Verdict
The clearest difference is review sentiment: B at 67% against Easy's 12%. B also leads on rating (4.3 vs 3.0) and ratings volume (57 vs 3). Easy's advantage is in-app purchases (none vs 7) and iOS requirement (14.0 vs 18.0). On price, update cadence, ads and device support 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. B sells 7 in-app purchases, starting at $0.99 per month. Easy asks for nothing beyond the download.
B holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: B has 57 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 12% of Easy's written reviews are positive against 67% of B's.
Both ship on a similar rhythm, roughly monthly. The most recent releases landed on August 30, 2026 and August 27, 2026 respectively.
