# Opal vs Grit

The clearest difference is update cadence: Opal at every 6 days against Grit's fortnightly. Opal also leads on chart position (#42 vs unranked) and ratings volume (91K vs 16K). Grit's advantage is review sentiment (72% vs 61%) and device support (5 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Opal sells 8 in-app purchases, starting at $4.99 per 7 days and Grit sells 9 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Opal against 4.8 for Grit. That said, the two scores are not equally well evidenced: Opal has 91K ratings behind it against 16K, so its average is the more settled of the two. Written reviews are what separate them: 61% of Opal's written reviews are positive against 72% of Grit's.

Opal ships an update every 6 days, Grit fortnightly. Both last shipped on November 4, 2026.
