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

Leading Recommendation from the comments
The leading recommendation seems to be Drip (bloodyhealth.gitlab.io)
Summarizing what people shared:
- accessible: it is on F-droid, Google Play, & iOS App Store
- 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."

Most data already provided won't be useful if they stop providing the data. Generally the concern is for miscarriages/abortions, so just change the data to indicate you were having a regular period and then request a data deletion/account close/stop using the app is actually pretty much as good as it's gonna get.
