by

AureaCam is a web tool that turns your camera into a photo composition coach. It applies the rule of thirds and golden ratio in real-time, scoring your shot from 0 to 100 as you frame it. Perfect for beginner photographers who want to improve without reading manuals. It's a PWA, so no installation is required. Available in English and Spanish.

Hi everyone! I'm Franco, a self-taught full-stack developer from Bolivia. I built AureaCam because I've always struggled with photo composition – I knew about the rule of thirds and the golden ratio, but putting them into practice while shooting was always confusing. So I created a tool that does exactly what I needed: a camera that gives you real-time feedback on your composition, scoring from 0 to 100 as you frame your shot. It's like having a photography coach in your pocket. AureaCam is a Progressive Web App – no downloads, no installations. Just open the link, allow camera access, and start practicing. It works on both mobile and desktop, and it's available in English and Spanish. The demo is completely free, so you can try it out and see if it helps you improve your photography. I'd love to hear your feedback – what score did you get? What features would you like to see next? Thanks for checking it out!

nice idea, rule of thirds is one of those things that's easy to explain but hard to actually feel while framing a shot. since it needs camera access in the browser, is the scoring happening on-device or does it send frames to a server? would want to know before pointing it at anything private

 Hi! Great question – and I completely understand the concern.

To be upfront: all image processing runs 100% on-device. The camera feed never leaves your browser. All the scoring – rule of thirds, golden ratio, symmetry, and lighting – is calculated locally in JavaScript using your device's camera stream. No frames are sent to any server.

Now, about the login: the email and password are only used to verify if the user has purchased the full version. It's a simple license check to prevent piracy and ensure that only paying users access the complete features. No personal data is collected, stored, or shared – and you can use the demo freely without any login at all.

So: demo = no login needed. Full version = quick license verification, and that's it.

The app is designed with privacy and simplicity in mind – no tracking, no data collection, just a tool to help you learn photography.

Feel free to test the demo with confidence – your privacy is respected. 😊

Let me know if you have any other questions!

Best,
Franco

 that's exactly what I was hoping to hear, on-device only makes this way easier to recommend. one follow up - is the license check a one time thing per install, or does it ping on every launch? asking because that's usually where a "no server calls" claim quietly breaks down

Maker

 My honest answer to your question:

Right now, it does ping on every launch – but only for a quick license check, not for any camera data. And I'm already working on a fully offline alternative that will remove even that single call.

So: on-device processing is already 100% real. The full offline license check will make it even better.

I hope that answers your concern – and I genuinely appreciate you asking. This kind of feedback helps me build a better, more private product.

Let me know if you have any other technical questions – happy to dig deeper.

Best,
Franco

 The improvement I'm working on (for the next update):

I'm moving to a token-based offline verification system:

  • When a user purchases the app, a cryptographically signed license token is generated.

  • That token is stored locally on the device (in the browser's local storage).

  • On each launch, the app checks the token locally – no server call needed.

  • The token validates the purchase and the expiration (if any) without ever contacting the server.

This way:

No server calls at all after the initial token generation.

No email/password stored or transmitted.

Completely offline license verification.
