Verdict

The call

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.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
