Verdict
The clearest difference is rating: Wind Up Robots at 4.8 against Pass and Boum's 4.1. Wind Up Robots also leads on ads (none vs shown) and iOS requirement (11.0 vs 15.0). Pass and Boum's advantage is review sentiment (60% vs 34%) and ratings volume (275 vs 6). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Wind Up Robots sells 4 one-off in-app purchases and Pass and Boum sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Wind Up Robots holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Pass and Boum has 275 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 34% of Wind Up Robots's written reviews are positive against 60% of Pass and Boum's, so the app with the better star average is not the one people write more warmly about.
Wind Up Robots ships an update every 5 weeks, Pass and Boum every 3 weeks. The most recent releases landed on October 20, 2026 and October 27, 2026 respectively.
