# AlignerTime vs TrayZen

The clearest difference is rating: AlignerTime at 4.4 against TrayZen's 3.0. TrayZen's advantage is in-app purchases (none vs 4) and update cadence (weekly vs every 3 weeks). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. AlignerTime sells 4 in-app purchases, starting at $3.99 per month. TrayZen asks for nothing beyond the download.

AlignerTime holds the better App Store score, 4.4 against 3.0. Both are backed by a comparable volume of ratings — 8 and 3 respectively. Written reviews complicate that: 89% of AlignerTime's written reviews are positive against 100% of TrayZen's, so the app with the better star average is not the one people write more warmly about.

AlignerTime ships an update every 3 weeks, TrayZen weekly. Both last shipped on October 31, 2026.
