The problem

You already know exactly who it is.

The friend who's "so in" on Thursday and evaporates by Friday. Every crew has one. Until now, they've been getting away with it — because nobody kept the receipts.

WhoFlopped keeps the receipts.

How it works

Three steps to the truth.

1 Log the hang

Create an event — dinner, movie night, that hike everyone swore they'd do — and invite your crew.

2 Take attendance

Mark who showed up, who flopped, and who had a genuinely good excuse. (We'll allow it.)

3 Watch the rankings

Everyone gets a flop rate and a reputation tier. No arguments — just data.

Reputation tiers

Where does your crew land?

Everyone earns a tier. Nobody gets to pick their own.

Rock Solid Would help you move. Twice.

Reliable Says yes, means yes.

Usually Shows A no-show is breaking news.

Occasionally Flops There's… a pattern forming.

Coin Flip Genuinely 50/50. Thrilling.

Slippery Confirms fast. Vanishes faster.

Houdini Last seen: "omw".

👑 Certified Flopper A legend. For the wrong reasons.

The fine print

It's a roast, not a record.

Your flop rate is only visible to your friends. No public profiles, no strangers, no permanent file — just the inside joke your group chat has been keeping score of anyway.

Friends only Private by default Roasts behaviour, not people

Someone in your group chat needs this. It might be you.

Receipts for every "Sorry, can't make it." Be first in line when WhoFlopped drops.
