quickstart

You don't need to read this page to use temmet, but if you'd like a guided thirty seconds, here it is.

1. open the app

Go to temmet.app. You'll land on the setup screen with a mode toggle near the top.

2. pick a mode

  • Simple mode — one slider for people, one for the average hourly rate. Best when everyone in the session costs roughly the same. Try this first.
  • Advanced mode — add named participants, each with their own role and hourly rate. Use this when you want a per-person breakdown afterwards, or when rates differ a lot.

You can save an Advanced setup as a template to reuse later in one click.

3. press TIME = MONEY

That big button at the top starts the meter. The cost begins climbing immediately. The page-title even reads the running total, so you can see it from a peek at the tab strip.

While the session is running, participant names and roles are hidden — the screen shows "Participant 1", "Participant 2", and so on. The rates remain visible; the identities do not. This means you can share your screen or place your phone on the table without exposing what anyone earns.

4. pause or end

  • space pauses and resumes. Useful if someone steps out for a few minutes.
  • esc ends the session. The summary screen opens, and the session is automatically saved to your history — no confirm, no save button.

You can rename the session on the summary screen by clicking the label field. The new name is committed when you tab away.

what next

  • Look at history to see past sessions, search across them, sort, and export.
  • Add a custom role with its own rate so future sessions are one tap.
  • Read the recipes for use cases beyond meetings.
