ALT needs a Pokemon ONLY mode. I just can't use this app. It is so cluttered with worthless sports card stuff that is of no concern to me. I don't want to buy anything and I definitely don't want any sports cards. CollectR is so much better how it just pops up to my collection and I only see what I care about. There are way too many wasted clicks, filters, sorting, etc. with all. Fixed that and I will be happy to change my review. Time is money and I can't waste time looking at useless stuff.

I like it for market data. It's mainly supposed to be a marketplace for graded trading cards, but doesn't seem a lot of people use it to post their cards. They're some, but more people using it would quickly improve that. It's best for looking up a specific card or player for market data. It tracks sales across platforms like ebay, myslabs, and several auction houses and gives you an average value based on card grade. Also, it shows each cards graded population across psa and beckett.

Doesn't show market price of listings, doesn't count in shipping price (or destination eligibility!), poor filtering (not even by language), no long-term price graph, and extremely slow to navigate with no concept of "caching data"
