Changers Fit App: Playful team challenges for companies The Changers Fit App enables companies to strengthen health promotion and team building through exciting team challenges. Whether counting steps, running, cycling, or reducing CO₂ – the app motivates employees to get active together and achieve their goals. Main features: Versatile team challenges: Individually customizable competitions in the areas of steps, running, cycling, and CO₂ reduction promote team spirit and raise awareness for health and climate protection. Flexible tracking: Participants can manually record their activities via GPS, connect with Apple Health or Google Fit, or use automatic tracking with MotionTag AI. Additionally, integration with apps like Strava and wearables like Fitbit or Garmin is possible. Gamification elements: Leaderboards, collecting coins, awards, and nudging mechanisms increase employee motivation. Daily goals, such as 10,000 steps, encourage a healthy lifestyle. Reward system: Collected coins can be exchanged for rewards. Companies have the option to provide their own offers, such as vouchers or material prizes, in the integrated marketplace. Integration of CSR projects: Companies can present social projects and support them through employee achievements. Automatic tree planting makes successes visible and fosters a sense of community. Adaptability: The Changers Fit App is flexible and can be adapted to the needs of any company without additional software development. Content and functions can be easily managed via the SaaS administration platform. Battery performance: The Changers App is particularly energy-efficient. However, power consumption is higher when the GPS function is enabled compared to normal smartphone usage. Data protection and security: The software is, of course, GDPR-compliant. Data is hosted in Germany. Additionally, Changers has incorporated the requirements of works councils and employee representatives from previous contracts with German corporations into software development. This includes anonymous participation without real names and company email addresses, as well as the ability for users to delete their accounts directly within the app.

Summitree – Your Challenge App for More Activity and Sustainable Impact Move. Get active. Protect the climate – together as a team. With Summitree, every step and every sporting activity becomes a contribution to the environment. Take part in exciting, community-driven challenges, collect kilometers by running, hiking, or cycling, and turn your movement into real trees or other sustainable projects. How it works: • GPS tracking for outdoor activities: When you start running, hiking, or cycling, you can record your route directly via GPS. The app uses a foreground service while you are on the move – always visible and fully under your control. • Step counting via motion sensors: In our step challenges, your smartphone’s motion sensors automatically count your steps – no location data required. You can even keep the app closed, as long as you’ve granted permission for “physical activity.” • Be active together: Compete as a team, motivate each other, and reach your goals. • Create real impact: Transform your activities into trees or other sustainable projects. • Flexible and easy: Use the app anywhere – with automatic GPS tracking, step counting, or synchronization with your fitness tracker. Note: • As soon as an activity recording is started by a user – and only until the user stops the recording – the app may also capture location data in the background or when the phone is locked. For this, the permission for the foreground service is required. Features at a glance: • Join public or company challenges • GPS tracking for running, cycling, and hiking • Step counting via motion sensor (no location usage) • Manual activity entry and integration with supported fitness trackers • Team challenges for more motivation and team spirit • Personal statistics and leaderboards • Overview of your achieved climate impact Permissions notice: Summitree uses: • Location permission & foreground service when you actively start GPS tracking (e.g., for cycling). • Physical activity permission to count steps via your motion sensor – without using location data.
