How many people used the tracking app for how long? How were they chosen?
The study would be flawed if the group is not chosen to represent correctly the entire population. E.g., if they called for volunteers using the app, mostly people will apply that are engaged in climate change mitigation anyway and / or are in the target market for the 49 Euro ticket.
