I built Twinle to make exchanging social profiles as easy as scanning a QR code

I've always found it awkward meeting someone new and then spending a few minutes asking for Instagram, WhatsApp, LinkedIn, Telegram, and other usernames. It felt like there should be a faster way.

So I spent the last few months building Twinle.

The idea is simple: create one QR code that lets people instantly access the social profiles and contact information you've chosen to share.

Current features:

• 📱 Exchange contacts with a single QR scan
• 🔄 Two-way "Twinle Exchange" where both people connect instantly
• 🌐 Supports 10+ platforms including Instagram, WhatsApp, Telegram, X, LinkedIn, Snapchat, and Discord
• 🔒 Privacy controls so you decide exactly what information is visible

The app is now live on Google Play:

I'm looking for honest feedback from builders and users.

• Would you use something like this?
• What's the biggest weakness in the idea?
• What feature would make it genuinely useful for you?

I'd really appreciate any feedback—good or bad. Thanks!
