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.

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.
