this app is very frustrating. It updates to much and never fixes the issue. I have a cash advance to accept which it keeps giving me an error that I can't get the swipe. You have 48 hours to reply or offer is declined they already have my cards, no one has gave me any answers or insight on what to do about the cash advance or why the charge of fees were being processed before I even accepted the advance.

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.
