# Aligner vs Smilo

The clearest difference is review sentiment: Aligner at 100% against Smilo's 38%. Aligner also leads on iOS requirement (15.1 vs 17.0). Smilo's advantage is rating (4.5 vs 4.1). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Aligner sells 7 in-app purchases, starting at $2.99 per month and Smilo sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Smilo holds the better App Store score, 4.5 against 4.1. Both are backed by a comparable volume of ratings — 16 and 46 respectively. Written reviews complicate that: 100% of Aligner's written reviews are positive against 38% of Smilo's, so the app with the better star average is not the one people write more warmly about.

Aligner ships an update fortnightly, Smilo every 3 weeks. The most recent releases landed on October 15, 2026 and October 22, 2026 respectively.
