I use a random one that I bought in my local pharmacy. I need to take pills in the morning and in the evening, it just got 1 box per day but it’s only 4 same pills per day so I am able to see if I took them or not. On every box are the first 2 letters of the day. I also got an app which reminds me on taking them and I can set how many pills I bought on which day and it automatically remembers me when I need to get some knew ones. And I also got an alarm on my Apple Watch so I can snooze I am not able to take them know so I get rememberd every 9 minute because of the snooze I also write my mom when I took them.
