What it does
Klima is a mobile app designed to help individuals understand and neutralize their impact on the climate. It first guides users through a detailed questionnaire to calculate their personal carbon footprint. Based on this result, the app offers a monthly subscription service that funds a portfolio of certified climate projects, such as reforestation and solar power, effectively offsetting the user's emissions.
Where it shines
Klima excels in making the abstract concept of climate impact feel personal and actionable. The standout moment is the onboarding quiz itself, where a live counter at the top of the screen (visible from 00:27) dynamically adjusts the user's carbon footprint with every answer. This transforms a simple form into an interactive discovery tool. The app then powerfully contextualizes this result by comparing it to national and global averages (01:33), creating a strong emotional anchor before presenting a solution.
UX highlights
- Live Feedback: The constantly updating footprint number during the quiz provides immediate feedback, making the experience engaging rather than static.
- Value-First Approach: The app delivers a highly personalized and valuable piece of information, your exact carbon footprint, before asking for a sign-up or payment.
- Clear Visual Language: The use of clean layouts, simple icons, and a focused color palette makes complex information easy to digest.
- Contextual Actions: The final call to action on the paywall (03:38) is directly tied to the user's calculated footprint, framing the subscription as a solution to a personal problem.
- Organized Information: The project detail screens (e.g., at 04:23) are well-structured, providing a summary, impact details, photos, and a fact sheet to build trust and transparency.
Monetization & growth
Monetization is central to the app's purpose. After a mandatory sign-up, Klima presents a subscription paywall at 03:38. There is no free trial. Instead, the plans are framed around the user's calculated footprint, offering to offset 100%, 120%, or 200% of their impact. This directly connects the cost to the value proposition. The app also uses a soft-permission prompt for notifications at 04:05, offering to send a reminder later, which is a gentle way to re-engage users who aren't ready to commit.
Who it’s for
Klima is for environmentally-conscious individuals who feel overwhelmed by the scale of climate change and are looking for a simple, tangible way to take personal responsibility. It appeals to users who are motivated by data, appreciate transparency, and want to contribute to a solution but may not know where to start. The app effectively serves as a guided entry point into personal climate action.
Notes & opportunities
The onboarding is highly effective, but the mandatory sign-up at 02:18 could be a point of drop-off. Offering a guest mode to explore projects before committing to an account might retain more users. Additionally, while the footprint comparison is powerful, adding more interactive visualizations could further enhance the user's understanding of their impact breakdown.
