Hey everyone! 👋

While building cross-platform mobile apps with React Native, I realized how much time goes into setting up repetitive boilerplate code—things like secure local storage, biometric authentication, intruder capture layouts, and clean paywall screens.

To solve this for my own workflow and speed up future projects, I built VaultScript. Here is a quick breakdown of how the architecture is set up:

Biometric Authentication: Integrated secure FaceID/Fingerprint login seamlessly.
Encrypted Local Storage: Storing sensitive notes and media securely on-device without leaking data.
Monetization Layer: Pre-built subscription paywall screens ready to plug into revenuecat or stripe.

If you're an indie developer looking to save weeks of development time on your next mobile app and want a production-ready template, you can check it out here:

Would love to hear your thoughts or how you handle local security in React Native!
