Verdict
The clearest difference is rating: Kadmos at 5.0 against MarTrust's 4.6. MarTrust's advantage is review sentiment (75% vs 55%) and monetization model (free vs ad-supported). On price, update cadence, ads and in-app purchases 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.
Kadmos holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: MarTrust has 25 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 55% of Kadmos's written reviews are positive against 75% of MarTrust's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 8, 2026 and September 9, 2026 respectively.
