Verdict
The clearest difference is review sentiment: DO OR NOT at 100% against A WARMER's 7%. DO OR NOT also leads on update cadence (fortnightly vs every 2 months). A WARMER'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.
