How much leaf for your pot? Choose a type, set the volume, and get grams, temperature and time — with the gong fu alternative underneath.

Times, temperatures and ratios come from Teafinity’s curated tea library.
Which tool do you need?
If you brew in a mug or a teapot, start with the tea timer: choose a type, press start, and stop steeping when it rings. If you brew in a gaiwan or a small clay pot, use the gong fu timer instead — it counts a whole series of short infusions rather than one long one, and it remembers where you are in the series.
The steeping calculator answers the question the other two do not: how much leaf. Tell it the size of your pot and how strong you like your tea, and it scales the ratio for you in grams, with the matching temperature and time. The caffeine calculator is for the other end of the day — it ranks teas by milligrams per cup and works out the hour to stop drinking.
All four read from the same curated data as the Teafinity app, so a sencha behaves the same way here as it does on your phone. Nothing you type is uploaded, nothing needs an account, and each page keeps the numbers as plain HTML tables so you can print them or paste them into a note.
Frequently asked questions
Are these tools really free?
Yes. There is no sign-up, no trial and no limit on how many times you can use them. The Teafinity app is the paid product; these pages are not gated.
Do they work offline?
Once a page has loaded, yes — the timer keeps counting with the connection off.
Where do the times come from?
From Teafinity’s tea library — the same curated data that powers the app.
Can I use these on my phone?
Yes, all four are built mobile-first. The timers keep the screen awake while they run, so the countdown stays visible.
The same timings, in your pocket
Teafinity rings while your phone is locked. The download is free on iPhone and Android and includes 30 teas; the rest of the library is Premium.
