About 9Darts

What 9Darts is, why it works offline, why it is free, who makes it, and how to get in touch about a bug or a rule your league plays.

Last updated: 22 October 2026

9Darts is a dart counter for your phone. It scores 301, 501 and Around the World, either from a number grid or by tapping the board itself, shows you the ways out once you are in finishing range, and keeps per-player statistics that a built-in coach turns into the next drill worth throwing.

It is a web app, so there is nothing to install from a store — open it once and add it to your home screen. There is no sign-up: no email address, no password, nothing to be logged in as. Your games are saved on your phone, not on a server.

Offline first, and that is not a slogan

Dartboards live in basements, garages and pubs with one bar of signal. Every solo game and every drill works with the radio off, because after the first visit the app is served entirely from your own phone. The one thing that needs a connection is playing a mate on another phone, which is optional.

What it costs

Everything is free, and there is nothing to buy: no trial, no time limit and no locked half. Every game and every mode — 301, 501, Around the World, the bot at all five levels, a mate scoring on another phone — and the training half with it: the full statistics screen, with your trend over time, scoring bands, treble rate, the doubles ladder, the heat map and your record against each bot; every stored game, turn by turn; and all five drills.

What pays for it is a small ad on the screens between games — never on the game screen itself while you are throwing. And what is never held back is your own data: the app saves every game, and the export in Settings hands you all of them, to keep or to move to another phone.

Who makes it

Made in Slovakia by Richard Kollar. It started as a counter for playing at home and grew because a spreadsheet of averages is not a training partner.

The typeface

The Classic typeface in Settings is Libre Baskerville, by Impallari Type, under the SIL Open Font License; the standard face is whatever your phone uses for everything else.
