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.

This update brings iPhone up to date with everything added since launch, plus what's new this week.
NEW — SEE YOUR COLLECTION AGAINST THE MARKET
Your vault now plots against the CYKI 100, our daily index of the sneaker resale market, so you can see whether your collection is beating the market or trailing it.
CONDITION NOW COUNTS
Grade a pair and its condition counts everywhere — the pair's own value, your collection total, your profit and loss, and the leaderboards. Tap your collection total to see how it works. Adding a pair now asks for its condition.
WHERE YOUR PAIR'S VALUE COMES FROM
Open any pair and the market value now explains itself in plain language — priced from recent sales in your size, from sales of other sizes when yours hasn't sold, or from current asking prices when there are no sales at all. If there's no market for a pair right now, it says that too.
We also rebuilt the labels on that screen, because it wasn't clear which number was your pair's actual worth:
• "Current value" is now "Market value", matching the top of the screen — same number, one name.
• "Market avg" is now "Avg asking price", because it averages what people are asking, not what pairs sold for.
• "All-time high" and "All-time low" are now a single "Asking prices, all sizes" range. They were never a historical high or low — they show what's being asked right now.
• We removed a row that showed your pair's value a second time under a different name.
TRENDING, REBUILT
The Trending tab has been reorganised so the leaderboard and biggest movers are visible without scrolling, with a new Drops Worth Watching section.
NOTIFICATIONS THAT ARRIVE WHILE YOU'RE IN THE APP
Price alerts and milestones now show up immediately instead of waiting until you next open CYKI.
PRIVACY
Sign in with Apple no longer requests your name. We never used it, so we stopped asking for it.
ALSO FIXED
• Drop dates showed a day late in some time zones
• Duplicate sneakers in catalog search
• A loss could display with a double minus sign
• Search results now lead with the release year
