This should be a free app and people shouldn't pay for it. ### 1/5 — Carolina Biological Supply should be embarrashed! *2012-05-20* No thought was put into this app and it shows! I would never consider getting their pay for app (with only 20 pics!!! Hardly a guide to protozoa!) The main app is only one portrait mode and no landscape mode at all. Pictures and videos are only one landscape mode so you are constantly rotating the device. I got tired of messing with the app and just deleted it. Carolina Biological Supply should be embarrashed! ## Frequently asked questions about Protozoan Identification Free ### What is Protozoan Identification Free?
