Flip a coin online for an instant heads or tails result. Free, private, fair, and no signup required.
Tap the coin for an instant heads or tails result.
Use it for quick decisions, games, or choosing who goes first.
Sometimes all you need is a clear result.
With CoinFlipTool, each flip is immediate and unbiased, giving you a consistent coin toss experience every time — without worrying about physical imperfections, inconsistent throws, or not having a coin nearby.
Whether you're choosing who goes first, settling a small disagreement, or making a quick call, the process stays fast, simple, and dependable.
The interface is designed to get out of your way.
The core experience stays familiar across phones, tablets, and computers, with small device-specific optimizations where they make the app faster or easier to use. On mobile, a dedicated Flip a Coin Mode removes everything except the coin — making it even faster when you need a quick virtual coin toss.
Each result is generated using secure randomness directly on your device.
Your flip results stay on your device. CoinFlipTool does not require an account, and your flip history is not sent to our servers. Every flip is independent, meaning previous outcomes never affect what comes next — just like a real coin.
For additional transparency, CoinFlipTool also includes Provably Fair Mode, adding a verifiable layer of randomness using a public randomness beacon.

A real coin gives you one result.
