PolyCounter is an amazing free software to count microfossils (or anything else) by Takeshi Nakagawa. It comes with a clean and intuitive user interface. You just need few minutes to get used to it and know how to set it. It provides counting alarms, real-time accumulation curve, and instant diagrams. Data are directly available in your directory as a csv file.
I strongly recommend it to whoever needs to analyze pollen samples!
