# M2DX vs S

The clearest difference is rating: S at 4.5 against M2DX's 3.7. S also leads on in-app purchases (none vs 1) and iOS requirement (16.0 vs 18.0). M2DX's advantage is update cadence (every 2 days vs every 6 weeks) and review sentiment (25% vs 0%). On price, ratings volume, ads and monetization model there is nothing between them.

Both are free to download. M2DX sells 1 one-off in-app purchase. S asks for nothing beyond the download.

S holds the better App Store score, 4.5 against 3.7. Both are backed by a comparable volume of ratings — 3 and 4 respectively. Written reviews complicate that: 25% of M2DX's written reviews are positive against 0% of S's, so the app with the better star average is not the one people write more warmly about.

M2DX ships an update every 2 days, S every 6 weeks. The most recent releases landed on October 8, 2026 and October 12, 2026 respectively.
