CYKI — Sneaker Portfolio

Know what your collection is actually worth.

CYKI is the sneaker portfolio tracker for collectors who want more than a shoebox full of receipts. Catalog every pair you own and watch its live resale value update daily. No spreadsheets, no guesswork.

LIVE MARKET VALUES & P&L
Every pair is priced against real resale market data, updated daily. See your total collection value, cost basis, and profit or loss at a glance — per pair or across your whole rack.

THE CYKI 100
The only index built for the sneaker resale market. Track how the market is actually moving, then see how your own collection stacks up against it. Beating the index is the flex worth screenshotting.

PRICE ALERTS
Set a target price on any pair and track it against the live market, so you know the moment your grail finally moves. No more checking five different apps.

GRAILS & WATCHLIST
Track the pairs you do not own yet. Keep a running watchlist of grails, and when you finally cop one, bring it straight into your collection.

BEAT THE MARKET
Pick a basket of five sneakers and compete against the CYKI 100 all season. Every two weeks a themed event rotates the challenge — Jordan only, under $200, Adidas, New Balance, and more — so there is always a new game running alongside the monthly season.

Built by collectors, for collectors. Not investment advice — just an honest read on what's in your rack.
