Draw a flowchart, UML diagram or process map on your phone in minutes, then save it as an image, PDF or SVG you can actually find. No account, and no watermark on your exports.
DRAW WITHOUT FIGHTING THE SCREEN
• Tap + on any shape to add the next step, already connected
• Drag from one shape to another to draw a line, or tap the two shapes
• Straight, right-angle or curved connectors, with labels like "Yes" and "No"
• Shapes snap and line up with each other, and show their size and angle as you resize or rotate
• Align and distribute several shapes at once
• Undo and redo every step; your work saves itself, even if you switch apps
35 SHAPES
Flowchart symbols, basic shapes, notes, callouts and clouds. Pro adds UML, ER and BPMN libraries: actors, class boxes, packages, entities, gateways and events.
TEMPLATES THAT LOOK LIKE SOMETHING
Start from a flowchart, login flow, org chart, SWOT, Kanban board, roadmap, mind map, ER diagram, UML classes, BPMN process or network map. Every template shows a real preview before you open it.
TURN A LIST INTO A DIAGRAM
Type or paste an indented outline and get a tidy, laid-out diagram instantly.
MAKE IT YOURS
One tap restyles the whole diagram: nine themes including Midnight, Paper, Blueprint, Neon, Glass, Sunset, Forest, Ink and Candy. Switch on the hand-drawn style for a sketched look, or animate the connectors to show how a process flows.
MERMAID CODE, TOO
Write Mermaid code in the built-in editor with live preview. Get plain-language help when something is off, with the line marked. Open .mmd, text or Markdown files, and save the result as a PNG in your Gallery, as an SVG, or as a .mmd file.
EXPORT THAT LANDS WHERE YOU CAN FIND IT
Save PNG or JPG to your Gallery, transparent PNG for slides, PDF and SVG through the system save dialog, at 1x, 2x or 4x size. Share to WhatsApp, email, Drive or your documents.
PRIVATE AND OFFLINE
No sign-in. Your diagrams stay on your device, and drawing, Mermaid preview and export all work without a connection.
FREE TO START, ONE-TIME PRO
Drawing is free and shows ads. An optional one-time Pro upgrade removes ads and unlocks the extra libraries, themes and templates. There is no subscription.
GOOD FOR
• Students: algorithm flowcharts, assignments, revision notes
• Developers: ER diagrams, system flows, Mermaid charts
• Work: process maps, decision trees, approval steps
WHAT IT DOES NOT DO
No real-time collaboration and no cloud sync. It does not open files made in desktop diagram programs.
