There are downsides with downloading their app just to input bad data, but it's a fun thought.
edit: While we're at it we might as well offer an alternative app to people.
I posted in [email protected] to collect recommendations for better apps

- does not allow any third-party tracking
- the project got support from "PrototypeFund & Germany's Federal Ministry of Education and Research, the Superrr Lab and Mozilla"
- Listed features:
- "Your data, your choice: Everything you enter stays on your device"
- "Not another cute, pink app: drip is designed with gender inclusivity in mind."
- "Your body is not a black box: drip is transparent in its calculations and encourages you to think for yourself."
- "Track what you like: Just your period, or detect your fertility using the symptothermal method."

Would a bunch of users entering garbage data, with not all of them being totally obvious, make it harder to sell that data? Possibly.
It might take a while for thier customers to notice that the data is garbage, or they might develop a way to figure out what data is garbage and still sell other data gathered from the OS/sensors etc from users trying to poison the data.
