Running on a Real Device

This week CalmSpace moved from Android Studio to my actual phone.

Previously, the app was running in the development environment. The masking system functioned there, and I was able to test core logic. But running in a simulator is different from running on real hardware.

Now the app is live on my device, and I successfully integrated the masking model I built last week directly into the mobile build.

That was the real milestone.

From Model to Implementation

Last week I focused heavily on building the masking system itself. This week was about integration.

The noise generation works.
The masking responds to ambient sound.
The system runs directly on my phone.

There are still issues. Some of the instability from last week carried over. Audio behavior is not perfectly consistent yet, and performance tuning still needs work. But the full loop is operational outside the development environment.

That is a meaningful step forward.

Building audio software is very different from building static apps. Timing, buffering, permissions, and hardware interaction all matter. Moving from Android Studio to a physical device exposed new edge cases, but that is expected. Real testing reveals real problems.

And that is exactly where progress happens.

What Still Needs Work

The masking is functional, but not fully stable. I need to:

Improve consistency across longer sessions
Refine how the system reacts to changing noise levels
Optimize performance to prevent small glitches

This is now refinement, not experimentation.

The system works. Now it needs to become reliable.

Next Week Focus

Next week I will shift attention to two areas.

First, UI and UX refinement. The structure is complete, but the experience needs polish. CalmSpace is meant to feel quiet and supportive, so the interface needs to reflect that intention.

Second, headphone integration. Since the app depends on audio delivery, testing across wired and wireless headphones is critical. Masking has to work in real world sleep setups, not just in ideal conditions.

Where CalmSpace Stands

CalmSpace now:

Runs on a physical phone
Integrates a working masking model
Generates responsive noise
Has full MVP screen architecture

It is no longer just a concept or a prototype inside a simulator. It is running on real hardware.

There is still work ahead. Backend systems need deeper integration. Audio stability needs improvement. UI needs refinement.

But the foundation is real.

And that changes everything.
