⚠︎ Launch the app via start-cohen.command
This page is opened from the file system (file://),
which blocks the browser features this app needs:
- Firefox can't share your login between pages, so you bounce back to this screen.
- Chrome & Safari silently disable precise GPS, so the location is wrong.
- Android can't open
.command files — use a phone-side HTTP server.
To start the app correctly:
- Close this browser tab.
- In Finder, open the app folder and double-click
start-cohen.command.
- A terminal window opens and your browser will launch at
http://localhost:8787/login.html automatically.
- Keep that terminal open while you use the app — closing it stops the local server.
Nothing is sent to the public internet — the app still runs entirely on your Mac. The local
HTTP server just lets the browser treat the app as a proper website so GPS, login, and
time-sync all work.
