Draw your time. Focus till it's gone.
Tap the i button, top right, for full instructions.
Instead of a countdown circle, you draw a line. Its length becomes your focus time. As the timer counts down, the line erases from the far end, back toward where you started.
Click or touch and drag to draw. You can let go and start again anywhere — LineDoro connects the two strokes with a straight line, so it's still one continuous line. The line is capped at 3× your screen width. Stop early and hit Start whenever you're happy with it — you don't need to reach the cap.
Small dots mark 25%, 50%, 75%, and 100% along your line, with a "Start" label at the beginning. As time runs out, each checkpoint disappears once the line erases past it — a built-in progress readout.
Color, line style, thickness, background traces, focus/break length, and cycles are all set on the draw screen itself — no popups. Once you hit Start, that whole bar disappears and the run screen takes over.
Smooth, Jagged, Dashed, Textured, and Paintbrush (which also gives you a little brush cursor while you draw).
Faint Nature, City, Abstract, Ocean, or Space line-art appears behind the canvas so you have something to outline if you're not sure what to draw.
Pause/Resume, Redraw (go back and draw a new line for the current phase), Skip phase, or End session — all on the run screen.
You focused for 100 minutes across 4 cycles.
