Open Settings → Snapping. Make sure Angle Snap is on. Use Snap Step to choose the degrees between snap points, and Magnet Strength to control how strongly rotation sticks to each step.
Open Settings → Visibility. Toggle Center Hub off to hide the crosshair marker, and Center Pin off to hide the dot at the exact center.
Open Settings → Visibility. Toggle Angle Labels on or off. This controls all on-canvas degree labels, including the crossing-angle labels shown where two lines meet.
Open Settings → Snapping. Toggle Grid Snap on to lock points to grid intersections. Adjust Grid Size for spacing and Grid Magnet for how close you need to be before snapping kicks in.
Open Settings → Canvas. Toggle Orbit Mode on to rotate the entire canvas around the center. Use Orbit Opacity to control the transparency of the overlay.
Open Settings → Canvas. Toggle Infinite Board on, then drag on empty space to pan and scroll to zoom. Tap Reset View to snap back to center.
Open Settings → Layout & Theme. Choose an app layout (Classic, Split, or One-Hand) and tap a theme in the grid below.
Open Settings → Developer. Toggle Low Power Mode on to lower visual quality for better performance. You can also pick Low Power from the one-time mode prompt shown on your first visit.
Open Settings → Canvas. Drag the Protractors slider between 4 and 12 to control how many protractor guides appear on the canvas.
Open Settings → Canvas. Drag the Text Scale slider above 1.0x to enlarge all on-canvas labels, or below 1.0x to shrink them.
The Point tool places pins at your fingertip. In Settings → Snapping, enable Grid Snap to lock points onto the grid. Adjust Grid Size and Grid Magnet to control spacing and snap range.
Use the Drag tool to nudge points. Long-press a point to show angle/length info. Drag from near a point to an empty spot to pan.
Tap a point to drag it. Drag from an empty area to pan the view. Long-press a point to see its coordinates and attached info.
Tap the first point, then the second. A line appears and live angle/length labels show automatically. Tap an angle label to enter the solver.
Tap the canvas to drop a point. Enable Grid in settings to snap points to the invisible lattice.
Drag around points to select them. Drag inside the loop to move everything together. Tap outside to redraw. Drag the bottom-right handle to resize.
Tap two points. The line locks to the nearest axis. Great for horizontal, vertical, or 45-degree construction lines.
Tap the first point, then the vertex point, then the end point. A right-angle symbol and 90 degree label appear instantly.
Tap to set the center, then drag outward. The radius length is shown live. Points can stick to a circle at any angle.
Tap two existing points. A new point appears at their exact center, linked automatically.
Select a point, then select a line. A perpendicular segment is drawn from the point to the line.
Pick two lines to get their crossing point, or two circles to see where they meet up to two intersection points.
Tap an existing point (or tap empty space to create one), then tap a circle. Two tangent lines are drawn from the point to the circle, with the tangent points bound to the circle edge. The radius-to-tangent angle is always 90 degrees.
Tap 2–4 existing points. A new point is placed at their average position (centroid). Move any of the source points and the centroid updates in real time.
Whenever you connect points or make a shape, angles and distances update in real time.
Tap an angle text on screen. Use + / - buttons to set the desired angle. The vertex rotates automatically while keeping side lengths intact.
Open the Presets panel from the toolbar. Choose a theorem — Semicircle, Cyclic Quadrilateral, Tangent–Radius, Two Tangents, and more. Each preset loads a complete construction you can drag and explore to see the theorem in action.
After building a construction, tap Save in the Presets panel to store it. Your saved presets appear alongside the built-in ones. Tap any preset to load it instantly.
Tap the people icon in the top-right header. A teacher can Create Class to get a room code. Students enter that code to Join. Everyone's board syncs in real time — edits, moves, and cursors are visible to all participants.
Open Settings → find Snapping. Toggle Grid Snap to lock points to the grid. Use Grid Size to set spacing, and Grid Magnet to set how close you need to be for snapping.
Open Settings → find Visibility. Toggle Center Pin to hide the center pin, Ring Pins for orbit pivots, and Angle Labels to show/hide measurements.
In Settings → Canvas: enable Orbit Mode to rotate the canvas, enable Infinite Board to pan freely, and tap Reset View to snap back to center.
