Verdict

The call

The clearest difference is review sentiment: Number Board at 80% against TD Snap®'s 31%. Number Board also leads on in-app purchases (none vs 4) and device support (3 vs 1). TD Snap®'s advantage is update cadence (every 2 months vs every 76 months) and rating (4.1 vs 3.8). On price, ads and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

TD Snap® holds the better App Store score, 4.1 against 3.8. That said, the two scores are not equally well evidenced: TD Snap® has 882 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 80% of Number Board's written reviews are positive against 31% of TD Snap®'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Number Board ships an update every 76 months, TD Snap® every 2 months. The most recent releases landed on November 6, 2026 and November 11, 2026 respectively.
