Verdict

The call

The clearest difference is rating: Three at 4.4 against Klevio's 1.9. Three also leads on ratings volume (1.2K vs 13) and update cadence (every 2 weeks vs every 2 months). Klevio's advantage is ads (none vs shown) and review sentiment (40% vs 18%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Three holds the better App Store score, 4.4 against 1.9. That said, the two scores are not equally well evidenced: Three has 1.2K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 18% of Three's written reviews are positive against 40% of Klevio's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Three ships an update every 2 weeks, Klevio every 2 months. The most recent releases landed on October 9, 2026 and October 7, 2026 respectively.
