What else you can explore in the app: β’ Practical tips to reduce your footprint β’ Energy-saving ideas for everyday life β’ City challenges and competitions β’ A map of sustainable places near you β’ Local news and updates from your municipality β’ Community donation projects The Klima-Taler app is particularly battery-friendly. Nevertheless, the consumption is higher when the GPS function is switched on than when the smartphone is in normal operation. We need GPS in order to recognize the modes of transport and to be able to reward you with Klima-Taler. Data protection is our highest priority. We host the app in Germany in compliance with GDPR.

Verdict
The clearest difference is review sentiment: Klima at 74% against Summitree's 29%. Klima also leads on iOS requirement (13.0 vs 15.0). Summitree's advantage is update cadence (every 9 days vs every 4 weeks) and monetization model (free vs ad-supported). On price, ads, in-app purchases and device support there is nothing between them.
