ReceptionRating · Positive reviews · Number of ratings

PillCalendar holds the better App Store score, 4.3 against 1.8. That said, the two scores are not equally well evidenced: PillCalendar has 187 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 18% of ePEF's written reviews are positive against 17% of PillCalendar's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ePEF ships an update every 6 weeks, PillCalendar every 2 months. The most recent releases landed on September 17, 2026 and September 24, 2026 respectively.
