🌬️ Introducing Glyph Zen: Guided Breathing with Nothing Phone Glyphs 🌬️

Hey everyone!

I wanted to share something I’ve been quietly working on: Glyph Zen—a personal project that started as a challenge to see if I could program an Android app.

What is Glyph Zen?

Glyph Zen uses the Glyph Interface on Nothing Phone 1 & 2 to guide you through breathing exercises. Here’s how it works:

2 Breathing Techniques:

🟦 Box Breathing

🟪 4-7-8 Breathing

How it works:

Start a session, turn your phone over, and follow the Glyphs:

Steady brightness: Hold your breath
Increasing brightness: Inhale
Decreasing brightness: Exhale

A countdown gives you time to turn your phone over.

A gear animation gives you a subtle hint at cycle changes with a cycle counter below.

Features So Far

Nothing Phone 1 & 2 support (NP1 needs some tweaks for Glyphs)
Font switching: NType & NDot
Custom light/dark modes and 4 unique themes (resettable to default)
Developer settings page (mostly placeholders for now)
LED calibration testing (NP2 only at the moment)
Logging: Toggle logging, save/send logs (off by default)
Modal pop-up dialogs: Only interactable via buttons, disables background touch
Custom morphing toggle buttons throughout the UI
Cancel button: Instantly stops the Glyph animation

What’s Next?

There’s still a bit to polish and add, but I’m incredibly proud of how far it’s come. For now, I’m focused on getting it running perfectly on both NP1 and NP2.

No public release or source code planned (despite what the settings card says)—just wanted to share the journey and maybe get some feedback from the community!

It all started as a challenge to myself—could I build an Android app that actually integrates with the Nothing Phone’s Glyphs? I’d never done anything like this before, and honestly, I wasn’t sure I could pull it off.

But once I got the basics working, I got obsessed with making it look and feel great. The first version technically worked, but I wasn’t happy with the UI at all. So I dove back in and rewrote the whole thing using Jetpack Compose.
