Great tool - and I bought it
I used the free version for a while and needed the upgrade to store more history. The only thing I would add is the day of the week on the reminders page. Sometimes I dont open the app every day so I have a backlog of a few days. So it would be easier for me to remember if I took the pill on a certain day, rather than just he date.
I also use this to track my cats medication schedule.
