## What is Stillvaro?

There are no timers, no streak pressure, and no score chasing. The experience stays focused on one thing: the next four digits.

It’s a gentle way to practice focus and repetition.
	•	Practice in 4 digit blocks, moving forward through the sequence
	•	Turn on Guidance Mode to highlight the next expected digit
	•	Use Up Next to choose exactly where to continue
	•	Set a preferred starting block for resets and launch
	•	Open Reference Peek to browse nearby digits in the sequence
	•	Track your session with a quiet visual field and simple stats

Stillvaro is designed for steady attention, not pressure.

Version 1.0 Notes
Initial release with ring input, Up Next, Reference Peek, onboarding, stats, and an accessibility focused interaction.
