wikipedia.
Or maybe not deeds, but regular, but unplanned events: I
moved my grandmother across the road. Then look for a year how many grandmothers turned out.
or, as an option, health monitoring - how many times I sat at the computer so that my head ached.
