CSGO Trade up Library Free

An App to see all Skin Collections of CSGO in a few clicks.
UPDATES will follow for every new coming CSGO COLLECTION!
(Version 1.0 - All skins to Falchion Collection).
What's the point of this app? - Imagine you want to trade up to a "AWP | Asiimov" but you don't own any skin out of it's collection. You can't see what purple skins you need for your trade up, to have the chance for the AWP.
With this app you don't have to take a look for skins at the steam market anymore!
