ReceptionRating · Positive reviews · Number of ratings

TD Snap® holds the better App Store score, 4.1 against 3.0. That said, the two scores are not equally well evidenced: TD Snap® has 877 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 31% of TD Snap®'s written reviews are positive against 100% of Colour Tiles by mathies's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. Both last shipped on November 6, 2026.
