With Maru

Maru changes with whatever you’re doing.

Maru scribbles along when you write, settles down when you focus, and celebrates for a moment when you check something off.

Write

Capture a thought before it slips away.

No need to look for a save button. Mix text and to-dos in the same note, and Tobomi saves when you pause.
