Verdict
The clearest difference is review sentiment: Proesis Bio Donor at 100% against CSL Plasma's 19%. Proesis Bio Donor also leads on rating (4.4 vs 3.5) and monetization model (ad-supported vs free with in-app purchases). CSL Plasma's advantage is ratings volume (2K vs 16) and chart position (#56 vs unranked). On price, update cadence, 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.
Proesis Bio Donor holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: CSL Plasma has 2K ratings behind it against 16, so its average is the more settled of the two. Written reviews point the same way: 19% of CSL Plasma's written reviews are positive against 100% of Proesis Bio Donor's.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on November 3, 2026 and October 27, 2026 respectively.
