Verdict
The clearest difference is rating: E/M Coder at 4.0 against maxCoder's 3.0. E/M Coder also leads on update cadence (every 2 weeks vs every 5 months) and ratings volume (8 vs 1). maxCoder's advantage is review sentiment (33% vs 25%) and iOS requirement (7.1 vs 9.0). 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. Neither carries in-app purchases, so what you see is what you pay.
E/M Coder holds the better App Store score, 4.0 against 3.0. That said, the two scores are not equally well evidenced: E/M Coder has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of maxCoder's written reviews are positive against 25% of E/M Coder's, so the app with the better star average is not the one people write more warmly about.
maxCoder ships an update every 5 months, E/M Coder every 2 weeks. The most recent releases landed on June 9, 2026 and September 9, 2026 respectively.
