# TD Snap® vs Executive Functions

The clearest difference is price: TD Snap® at Free against Executive Functions's $1.99. TD Snap® also leads on update cadence (every 2 months vs every 13 months) and ratings volume (810 vs 1). Executive Functions's advantage is in-app purchases (none vs 10) and review sentiment (50% vs 30%). On ads and iOS requirement there is nothing between them.

TD Snap® is free to download; Executive Functions costs $1.99 up front. TD Snap® sells 10 in-app purchases, starting at $4.99 per month. Executive Functions asks for nothing beyond the download.

TD Snap® holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: TD Snap® has 810 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 30% of TD Snap®'s written reviews are positive against 50% of Executive Functions's, so the app with the better star average is not the one people write more warmly about.

TD Snap® ships an update every 2 months, Executive Functions every 13 months. The most recent releases landed on September 21, 2026 and September 12, 2026 respectively.
