# Ruff vs Roo AI

The clearest difference is ads: Ruff at none against Roo AI's shown. Roo AI's advantage is update cadence (every 3 days vs every 3 weeks) and monetization model (ad-supported vs free with in-app purchases). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Ruff sells 5 in-app purchases, starting at $5.00 per 7 days and Roo AI sells 1 in-app purchase, starting at $0.99 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 Ruff against 5.0 for Roo AI. Both are backed by a comparable volume of ratings — 1 and 3 respectively.

Ruff ships an update every 3 weeks, Roo AI every 3 days. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
