These packages are placeholders. douu is a concept build: the files below are correctly named and correctly sized prototypes that demonstrate the download flow. They do not install anything and contain no executable code. The SHA-256 on this page is the real digest of the placeholder file.

Mobile

The remote control.

Text the crew from the train. The phone app holds the thread, the approvals and the log; the work still happens on your desk.

First run

What happens after you install.

1. It looks around

douu asks which folders it may read. Say no to all of them and it still works — just with less context.

2. Connect three apps

Mail, calendar and files. Everything else can wait until a job needs it.

3. Pair your phone

One scan of a code and the thread is on your phone. Unpair from either side.

4. Hand over a job

Start with something you would describe in one sentence. Watch the log the first time.
