# Microsoft Azure vs BIO

Microsoft Azure and BIO both sit at 4.8 stars, but that hides the real split: 100% of BIO's written reviews are positive against 29% of Microsoft Azure's. BIO also leads on iOS requirement (13.2 vs 16.0). Microsoft Azure's advantage is ratings volume (2.8K vs 13) and update cadence (every 4 weeks vs every 3 months). On price, rating, 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.

On the App Store both sit at effectively the same score — 4.8 for Microsoft Azure against 4.7 for BIO. That said, the two scores are not equally well evidenced: Microsoft Azure has 2.8K ratings behind it against 13, so its average is the more settled of the two. Written reviews are what separate them: 29% of Microsoft Azure's written reviews are positive against 100% of BIO's.

Microsoft Azure ships an update every 4 weeks, BIO every 3 months. The most recent releases landed on September 21, 2026 and September 10, 2026 respectively.
