Needs to filter based on criteria

All in all, I’m very happy to participate in these studies. For all the people complaining about “lack of compensation” I would say that sometime we should just do things because they help others, not because we personally get compensation for it.

Knocking off one star because it needs to filter the studies based on eligibility criteria. As a guy, I cannot possible participate in a cycle tracking studies, so it should either not be show at all or have an option to dismiss from your available studies due to ineligibility.

Power beats pro don’t count for some reason

I’ve been trying to work and help with a couple studies. And for some reason the Powerbeats pro earbuds don’t count as compatible your buds for the audio test. I don’t know why but they do work with Apple play and have in your volume adjustment and loudness detection like AirPods do and I know it works with Apple but for some reason it’s not working with this app.

Biased, Marketing strategy for Apple Watch

I’m an ultra runner and want to contribute to the heart and fitness studies. It says you need to record your workouts with an Apple Watch for the studies. Apple watches are activity trackers, not true fitness watches. My Garmin fitness watch is designed for athletes and adventurist (and other brands like Suunto) provide much better data than Apple watches, yet the wording sounds like I cannot contribute my data to the study. Why not let let us sync Strava, Garmin Connect, or another app’s heart data?

Minus 1 star for marketing bias.
Minus another star for not allowing non-Apple fitness watches to contribute data. Minus another star for no heart rate monitor strap support.
