# OSAIO vs ViewLink

OSAIO and ViewLink both sit at 4.6 stars, but that hides the real split: 64% of OSAIO's written reviews are positive against 0% of ViewLink's. OSAIO also leads on update cadence (weekly vs every 6 months) and ratings volume (2.6K vs 20). On price, rating, ads and in-app purchases there is nothing between them.

ViewLink holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: OSAIO has 2.6K ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 64% of OSAIO's written reviews are positive against 0% of ViewLink's, so the app with the better star average is not the one people write more warmly about.

OSAIO ships an update weekly, ViewLink every 6 months. The most recent releases landed on September 26, 2026 and September 15, 2026 respectively.
