# GroundZERO! vs Tappest

The clearest difference is review sentiment: GroundZERO! at 100% against Tappest's 44%. GroundZERO! also leads on ads (none vs shown) and update cadence (every 8 days vs every 3 months). Tappest's advantage is rating (4.0 vs 2.3) and in-app purchases (none vs 3). On price, ratings volume and device support there is nothing between them.

Both are free to download. GroundZERO! sells 3 one-off in-app purchases. Tappest asks for nothing beyond the download.

Tappest holds the better App Store score, 4.0 against 2.3. Both are backed by a comparable volume of ratings — 3 and 2 respectively. Written reviews complicate that: 100% of GroundZERO!'s written reviews are positive against 44% of Tappest's, so the app with the better star average is not the one people write more warmly about.

GroundZERO! ships an update every 8 days, Tappest every 3 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
