# Cellcard vs UMA Tune

The clearest difference is rating: Cellcard at 4.6 against UMA Tune's 3.6. Cellcard also leads on in-app purchases (none vs 2) and ratings volume (3.3K vs 5). UMA Tune's advantage is ads (none vs shown) and iOS requirement (10.0 vs 15.5.0). On price, review sentiment, update cadence and monetization model there is nothing between them.

Both are free to download. UMA Tune sells 2 one-off in-app purchases. Cellcard asks for nothing beyond the download.

Cellcard holds the better App Store score, 4.6 against 3.6. That said, the two scores are not equally well evidenced: Cellcard has 3.3K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 19% of Cellcard's written reviews are positive against 26% of UMA Tune's, so the app with the better star average is not the one people write more warmly about.

Cellcard ships an update weekly, UMA Tune every 2 weeks. The most recent releases landed on October 26, 2026 and October 20, 2026 respectively.
