# SynScan Pro vs AstroVitals

The clearest difference is rating: AstroVitals at 3.7 against SynScan Pro's 2.7. AstroVitals also leads on monetization model (free vs paid) and review sentiment (50% vs 22%). SynScan Pro's advantage is ratings volume (56 vs 3) and iOS requirement (14.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

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

AstroVitals holds the better App Store score, 3.7 against 2.7. That said, the two scores are not equally well evidenced: SynScan Pro has 56 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 22% of SynScan Pro's written reviews are positive against 50% of AstroVitals's.

SynScan Pro ships an update every 2 months, AstroVitals every 3 weeks. Both last shipped on October 24, 2026.
