I don't use a pill box but I do use a free app called medisafe. It sends me a reminder to take my morning meds at 8am and my evening meds at 8pm. After you take it you mark it as taken in the app, so if you forget if you took it you can look at the app and see. The app also has goodrx built in, so you can see if you could get your medicine for cheaper, and it also notifies you about drug interactions.

All in all, I recommend! here's the website
