Online lab counter
Use the website when you need to count something now — cells on a slide, colonies on a plate, samples through a queue — without installing an app or creating an account. Count with the mouse or the number keys, set a limit so you hear it when you hit your target, and switch to focus mode when the count is all that matters.

About this counter
A normal counter is one large tap area with a single number. A multi counter puts two to six named, color-coded counters in a grid with a running total — enough for a 100-cell differential or a four-way sort. Every counter can carry its own limit, and the multi counter can also cap the total.
How it works
- 1Start a normal counter, or create a multi counter with 2–6 named counters.
- 2Click a counter (or press its number key) to count up; Shift or the minus button counts down.
- 3Set a limit with the bell button and hear an alarm when the count reaches it.
Who is this for?
Researchers, students, and technicians who count by hand — differentials down the microscope, colonies on a plate, passages, samples, or anything else where losing your place means starting over.
