Beta testers

You're in. Here's how to start.

The beta runs on TestFlight, Apple's own app for trying apps before they reach the App Store. It takes about two minutes, and it's free.

  1. Open your invite link on your iPhone

    It's in the email titled "You're in: the Stud Stacks beta". Open it on the iPhone you want to use, not on a computer.

  2. Install TestFlight

    The link takes you to Apple's TestFlight page. If you don't have TestFlight yet, tap to get it from the App Store, then go back to the email and tap the invite link again.

  3. Accept, then Install

    In TestFlight, tap Accept, then Install. Stud Stacks appears on your home screen with a small orange dot next to its name, which means it's a beta.

  4. Make your account

    Open Stud Stacks, sign up with your email and a password, and tap the link in the verification email we send you.

  5. Add some LEGO

    Start with a few things you know well, so you can tell whether we get them right:

    • Scan a barcode on a set box, or search a set number.
    • Photograph a minifigure on a plain background, or a whole tray at once with Multi scan.
    • Look at each price, how many sales it's based on, and whether that matches what you'd expect.

Tell us what's wrong

This is what the beta is for. Rough notes are perfect: "this price looks too high", "it couldn't find my figure", "I didn't get what this button does".

Three ways to send feedback

  • In the app: Settings, then "Tell us what's wrong". It goes straight to Freddy.
  • On a wrong scan: tap "Something wrong with this result?" under it and pick what went wrong. This one helps most, because it sends us the scan too.
  • Screenshot anything odd: take a screenshot, tap the preview that pops up, then Share Beta Feedback. Add a line about what you expected.

Or just reply to any of our emails.

Good to know

The app looks out of date after an update

Small updates download in the background. Close Stud Stacks fully (swipe it away in the app switcher), open it, wait ten seconds, then close and open it once more. Bigger updates come through TestFlight: turn on Automatic Updates in TestFlight so you always have the latest build.

TestFlight says the build has expired

Apple expires each beta build after 90 days. Open TestFlight and install the newest build; your account and collection are kept on our server, so nothing is lost.

Is it free?

Yes, completely, during the beta and early access.

I'm on Android

The beta is iPhone only for now. If you joined the waitlist as Android, you'll hear from us as soon as there's an Android build.

The invite link doesn't work

Make sure you're opening it on an iPhone with TestFlight installed. If it says the beta is full or not accepting testers, email support@studstacks.app and we'll sort it out.

How do I leave the beta?

Delete the app, or open TestFlight, choose Stud Stacks and tap Stop Testing. To delete your account and data too, use Delete account in the app's Settings first.
