# TouchChat Discover vs MN Executive Function Scale

The clearest difference is rating: TouchChat Discover at 3.7 against MN Executive Function Scale's 3.0. TouchChat Discover also leads on ratings volume (97 vs 2). MN Executive Function Scale's advantage is in-app purchases (none vs 11) and review sentiment (50% vs 22%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. TouchChat Discover sells 11 one-off in-app purchases. MN Executive Function Scale asks for nothing beyond the download.

TouchChat Discover holds the better App Store score, 3.7 against 3.0. That said, the two scores are not equally well evidenced: TouchChat Discover has 97 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 22% of TouchChat Discover's written reviews are positive against 50% of MN Executive Function Scale's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 11, 2026 and October 2, 2026 respectively.
