About CYKI
CYKI is a sneaker portfolio tracker: collectors see what their collection is worth, live, and how it is doing against the market.
What CYKI is
CYKI (“Can You Kicks It”) is a free app for iOS and Android. Catalog every pair you own, see its live resale value, track profit and loss against what you paid the way you would a stock portfolio, and set price alerts.
CYKI also publishes the CYKI 100, a daily index of the sneaker resale market built from aggregated marketplace data, alongside brand indices tracked the same way. How values and the index are calculated, including the limits of the data, is explained on the methodology page. The Market, the blog and the videos are where that data is put to use.
Who is behind it
CYKI is published by Can You Kicks It, a solo studio based in Denmark, founded by Klaas Hermans. The app launched on Google Play and the App Store on 26 August 2026.
