Realtime sprint estimation

Estimate stories with cards your team actually wants to play.

Deal a Fibonacci hand, everyone picks in secret, the host flips the table. Share one link and guests join instantly — no account required.

Guests only need the link you share.

How it works

Three moves per story. That's the whole ritual.

  1. 1

    Deal the hand

    Create a session, pick your deck, share the link.

  2. 2

    Pick in secret

    Everyone chooses a card — votes stay hidden server-side.

  3. 3

    Flip the table

    The host reveals, you see spread and consensus instantly.

Everything a refinement needs

And nothing that slows the room down.

Realtime, no refresh

Votes and reveals land for everyone the moment they happen.

Guests join by link

A name is all it takes — no accounts, no invites to chase.

Host controls

Reveal, reset, rename, run the round timer, close the session.

Observer mode

Facilitate without voting so your number never skews the room.

Fibonacci decks

Classic or modified Fibonacci, chosen per session.

Consensus at a glance

Average, spread and agreement summarised after every reveal.

The reveal moment

Everyone flips at once, so nobody anchors on the loudest voice in the room.

Median 5 · Spread 3–8 · discuss the outlier.
