NoteKar v7.4.0 - The sovereign existential compass & chronometer craft for Android

Hey Product Hunt! 👋

A while ago, I introduced NoteKar here as an offline, one-tap timestamp logger.

Today, after countless iterations, feedback cycles, and rebuilds, I’m releasing NoteKar v7.4.0 - the definitive, feature-complete release that transforms NoteKar from a minimalist clicker into a sovereign existential compass.

### 💡 The Big Shift: Confronting "The Cost of the Void"

Most productivity apps ask you to organize endless to-do lists or track abstract minutes. But time doesn't wait for to-do lists; if you aren’t actively conscious of your hours, they vanish.

In v7.4.0, NoteKar introduces the Life Audit Engine:

Every 24 hours is mathematically partitioned:

`24h = Sleep + Logistics (Food/Commute) + Conscious Window`

Any conscious hour not accounted for in deliberate focus sessions is calculated as the Unaccounted Void. Across 6 temporal horizons (Today, Weekly, Monthly, 45-day Habit Window, 180-day Half-Year, and 365-day Planetary Year), NoteKar calculates visceral metrics like Conscious Waking Days Lost and your Intentionality Ratio. It's an existential mirror inspired by Seneca: "Time is the only thing where it is a virtue to be greedy."
