[DEV] Neruppu: Rebuilding "Haven" from the ground up for modern Android 🔥

Hey everyone,

Like many of you, I loved the concept of Haven (the app that turns your phone into a physical security guardian), but the original project hasn't seen an update in years and struggles on modern Android versions.

I’ve spent the last few days rebuilding the concept from scratch. It’s called Neruppu (Tamil for Fire). It’s a complete rewrite aimed at being a lightweight, modern, and privacy-first security tool.

Why Neruppu?

Modern SDK Support: Built for modern Android (no more legacy crashes).

Privacy First: 100% Open Source and works entirely offline.

Optimized Performance: Focusing on battery efficiency so your "guardian" device lasts longer.

Lightweight: Stripping out the bloat to focus on core sensor reliability.

I need your help!

I’m looking for the community’s help to turn this into a stable, go-to tool for the FOSS community:

Code Review: I’d love for some experienced Android devs to peek at the repo and tell me where I can optimize.

Contributors: Whether it’s UI/UX, localization, or core features (like Signal/Telegram integration), PRs are very welcome!

Feedback: What did the original Haven get wrong? What’s the one feature you need for a "guardian" device?

Supporting the Project

As an independent developer, I’m committed to keeping this project ad-free and open source. If you believe in the mission of keeping privacy tools alive and want to help speed up development:

Star the Repo: It costs $0 and helps others find the project!

Financial Support: If you’d like to help cover testing devices or server costs for future encrypted sync features, you can support me.

Repo Link: https://github.com/thamizh-root/neruppu

I'll be hanging out in the comments to answer questions and take suggestions. Thanks for checking it out!

Hello everyone,

I’ve always admired the Haven: Keep Watch project (Guardian Project). It’s a brilliant piece of privacy tech, but unfortunately, it hasn't seen much activity lately and has compatibility issues with modern Android versions.

I’ve decided to build a version from scratch to bring it back to life.

My Background & The "Vibe Coding" Challenge

I’m a Project Manager by day and a Full-Stack Dev (Node.js, React, React Native, Postgres) by night. However, Kotlin is my blind spot. I’ve been building this so far using the Android Studio AI Agent (Gemini).

It’s been a wild ride of "vibe coding," but as many of you know, AI agents can sometimes overcomplicate simple Android lifecycles or miss fundamental Kotlin best practices.

Why I’m Looking for You

I’m looking for a collaborator or mentor who actually knows the "Android Way." If you love Kotlin and believe in open-source privacy tools, I’d love to have you on board.

The Goal: A modern, stable, MIT-licensed version of Haven.

The Tech: CameraX, Sensor APIs, and eventually my own version of iohook.

The Vibe: Collaborative, open-source, and mission-driven.

What if nobody steps up?

I’ll keep pushing forward with the AI agent and my own research, improving it bit by bit. But having someone who can say, "Hey, don't do it that way, use a Flow here instead," would be a game-changer.
