For nostalgia-minded event lovers who are struggling with the extinction of physical ticket stubs, Turnstile is a new interactive online community that acts as a digital museum, providing users with a new way to document and share the detailed history of their ticket stub collections with other fans.
Whether it's a movie ticket, playoff game, or life-changing concert, every stub tells a story. With Turnstile, people from around the world are able to bring their beloved ticket stub collections back to life and share a small part of their personal history.
Turnstile is currently in early iOS beta testing via the Apple TestFlight. This version of the app lets you upload photos/screenshots of your printed or digital stubs, add custom event details, and link to digital "artifacts" from the event, like concert set lists, game highlights, or personal photos from your camera library. Everything you upload is local to your own device. You'll be asked to create a username so stubs and artifacts remain in the app as you come and go, but Turnstile does not get access to any of that information.
We're focused on building the core experience and would love your feedback!
If you'd like to be added to beta test, see instructions below.
Everything you need to know about this early stage version of Turnstile.
Email albert@turnstilestubs.com with your Apple ID username and download Apple TestFlight in the App store on your Apple device. We will then push the beta build of the app to your phone for download.
This version of Turnstile is fully local to your device. This means that all uploaded images, event details, and artifacts are stored only on your phone.
We use simple local storage (JSON) - no servers, no accounts. We do ask for a username to be created so that stubs and info that you add stay in the app as you come and go. At this stage, Turnstile does not have access to any of the information, images, or data that you input into the app.
At this stage, even if you select private or public when you create a username, all of your information will stay local to your phone. In later versions of Turnstile, you will have the option to curate a collection and keep it to yourself, or make it public to share with others, appear in the social "Tailgate" feed, link your stubs to your favorite teams, bands, and so much more.
Tailgate is a social feed for sharing your favorite stubs and stories. In beta, we've populated the feed with a couple of sample posts, and any stubs that you add will also appear in the feed (though no one else who has downloaded the app will see your stubs)

We're currently looking for technical co-founder or founding engineer. We have a full growth roadmap and revenue model that can be shared during a 1:1 meeting.
Please see job description below and reach out if you want to help build the future of fan memory.
Turnstile is a nostalgia-driven, early-stage startup built for collectors of live event memories — a mobile-first platform where users can upload ticket stubs, tag them with event details, and share memories, photos, and digital artifacts from the event.
It's part digital museum, part social time capsule for superfans of concerts, sports, movies, and more.
Turnstile was a runner-up in a 2023 innovation competition and has since evolved into a working mobile app. The current version, built in Flutter by a solo non-technical founder, is now live on TestFlight and includes the following features:
-Image capture and upload for physical ticket stubs
-Event detail entry and stub archiving
-Persistent local storage of all uploaded stubs and metadata
-Gallery view of saved stubs (“My Stubs”)
-Social feed feature ("Tailgate") with dummy posts and user posts as they upload stubs
-Bottom navigation bar with sections for Profile, Add Stub, and “Tailgate” feed(MVP version live)
-Support for attaching artifact links, choosing event type, and entering story captions
The app was intentionally built in Flutter for early-stage prototyping and beta testing.
We are fully open to a new technical direction and welcome your vision. As our Technical Cofounder, you’ll have the freedom to propose and implement a more scalable architecture, whether that means evolving the current Flutter build or transitioning to a new framework entirely.
Your leadership will shape the infrastructure and technology choices as we prepare for public launch and long-term growth.
-Built in Flutter (Dart) - current build running on iOS
-Distributed via Apple TestFlight to small group for beta testing
-Persistent stub storage implemented using local JSON storage
-Navigation, detail input, and image upload fully functional
-Initial UI/UX design in place with onboarding, username creation, gallery view, and grouping/filtering stubs by event type
Cloud-based storage and user accounts (e.g.,Firebase or Supabase)
-Social feed ("Tailgate") where users can share and explore public stubs
-OCR-based stub scanning and autofill of event data (name, date, location)
-Full growth plan and revenue modeling is complete and ready to share via 1:1 meeting
-App Store release by end of 2025, post-beta phase
