# DataMan vs Koyfin

The clearest difference is price: Koyfin at Free against DataMan's $0.99. Koyfin also leads on rating (4.9 vs 4.4) and update cadence (every 3 weeks vs every 3 months). DataMan's advantage is chart position (#15 vs unranked). On review sentiment, ratings volume, ads and in-app purchases there is nothing between them.

Koyfin is free to download; DataMan costs $0.99 up front. DataMan sells 2 in-app purchases, starting at $0.99 per month and Koyfin sells 4 in-app purchases, starting at $30.00 per month. Whichever you choose, the download price is not the number that matters.

Koyfin holds the better App Store score, 4.9 against 4.4. Both are backed by a comparable volume of ratings — 682 and 1.4K respectively. Written reviews complicate that: 81% of DataMan's written reviews are positive against 78% of Koyfin's, so the app with the better star average is not the one people write more warmly about.

DataMan ships an update every 3 months, Koyfin every 3 weeks. The most recent releases landed on September 30, 2026 and September 28, 2026 respectively.
