# Play vs Ultramarine

The clearest difference is rating: Play at 4.5 against Ultramarine's 1.6. Play also leads on update cadence (every 2 months vs every 17 months) and ratings volume (3.5K vs 40). Ultramarine's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Play holds the better App Store score, 4.5 against 1.6. That said, the two scores are not equally well evidenced: Play has 3.5K ratings behind it against 40, so its average is the more settled of the two. Written reviews point the same way: 25% of Play's written reviews are positive against 9% of Ultramarine's.

Play ships an update every 2 months, Ultramarine every 17 months. The most recent releases landed on November 6, 2026 and November 1, 2026 respectively.
