# Superfluent vs Mio

The clearest difference is rating: Superfluent at 4.9 against Mio's 4.5. Superfluent also leads on ratings volume (4.1K vs 2). Mio's advantage is update cadence (every 2 days vs every 6 days). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Superfluent sells 10 in-app purchases, starting at $10.99 per month and Mio sells 6 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Superfluent holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Superfluent has 4.1K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 93% of Superfluent's written reviews are positive against 100% of Mio's, so the app with the better star average is not the one people write more warmly about.

Superfluent ships an update every 6 days, Mio every 2 days. The most recent releases landed on November 14, 2026 and November 15, 2026 respectively.
