As an undergrad majoring in biology, it’s a lot of fun to be able to help with real-world research! ### 2/5 — Cool. *2026-03-19, version 2.15.2* It’s cool, but also rather slow. 🫤 ### 4/5 — Cool! But! *2025-01-16, version 2.13.0* A filter to hide “out of data” projects would make finding a joinable project much easier. Also an All Projects list would be handy. ### 1/5 — Got my hopes up ): *2023-10-10, version 2.9.2* I know you guys have a small team and I really respect the work you’re doing. However, I cannot stress what a bummer it is to be disabled, stuck in bed some days, and log into the app only to be told none of the projects I’m working on are mobile friendly. None of them??? None of the tasks I’m doing involve more than looking at pictures and clicking a couple buttons. If that’s really the case, it seems like this app is still in alpha and doesn’t really have many features built out. Again, I want it to keep improving! It just feels not quite ready for primetime as-is. I also see the last update was about a year ago, so it feels like maybe this project is on hold, or presented too many challenges to adapt for mobile. ### 1/5 — Good website bad app *2022-08-27, version 2.8.2* On the app it is super hard to find projects. There is also no search box. The website is really good though. Check out the website. ### 4/5 — App Does Not Remember My Password *2022-06-30, version 2.8.2* I really like this app. It is incredibly interesting and fun. But I haven’t been able to sign in as it doesn’t seem to remember my password. I know I’m using the right password as I can log in to the website with it. Fix the security issue and this is a 5 star app. ### 4/5 — Yay mobile classifications *2021-09-30* Love it, that I can use Zooniverse on my phone. However, two wishes from my side: - opening images currently means I need to open them via a small icon and close them via the small cross. A double tap feature to open and then close would really help to access details quicker. Plus the cross to close the detail view doesn’t properly work when you are zoomed in on an image - space on a mobile screen is very limited, but currently ~20% is wasted on the left and right to an image. It would help to have a larger image to look at ### 4/5 — Good app, but ... *2021-01-18* ... is there real a white font color on white background in the registration/log process? ### 2/5 — Wish I could get past page 1 *2020-12-10, version 2.8.2* Every time I tried to get to the 2nd page of instructions, it crashes. I loved this on my desktop, but the phone version needs to be fixed! ### 4/5 — One of the best apps for citizen science, but it really needs a dark mode.. *2020-12-08, version 2.8.2* This is one of my favourite apps for citizen science projects. The only issue I have is that the interface design looks quite outdated and in dire need of dark mode. Would give 5 stars if that was fixed. ## Frequently asked questions about Zooniverse ### What is Zooniverse?
