# Fixu vs Aligner Tracker

The clearest difference is review sentiment: Fixu at 100% against Aligner Tracker's 33%. Fixu also leads on in-app purchases (none vs 6) and iOS requirement (15.1 vs 17.0). Aligner Tracker's advantage is rating (4.2 vs 3.0) and ratings volume (30 vs 2). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Aligner Tracker sells 6 in-app purchases, starting at $4.99 per 7 days. Fixu asks for nothing beyond the download.

Aligner Tracker holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: Aligner Tracker has 30 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Fixu's written reviews are positive against 33% of Aligner Tracker's, so the app with the better star average is not the one people write more warmly about.

Fixu ships an update weekly, Aligner Tracker fortnightly. The most recent releases landed on September 30, 2026 and October 5, 2026 respectively.
