Questions, answered.

Press the global hotkey from any app and a borderless input opens. Type the task in plain language and Rumline's parser sorts out the details for you — for example:

Call Geoffrey #bikeshop tomorrow

Use #shorthand to assign a project, natural-language dates like tomorrow or next Friday, and priority cues. No fields to click — hit return and it's filed against the right project.

Health is computed, never set by hand. Every project sits in one of three bands based on workload and time since your last touchpoint:

Critical — overdue tasks, or a client gone quiet past your cadence. Needs you now.
Monitor — approaching the cadence cliff or workload climbing. Watch the drift.
Healthy — fresh contact and a manageable load. Earned its calm.

Rumline always shows the cause alongside the band, so a project is never just "red" — it's "red because four open tasks and last contact twenty-one days ago."

Each morning Rumline composes a short paragraph naming the day's actual focus — overdue work first, critical projects second, today's commitments third. It ends with the single thing that, done today, would matter most. It's generated on-device by default, so it stays private.

Paste your call notes or a meeting transcript, pick the project, and Rumline extracts the action items as draft tasks. You review and edit them before anything is saved — nothing lands in your system without your sign-off.

The name comes from rhumb line — a sailing term for a path that holds a steady compass bearing all the way to its destination. Rather than constantly recalculating the "perfect" route, you pick a heading and stay on it.

That's the idea behind the app. With a lot of clients pulling in different directions, Rumline helps you hold a steady heading — show up where you're needed, keep moving, and not get knocked off course.
