WIP. GitHub heatmap meets Apple Reminders — on your Mac menu bar and as an iPhone widget.
Level 2 completed.

Why
When you check something off in Apple Reminders, that item is fully gone — no trace, no history, no sense of what you accomplished. I built ZenMinder because I wanted that feeling back: a visible record of what I got done, day by day.
What
ZenMinder turns your Apple Reminders history into a GitHub-style contribution graph. Filter by all, completed, or created reminders. Tap any day to see what you got done — or what you added.
I started building this as Reminder Chart and renamed it ZenMinder as it took shape.
Mac menu bar
On Mac, ZenMinder lives in your menu bar. One click opens the heatmap — months of reminder activity at a glance, with a detail view for any day you select.
iPhone widget
On iPhone, the same heatmap works as a home screen widget. Tap a day to drill into completed or created reminders — same graph, pocket-sized.
