Verdict
The clearest difference is monetization model: Seek Thermal at free against Thermal P2's paid. Seek Thermal also leads on rating (2.5 vs 2.1) and ratings volume (321 vs 27). Thermal P2's advantage is update cadence (fortnightly vs every 3 months). On price, ads, in-app purchases and device support there is nothing between them.
