App Showcase: Klima

What it does

Klima is a mobile app designed to help individuals take direct action on climate change. It first guides users through a personalized quiz to calculate their annual carbon footprint. Based on the result, the app offers a monthly subscription service that funds certified, high-impact climate projects—such as reforestation and renewable energy—to offset the user's emissions and help them live a carbon-neutral life.

Where it shines

The app's strength lies in making the abstract concept of climate change personal and actionable. The onboarding quiz (00:32) is a standout moment, with a live counter that updates the user's footprint in real-time. This provides instant, tangible feedback that is both educational and engaging. Furthermore, the app builds trust through transparency, offering detailed pages for each climate project (04:17) with summaries, photos, and verification standards.

UX highlights

• Dynamic Feedback: The live-updating carbon footprint counter (00:37) during the quiz turns a simple form into an interactive discovery tool.
• Conversational Interface: Questions are presented in a chat-like format, which makes the onboarding process feel friendly and approachable.
• Clear Narrative Structure: The app first establishes the user's problem (their carbon footprint at 01:28) before presenting the solution (the app's features at 01:42), making the value proposition highly compelling.
• Progressive Disclosure: Information about complex climate projects is layered. Users get a high-level overview first (03:10), can tap for a quick summary, and then dive into a full detail page, preventing information overload.
• Visual Impact Breakdown: The results screen (01:33) uses a simple bar chart to show how different lifestyle categories contribute to the user's total footprint, offering clear insights at a glance.

Monetization & growth

Klima uses a soft paywall model. The core value—calculating one's footprint—is delivered for free. Monetization occurs when the user decides to take action. After signing up, the app presents a subscription screen (03:38) where users can choose to offset a percentage of their footprint (e.g., 100%, 120%, 200%). The pricing is presented clearly on a per-month basis. There is no free trial offered; the model is a direct subscription to fund climate projects. The app also includes a notification warm-up screen (04:04) to send reminders, a subtle retention mechanic.

Who it’s for

The app is for environmentally-conscious individuals who feel the urgency of climate change but are unsure how to make a meaningful impact. It appeals to users who value transparency and want a simple, automated way to contribute to verified climate solutions. It targets people who are motivated by data and want to understand their personal role in a global issue.

Notes & opportunities

While the onboarding is engaging, its length could be a point of friction for some users. A/B testing a shorter quiz might reveal opportunities to get users to the value proposition faster. On the main dashboard, the project cards are well-designed, but the app could further enhance engagement by adding more dynamic content, such as recent news or progress updates directly from the project sites, to make the user's ongoing contribution feel more alive.
