TimeGauge turns the day, the month, the year, a custom deadline, and — if you opt in — your estimated remaining lifespan into thin progress bars that sit permanently in the menu bar, no click required to see them. It’s a native, sandboxed Swift app with zero tracking and a $5.99 lifetime license, not a subscription. Underneath the memento-mori framing it’s just a genuinely glanceable countdown widget.
