Measure RPM
with your camera

TachoCamera turns your iPhone into a precision tachometer. No contact, no extra equipment — point, tune, read.

What it is

TachoCamera is the perfect tool for the visual inspection of high-speed moving objects — it lets you see, in real time, what stays blurred and invisible to the naked eye. It turns your iPhone into a professional stroboscope and a contactless speed meter. Measure the speed of a rotating machine and "freeze in place" a fast-moving product on any production line — without touching it, without sensors, and without stopping the machine.

🔄

Rotational motion

Motors, fans, shafts, pulleys, spindles, pumps. Measure their RPM while running and inspect the part as if it were standing still.

➡️

Linear & repetitive motion

Anywhere something is produced or moved at a set speed: production, conveyor, filling, packaging, labeling, textile, food, pharma and printing lines. The stroboscope freezes the moving product so you can see details impossible to catch at full speed.

What you can do

A classic LED stroboscope costs from a few hundred to several thousand dollars. TachoCamera does the same — and often lets you see more than a hardware stroboscope, especially on fast lines (hundreds of items per minute).

How it works

  1. Point your phone at the rotating or moving part.
  2. Tune the frequency (Hz or RPM) — the image freezes when the camera frequency synchronizes with the motion.
  3. Read the result — or use automatic detection: with good markers and lighting the app finds the speed by itself.

Who it's for

Any manufacturing company where something rotates or moves at a set speed — maintenance, service, process engineers, quality control, line and machine operators, mechanics and electricians. If you produce anything at a given speed, this tool is for you. And also enthusiasts and DIYers who want to measure RPM without expensive equipment.
