About
MindStem on iPhone is the capture door: one field, one Save.
A thought arrives mid-walk — type it, save it, forget it. It travels through your own iCloud and lands in the Brainstorm tray of the map open in MindStem on your Mac. Thoughts wait visibly until your Mac picks them up, and you can take one back before it goes.
Capture from anywhere: the app, Siri, the share sheet, or a Back Tap / Action Button shortcut ("Capture a Thought").
The maps themselves live in MindStem for Mac — brainstorm against the clock, structure by drag & drop, read your day on the clock, leave as Markdown or PDF. On iPhone, MindStem is deliberately small: capture, not cartography.
No account. No server. No tracking. Your thoughts travel only through your own iCloud.

What's New in MindStem
1.3.1
September 10, 2026
A thought travels the moment you save it. Fixed: a thought captured on iPhone could wait on the phone until the next save nudged it along. Every capture now announces itself to your iCloud as it lands, so it reaches the map on your Mac right away — and the waiting list clears just as promptly once your Mac picks it up. Thanks to the friend who caught this.
