Verdict
The clearest difference is review sentiment: DRILL at 58% against Bold Attack's 19%. DRILL also leads on ratings volume (1.4K vs 418). Bold Attack's advantage is update cadence (daily vs fortnightly) and rating (4.6 vs 4.3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. DRILL sells 2 one-off in-app purchases and Bold Attack sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Bold Attack holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 1.4K and 418 respectively. Written reviews complicate that: 58% of DRILL's written reviews are positive against 19% of Bold Attack's, so the app with the better star average is not the one people write more warmly about.
DRILL ships an update fortnightly, Bold Attack daily. The most recent releases landed on October 13, 2026 and October 6, 2026 respectively.
