# Ruffio vs Stem Split

The clearest difference is rating: Ruffio at 4.4 against Stem Split's 2.3. Ruffio also leads on in-app purchases (none vs 1) and update cadence (every 10 days vs every 17 months). Stem Split's advantage is review sentiment (100% vs 66%). On price and ads there is nothing between them.

Both are free to download. Stem Split sells 1 one-off in-app purchase. Ruffio asks for nothing beyond the download.

Ruffio holds the better App Store score, 4.4 against 2.3. That said, the two scores are not equally well evidenced: Ruffio has 434 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 100% of Stem Split'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, Stem Split every 17 months. The most recent releases landed on September 13, 2026 and September 15, 2026 respectively.
