# Quinterval vs Chords

The clearest difference is in-app purchases: Chords at none against Quinterval's 1. Chords also leads on update cadence (every 9 days vs every 8 months) and rating (4.6 vs 4.4). Quinterval's advantage is ads (none vs shown) and review sentiment (78% vs 68%). On price, ratings volume and device support there is nothing between them.

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

Chords holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 21 and 58 respectively. Written reviews complicate that: 78% of Quinterval's written reviews are positive against 68% of Chords's, so the app with the better star average is not the one people write more warmly about.

Quinterval ships an update every 8 months, Chords every 9 days. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
