Verdict
The clearest difference is review sentiment: UnderGuild at 79% against StoneAge's 31%. UnderGuild also leads on update cadence (every 2 weeks vs every 3 weeks) and iOS requirement (13.0 vs 15.0). StoneAge's advantage is rating (4.7 vs 4.5) and ratings volume (661 vs 79). On price, ads, 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. StoneAge sells 31 one-off in-app purchases and UnderGuild sells 19 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
StoneAge holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: StoneAge has 661 ratings behind it against 79, so its average is the more settled of the two. Written reviews complicate that: 31% of StoneAge's written reviews are positive against 79% of UnderGuild's, so the app with the better star average is not the one people write more warmly about.
StoneAge ships an update every 3 weeks, UnderGuild every 2 weeks. Both last shipped on October 28, 2026.
