I can’t even create an account, because it keeps saying that it couldn’t send the verification code to either of my 2 phone numbers! Tried multiple times. Seems like garbage, I really hope not. It seemed like the perfect app for me. If I don’t get a response, or an immediate update, I’ll have my answer. ### 2/5 — It won’t work *2025-01-22* It won’t send the code to my phone number. ### 5/5 — I love this app *2024-12-27* I was using this app until my skibidy parents mewed and had no jawline after that they hawk tuahed on that thang afterwords they lost their edging streak WHILE USING THIS APPP (so please delete this) ### 1/5 — Impossible to use *2024-12-05, version 4.11* What’s the deal with these apps that treat security like Fort Knox. I’ve been cycling through verifications and resetting for 15 minutes. I give up. Not worth it. ### 5/5 — Get this app! *2024-06-07* It is very cool to sell and look at cards. I’ve sold a couple cards and bought some, it’s nice to meet new people. ### 5/5 — 👍🏻 *2024-06-07, version 4.7* Very good app for sports cards! ### 1/5 — Scammers *2024-03-23* Downloaded this app just for my personal collection and someone was interested in a card. I'm not opposed completely to selling. Guy tried to scam us through Apple Pay, after I got fraud alerts and declined transaction, all of a sudden he stops talking and reading messages. ### 1/5 — No good on iPhone *2023-12-05, version 4.3* Can’t adjust zoom on the iPhone ! App is pointless ! Can’t scan cards, blurry on brand new iPhone ! No adjustments available !! How is someone supposed to use the app !!!!! Lame ### 5/5 — Loving the app!!! *2023-11-29* Great way to organize a collection, interaction with others, and the ability to see comps directly at 130 point!!! Awesome app!!! Only glitch and see is that sometimes a card appears on my collection twice. ### 5/5 — Comp Prices *2023-10-27* What happened to the app. It will not let you check comps for the card anymore since the update happened. ## Frequently asked questions about NextGem ### What can I do with NextGem?
