ReceptionRating · Positive reviews · Number of ratings

Keep It Mobile holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Keep It Mobile has 642 ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 57% of Keep It Mobile's written reviews are positive against 88% of SideNotes Mobile's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Keep It Mobile ships an update fortnightly, SideNotes Mobile monthly. The most recent releases landed on October 19, 2026 and October 16, 2026 respectively.
