Verdict
The clearest difference is rating: TTLock at 2.9 against Room Heat's 1.8. TTLock also leads on update cadence (every 3 weeks vs every 9 months) and ratings volume (547 vs 9). Room Heat's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, review sentiment and in-app purchases there is nothing between them.
