Klima - Fight climate change

What it does

Klima is an app designed to make climate action personal and accessible. Its core function is to help users understand their individual environmental impact by calculating their annual carbon footprint. Once calculated, the app offers a monthly subscription service that funds various certified climate projects—like reforestation, solar power, and clean cookstoves—to offset that footprint and help the user become carbon neutral.

Where it shines

Klima excels in making the abstract concept of a carbon footprint tangible and engaging. The onboarding quiz is a highlight; instead of being a static form, it features a live counter at the top of the screen that updates your footprint with every answer (00:38). This immediate feedback transforms data entry into a process of discovery. The app also smartly builds user investment before asking for money. By letting you vote on which project types matter most to you (03:11), it frames the subsequent subscription not as a purchase, but as a way to support a cause you've personally endorsed.

UX highlights

Dynamic Feedback: The live-updating carbon counter during the onboarding quiz provides constant, engaging feedback.
Contextual Benchmarking: At 01:32, the app doesn't just give you a number; it shows how your footprint compares to your country's and the world's average, making the data instantly meaningful.
Transparent Project Details: Users can explore detailed information about each climate project, including its location, methodology, and verification standard, fostering trust (04:23).
Clean Visuals: The interface is minimal and clean, with a consistent green and white color palette that reinforces the app's environmental mission.
Clear Calls to Action: Buttons are large, brightly colored, and use straightforward language like "Start offsetting" (03:04), guiding the user clearly through the flow.
Polished Micro-Interactions: Small animations, like the loading icon (02:38), are on-brand and add a layer of polish to the experience.

Monetization & growth

Monetization is central to the app's purpose. After the footprint calculation and account creation, the user is presented with a clear paywall at 03:38. There is no free trial offered. Instead, the user chooses how much of their footprint they want to offset (e.g., 100%, 120%, 200%), with corresponding monthly prices. This model positions the payment as a direct contribution to climate action. The app also uses a notification warm-up screen (04:05) to ask for permission to send reminders and updates, a common growth tactic to maintain engagement.

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, actionable way to make a positive impact. It appeals to users who are motivated by data, transparency, and the ability to see a direct link between their financial contribution and real-world projects. The app is likely most effective for people in developed countries, where carbon footprints are typically higher and disposable income for subscriptions is more common.

Notes & opportunities

The onboarding is long, requiring about three minutes to get to the main dashboard. While engaging, this could be a point of drop-off for less patient users. The app could potentially test showing a preview of the main app or the projects earlier to increase motivation. Additionally, the lack of a free trial might deter users who want to explore the app's features and project tracking before committing to a monthly payment. Offering a limited-time trial or a smaller, one-time contribution option could be an interesting experiment.
