# Blutspende vs DocCheck Flexikon

The clearest difference is rating: Blutspende at 4.8 against DocCheck Flexikon's 4.3. Blutspende also leads on ratings volume (49 vs 9). DocCheck Flexikon's advantage is update cadence (every 6 weeks vs every 8 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Blutspende holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Blutspende has 49 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 91% of Blutspende's written reviews are positive against 95% of DocCheck Flexikon's, so the app with the better star average is not the one people write more warmly about.

Blutspende ships an update every 8 months, DocCheck Flexikon every 6 weeks. The most recent releases landed on October 15, 2026 and October 16, 2026 respectively.
