# TTLock vs SeTracker2

The clearest difference is in-app purchases: TTLock at none against SeTracker2's 22. TTLock also leads on device support (4 vs 2) and iOS requirement (13.0 vs 15.0). SeTracker2's advantage is rating (3.2 vs 2.8) and ratings volume (2.6K vs 523). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. SeTracker2 sells 14 in-app purchases, starting at $0.49 per month. TTLock asks for nothing beyond the download.

SeTracker2 holds the better App Store score, 3.2 against 2.8. Both are backed by a comparable volume of ratings — 523 and 2.6K respectively. Written reviews complicate that: 25% of TTLock's written reviews are positive against 20% of SeTracker2's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on September 23, 2026.
