# Ruffio vs Gaudio Studio

The clearest difference is in-app purchases: Ruffio at none against Gaudio Studio's 5. Ruffio also leads on rating (4.5 vs 4.0) and ratings volume (442 vs 4). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Gaudio Studio sells 4 one-off in-app purchases. Ruffio asks for nothing beyond the download.

Ruffio holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Ruffio has 442 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 66% of Ruffio's written reviews are positive against 68% of Gaudio Studio's, so the app with the better star average is not the one people write more warmly about.

Ruffio ships an update every 10 days, Gaudio Studio fortnightly. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
