I love ALT

Easy to use 🔥

Hmm

Great for comps but recently tapping between different grades doesn’t work and comps aren’t coming up. Strange!

Atl

Very good

Worst Auction house in the business

Absolute disaster of a place. You will lose thousands of dollars by sending your cards to them. I advise anyone and everyone to not do so. I had offers for my cards twice as much as what my cards sold for at their auction. I was convinced to do so by their vip rep whom i met at a card show. Biggest mistake i’ve ever made. DO NOT USE ALT TO AUCTION YOUR CARDS! only use them to buy as you’ll be able to literally steal them. Absolute Joke of a place.

Best Auction House of 2026

ALT has everything you want from an auction house and nothing you don’t. Fast and reliable service and seller friendly support make it a breeze to list on ALT. This will be my “go-to” auction site from now on!

Decent

Half the time doesnt load any comps and recent comps take a while to post

Awesome app

Much needed app for a collector

Please add TAG 🙏

Great app in all aspects and their commitment to continually improve. Just can’t give it a 5 star until they can add TAG grading to the scanning function as well! (Please add soon TAG customer service :D)

Alt is a must

Guys, this has literally been the best experience across all platforms. Fast, fair, and great communication. If you’re not using Alt, you gotta give it a try. Feels like the reach is only growing and marketing keeps getting better and better. Wish I would have given this a shot sooner but glad I’m here now! Hope to land some bigger cards in the future to see just how far this thing can go. Thanks to all the Alt team for their professionalism and user friendly app.

Do not know how to take a photo when it says take a photo when you scan it!

Not great

Language filter

Crazy how this app doesnt have a language filter. So tired of looking up a card and i see 10 sales of the same Japanese card.

4 stars

It’s great I just don’t like how it doesn’t do raw cards

Best free app to comp cards

Genuinely the best free app to comp cards. Some things they’re better at than paid ones. Showing current listing is very nice. I wish I could compare or search multiple cards like a tab.

So bad

I sold cards and they lost them terrible

Be aware

Please don’t use this app if you grade cards yourself, you will lose money. I wasn’t aware that bids start so low and I’m unable to pull my submitted cards from auction. Unless you have cards worth thousands, stay away from this app and use eBay instead.

Updates

Updates every single day are incredibly annoying. There shouldn’t be this many “bugs”, and updates alone.

Get better auctions

The auctions are silly it says it ends at 9 but 10 to 12 hours later at finally end fix THE GLITCH ALT IT IS SO BAD FIX IT NOW IN THE NEXT UPDATE OR MAKE THE AUCTIONS LONGER

Not working as good as it used to be

Doesn’t pick up recent sales as much as it used to

App is great butt

They need to add more than just psa,bgs, cgc. We need tag and others added!

Lost psa cards

Sent to 5 of my psa graded cards worth $2500 to $3500 on a good day be auctioned off and they didn’t make it, but I take screenshots of everything and usps says they misdelivered them but they suck helping after I used there shipping label and there insurance
