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.

Your Fellow Human Being


[Soap box ON]

Always expecting to be paid for SIMPLY HELPING your fellow human being is an example of the WORST of human behavior: greed!

Helping, TRULY, has its own rewards, and ANYONE could find themselves in a similar situation in the future.

In order to deal with modern society’s problems, which are NOT, IN ANYWAY WHATSOEVER, contained within ANY country’s borders (“wall” or not), we MUST WORK TOGETHER! We have ONE PLANET, with a rapidly, ever-increasing population. We no longer have the “luxury” of simply moving to another part of the world!

Think of what could be done if all the “defense” budgets were used to feed people and cure diseases???! All those who say “that’s not realistic” are outnumbered by hundreds to one (especially if their jobs depend on CONSTANT CONFLICT)!

Babies are NOT, are NOT, are NOT, NOT, NOT born with ANY ENEMIES!!!

Why are these SIMPLE facts not recognized by EVERYONE?!

Paving the way to a better future

I just like to think that if I could help and contribute to medical science, it’s the least I could do in this thoroughly thought out way by using our devices. With that note though, I like to say that since I’ve been in this research app, my Apple Watch battery level has been draining significantly.
