Hi Product Hunt, I'm Theodor, one of the people behind CellCount. Cell culture labs still count cells by hand: a hemocytometer, a tally counter, and two people who never get the same number. Benchtop counters fix that, but they cost money and need their own slides. CellCount works from a photo of the chamber you already have. It finds the grid in the image by itself (or lets you place the crossings by hand when it cannot), counts the clear and blue cells, and does the cells per mL and viability math with your dilution. Every cell is marked on your image so you can check it, and nothing counts until you accept it. There is a Free plan, no card needed, and a free hemocytometer calculator if you count by hand: cellcount.ai/hemocytometer-calculator I'd love to hear what you count and what breaks.
