Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. iO sells 1 one-off in-app purchase and Spinner.io sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
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.
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.
