Verdict
The clearest difference is rating: Lost Mastery at 4.3 against Roia's 3.5. Lost Mastery also leads on update cadence (every 5 days vs every 10 days). Roia's advantage is chart position (#182 vs unranked) and ratings volume (24 vs 4). 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
Roia costs $2.99 and Lost Mastery $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Lost Mastery holds the better App Store score, 4.3 against 3.5. That said, the two scores are not equally well evidenced: Roia has 24 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 60% of Roia's written reviews are positive against 50% of Lost Mastery's, so the app with the better star average is not the one people write more warmly about.
Roia ships an update every 10 days, Lost Mastery every 5 days. The most recent releases landed on October 13, 2026 and October 17, 2026 respectively.
