Well designed and very helpful!

This is a great app; really helpful, and well designed. I love the flash card options and the guide progression starting with general body shape and working into more detail!

It would be really helpful to see what magnification is used for photos, and of course to see more species added to this app overall.

However, overall this is a great app and very appreciated!!!

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

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.
