Description by Matthew Billman Written by the developer, not by AppBrain. Click to read.
GM10 is the social platform for everything trading cards. We’re collectors who have built a collector-focused application that connects the trading cared hobby by bringing the best of everything into one platform. These collector-focused tools include:

- We’re community first, our goal is to showcase the best parts of the hobby by being the primary place for members of the community to engage with one another, learn more about the hobby with breaking news and interact with the community by posting about it.

- The generation gap in trading is real, with our fun and nostalgic design, we’re looking to engage those young and old from wherever you call home in one place, you can even find out where the nearest upcoming show is going down so you can better bridge that divide.

- Being community-first always, everyone on GM10 has a profile that they can create to help put a face/avatar to the name. We hope both parties on a deal can learn about each other’s interests, where they call home, their collection and even their previous transactions.

- Say so-long to only having two options on an online marketplace, you can buy and sell your cards online with just a few clicks.

- Come break with us, we’ve developed an in-application randomizer that takes the pain away from your breaks.

- GM10 unlocks the next level of collecting by enabling you to make collectibles your business. With a sleek marketplace that is designed with the collector in mind we hope you’ll have a very profitable experience on the app for years to come

- We’ve dedicated a significant amount of our development to building out Brand Shops, you can establish your own shop where you and your friends/business partners can collaborate to sell your own branded merchandise or products to the broader market.

We hope you will join us and help build the community as we all look to slab it, stream it, sell it.
