Verdict

The call

The clearest difference is in-app purchases: Dekala at none against Thermometer's 1. Dekala also leads on ads (none vs shown). Thermometer's advantage is update cadence (every 2 months vs every 9 months) and ratings volume (4.2K vs 400). On price, rating, review sentiment and device support there is nothing between them.
