Verdict

The call

The clearest difference is rating: Spinner.io at 4.7 against iO's 3.7. Spinner.io also leads on ratings volume (227K vs 19). iO's advantage is ads (none vs shown) and review sentiment (71% vs 49%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Spinner.io holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Spinner.io has 227K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 71% of iO's written reviews are positive against 49% of Spinner.io's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iO ships an update every 6 weeks, Spinner.io every 3 weeks. The most recent releases landed on November 1, 2026 and November 10, 2026 respectively.
