# Opal vs Flicker

The clearest difference is update cadence: Flicker at daily against Opal's every 8 days. Flicker also leads on iOS requirement (15.1 vs 18.1). Opal's advantage is ratings volume (37 vs 2). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Opal sells 1 in-app purchase, starting at $7.99 per month and Flicker sells 2 in-app purchases, starting at $3.99 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 — 5.0 for Opal against 5.0 for Flicker. That said, the two scores are not equally well evidenced: Opal has 37 ratings behind it against 2, so its average is the more settled of the two.

Opal ships an update every 8 days, Flicker daily. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
