Useless. *2021-04-27, version 1.91* As of April 2021 the App is pretty much dead. Constantly gives error connecting and will not load pictures or data. ### 1/5 — Shuts off *2020-09-02, version 1.91* I try viewing from the list of over two thousand fish and after a few minutes every time the app just shuts down! And starts over at the top of the list!!!😡😡😡 ### 1/5 — The worst app ever *2020-07-09, version 1.91* You should never get this app ### 1/5 — Soooo slooooww *2019-08-10, version 1.91* And to you have to pay to fix it ### 1/5 — Terrible *2019-06-02, version 1.91* You have to pay EXTRA to use your own pictures ### 3/5 — Amazing but the loading is really long *2019-05-16, version 1.91* This a great app and the app I’d been looking for ever.But the only problem with this app is that the pictures take to long to load.And also the game crashes and I have to start over and load again. ### 1/5 — Crapapp app ap *2018-09-14, version 1.91* Stupidest app ever.

Not to mention it takes half an hour to load... ### 1/5 — Lame *2018-06-09, version 1.91* Takes forever to load, crashed once as well. And it doesn’t really help you identify the fish you have. ### 5/5 — Wonderful Guide *2018-01-23, version 1.9* This is a great catalog of fish species with photos. I would love to see it filled out even more in future updates. ## Frequently asked questions about WhatFish, Identification Guide ### What is WhatFish?
