Count as far as you can, as fast as you can, while avoiding numbers that are evenly divisible by 7 and numbers that include the digit 7.

Verdict
The clearest difference is review sentiment: Impossible 7! at 63% against Rock Pusher's 25%. Impossible 7! also leads on in-app purchases (none vs 16) and ads (none vs shown). Rock Pusher's advantage is update cadence (weekly vs every 63 months) and rating (4.5 vs 4.1). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Rock Pusher sells 16 one-off in-app purchases. Impossible 7! asks for nothing beyond the download.
Rock Pusher holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Rock Pusher has 10K ratings behind it against 48, so its average is the more settled of the two. Written reviews complicate that: 63% of Impossible 7!'s written reviews are positive against 25% of Rock Pusher's, so the app with the better star average is not the one people write more warmly about.
Impossible 7! ships an update every 63 months, Rock Pusher weekly. The most recent releases landed on September 23, 2026 and September 30, 2026 respectively.
