About this app
ModForge turns your phone into a portable math sketchpad. Plot functions, construct 2D geometry and build 3D surfaces on a smooth canvas that works with touch or a stylus.
BUILT FOR MATH AND ENGINEERING
• Function board: plot expressions, inspect curves, differentiate and integrate
• 2D geometry board: points, lines, circles, polygons and freehand construction
• 3D board: rotate and inspect spatial surfaces from any angle
TYPE IT, DON'T DRAW IT
Describe what you want in plain language and ModForge places the figure on the canvas for you. AI credits refresh every month, so you can experiment without starting from scratch.
SAVE AND CONTINUE ANYWHERE
Sign in to sync your boards to the cloud. Open the same canvas on another device and keep working exactly where you stopped. Every board keeps a preview thumbnail so you can find it at a glance.
DESIGNED FOR SMALL SCREENS
• Gesture-friendly controls and a compact toolbar
• Light and dark themes
• English and Simplified Chinese interface, including the board menus
• Board content follows your language setting
MEMBERSHIP IS OPTIONAL
Free accounts can keep up to 4 boards in each category and use the 2D board offline without signing in. Membership removes the storage limit and adds a larger monthly AI credit allowance.
ABOUT US
ModForge is an independent project for students, teachers and engineers who want to see math instead of only reading it. We read every message sent to our support address.
