# Chord Calculus vs Tihai Pro

The clearest difference is rating: Tihai Pro at 4.7 against Chord Calculus's 3.9. Tihai Pro also leads on price ($0.99 vs $2.99). Chord Calculus's advantage is in-app purchases (none vs 1) and review sentiment (80% vs 50%). On ratings volume, ads, monetization model and device support there is nothing between them.

Chord Calculus costs $2.99 and Tihai Pro $0.99 up front. Tihai Pro sells 1 one-off in-app purchase. Chord Calculus asks for nothing beyond the download.

Tihai Pro holds the better App Store score, 4.7 against 3.9. Both are backed by a comparable volume of ratings — 8 and 12 respectively. Written reviews complicate that: 80% of Chord Calculus's written reviews are positive against 50% of Tihai Pro's, so the app with the better star average is not the one people write more warmly about.

Chord Calculus ships an update fortnightly, Tihai Pro every 3 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
