As a Temple 2023 graduate, I'm really passionate about being part of the Temple alumni community and showing the creativity and ambition that my experience there helped bring out of me.
Temple taught me more than just what I needed to become a pharmacist. It pushed me to think independently, solve problems, and be willing to build something of my own.
That mindset eventually helped me create Broad Street - the Wall Street of cards, a platform designed to make trading card collecting and investing simpler, more transparent, and more accessible.
Just 13 days after launching, we've already crossed 500 users.
I'm proud to be a Temple alum and proud to show that the foundation you build there can lead you in directions you may have never expected.

Scanned this 2019 Japanese Umbreon & Darkrai GX and BroadStreet matched the exact card, grading company, and grade at 100% confidence.
Current estimated value: $169.91
1-year change: +$55.41 (+48.4%)
This is exactly what I want BroadStreet to make easy—scan a card, instantly identify it, see its value, and track how it moves over time.
Would you hold this one or sell after a 48% run?

I'm a solo developer and I've been building this because every scanning app I tried would tell me a card was worth some number that no human being has ever actually paid.
So I built Broad Street: Card Scanner. You scan a card - raw or slabbed, one at a time or a whole page of 9 - and it shows you what that card has actually been selling for.
Then you tap PSA 10, PSA 9, PSA 8 and see the graded prices next to the raw price, so "is this worth submitting?" takes about five seconds standing at your kitchen table.
The thing I care most about: the prices are from real sold sales, and the app refuses to fake it. If a card doesn't have enough sales history to honestly compute a 7-day change, it shows nothing instead of making up a percentage. l'a rather show you a blank than lie to you.
(Also, tap the card on its detail page - it flips over, and the back is a stat block of your copy. Collectors seem to like that one. And when you've scanned a stack, one tap exports the whole thing as a priced PDF binder sheet - total value at the top. There's a Market tab for the day's movers too.)
It's free. No subscription, no paywall. iOS only for now.
What I'm asking: scan your weirdest stuff. Junk wax Donruss, 90s inserts, obscure Bowman parallels, off-brand slabs, whatever. When it gets something wrong - and it will - comment or DM me the card. I report data errors upstream and they get fixed fast (last one was fixed same-day). You'd be making the tool better for everyone.
Link in comments. Be brutal, I can take it.

Pulled this 2026 Topps Chrome JJ Wetherholt Aqua Refractor Auto /199 and I’m trying to decide whether it’s worth sending to PSA.
Would you grade this or keep it raw?
If you think I should grade it, what grade would you realistically expect from what you can see in the photos? I’d mainly be grading for value/resale rather than PC.

I released my app, Broad Street: Card Scanner, a little over a week ago, and I’ve been experimenting with different platforms to figure out where the most engaged users come from.
So far I’ve tried Reddit, TikTok, X, Instagram, and Apple Search Ads. I’ve tested them on different days, and Reddit has consistently outperformed everything else—not just in downloads, but in users who actually sign up, scan cards, and continue using the app.
What surprised me most is that Reddit traffic seems much more intentional. People aren’t just clicking and downloading, they’re actually trying the product and giving feedback.
For other indie developers, has Reddit been your strongest source of active users too? And what other platforms have worked well for getting actual users rather than just installs?
