# Sonar vs think

The clearest difference is in-app purchases: Sonar at none against think's 1. Sonar also leads on ratings volume (30 vs 2) and iOS requirement (13.4 vs 16.0). think's advantage is ads (none vs shown) and update cadence (every 2 weeks vs monthly). On price, rating and device support there is nothing between them.

Both are free to download. think sells 1 one-off in-app purchase. Sonar asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Sonar against 5.0 for think. That said, the two scores are not equally well evidenced: Sonar has 30 ratings behind it against 2, so its average is the more settled of the two.

Sonar ships an update monthly, think every 2 weeks. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
