Verdict
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.
