What is ClickDose?
ClickDose is a free tool that counts the clicks on a GLP-1 injection pen — Wegovy, Ozempic or Mounjaro — and turns them into a precise dose. On these pens, each click you hear while dialling corresponds to a fixed, known increment of medicine, so counting clicks lets you dial a smaller "split" dose. That helps when you titrate slowly to ease side effects, or stretch an expensive pen further.
The click detection runs entirely in your browser using your device's microphone — your audio and dose calculations are never uploaded or stored. ClickDose also works offline once installed as an app.
Important — not a medical device
ClickDose is an assistive tool only, and is not affiliated with, endorsed by, or funded by Novo Nordisk or Eli Lilly. Click counting can be inaccurate due to background noise or microphone differences — always verify your dose visually on the pen and follow your doctor's instructions. It is built by Tue Topholm, a software engineer and patient/family member (not a clinician).
