When a coin flip decides for you

Two options, zero stakes high enough to deserve debate — a flip ends the loop. The hidden value is that a fair coin does not just pick; it makes you reveal which answer you were secretly hoping for by the time you open your eyes.

A fair coin when you can't decide

Tailsnow gives you a genuinely random coin flip the moment you need one. It's for anyone stuck between two options—where to eat, who goes first, whether to commit or wait—and tired of overthinking. No login, no settings, no bias creeping in. You land on the page, the coin is ready, and the result speaks for itself. Use it solo to break a mental tie or share the outcome with a group so everyone agrees the call was fair.

One click to a clean result

  1. Land on the page and confirm you see the coin ready to flip.
  2. Click the coin or the flip button to trigger the toss.
  3. Watch the animation spin through heads and tails.
  4. Read the final result displayed once the coin settles.
  5. Flip again as many times as you need another outcome.

Frequently Asked Questions

Does it keep a history of flips?

Yes. Every result is added to the live tally so you can watch the running counts and check that the distribution stays fair.

It is free, works on any device, and needs no app or sign-up.
