# Dyno vs Arc 9

The clearest difference is ads: Dyno at none against Arc 9's shown. Dyno also leads on ratings volume (1K vs 1) and update cadence (every 3 days vs weekly). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Dyno sells 10 one-off in-app purchases and Arc 9 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Dyno against 5.0 for Arc 9. That said, the two scores are not equally well evidenced: Dyno has 1K ratings behind it against 1, so its average is the more settled of the two.

Dyno ships an update every 3 days, Arc 9 weekly. The most recent releases landed on November 7, 2026 and October 31, 2026 respectively.
