Ratings and Reviews

Phyto introduces you to the tiny world of phytoplankton


Based on information from the Phytoplankton Monitoring Network developed by the National Oceanic and Atmospheric Administration (NOAA), this application does what it says it does: it is an identification guide for phytoplankton and includes spoken pronunciation of each type, and multiple photos taken with a light microscope. In flash card mode, you can use it to hone your skills at phytoplankton identification. A little app for little creatures.

Interesting app but would like more details

Tidepool tunicate

This app has nice pictures and the pronunciation is an interesting addition but it would be so much more valuable if it also had some natural history info about the plankton and where it is found, etc.

Useful and fun


This is a great tool if you are in the field and don't have access to an ID guide. Flash card game is fun if you are waiting your turn at the dentist or DMV!
Distribution range information would be a nice addition.
