About this app

The Zooniverse is the world’s largest and most popular platform for people-powered research. This research is made possible by volunteers—hundreds of thousands of people around the world who come together to assist professional researchers. Our goal is to enable research that would not be possible, or practical, otherwise. Zooniverse research results in new discoveries, datasets useful to the wider research community, and many publications.

The Zooniverse Mobile App provides push notification updates about our projects, as well as access to our most mobile-friendly projects and publications.

This app is brilliant. Being a citizen scientist is even better! I've been using Zooniverse for years. It brings many projects into one app. The website is really good but the additional of this clean, easy to use and navigate app just makes data recording more accessible to people. I had an issue with one project page, I reported it and the CEO of Zooniverse contacted me directly to thank me and let me know it was fixed. Absolutely fantastic customer service.

Some of the studies are very technical I suppose you could say. They are always accompanied by a very clear demonstration and you can refer back to the material at any time you aren't sure. It's a brilliant way to participate in science while stuck on the bus in traffic or while you are waiting for your other half to finish getting ready to go out. Anything that would normally feel like wasted time you can quickly, pick up this app and Boom

I have been looking for an app like this for years! It is still a very small app with a small database, but I am hopeful that it will increase soon! To be able to help in research, especially wildlife research, is very important to me!
