# OnPage vs ThreatLocker

The clearest difference is rating: ThreatLocker at 5.0 against OnPage's 4.2. ThreatLocker also leads on monetization model (free vs subscription). OnPage's advantage is ratings volume (1.4K vs 3) and iOS requirement (13.0 vs 15.1). 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.

ThreatLocker holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: OnPage has 1.4K ratings behind it against 3, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 28, 2026 and September 24, 2026 respectively.
