Come get moving, have fun, and collect valuable Klima-Taler. The app tracks your journeys on foot, by bike, and on public transport. It calculates the CO₂ savings and generates one Klima-Taler for every 5 kilograms saved. You can redeem your Klima-Taler for free entry and discounts at sports and cultural events, swimming pools, museums, and of course with over 500 local partners. What else you can explore in the app: • Practical tips to reduce your footprint • Energy-saving ideas for everyday life • City challenges and competitions • A map of sustainable places near you • Local news and updates from your municipality • 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 rating: Klima at 5.0 against TK's 1.4. Klima also leads on review sentiment (74% vs 64%) and iOS requirement (13.0 vs 18.0). TK's advantage is ratings volume (15 vs 1) and monetization model (free vs ad-supported). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Klima holds the better App Store score, 5.0 against 1.4. That said, the two scores are not equally well evidenced: TK has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 74% of Klima's written reviews are positive against 64% of TK's.
Klima ships an update every 4 weeks, TK every 5 weeks. Both last shipped on October 25, 2026.
