# Sub vs InstaViewSafe

The clearest difference is rating: Sub at 4.4 against InstaViewSafe's 3.1. Sub also leads on in-app purchases (none vs 2) and ratings volume (778 vs 7). InstaViewSafe's advantage is review sentiment (33% vs 15%) and update cadence (every 2 weeks vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. InstaViewSafe sells 2 one-off in-app purchases. Sub asks for nothing beyond the download.

Sub holds the better App Store score, 4.4 against 3.1. That said, the two scores are not equally well evidenced: Sub has 778 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 15% of Sub's written reviews are positive against 33% of InstaViewSafe's, so the app with the better star average is not the one people write more warmly about.

Sub ships an update every 5 weeks, InstaViewSafe every 2 weeks. Both last shipped on October 17, 2026.
