What is free, and what does Pro add?
VizMath is free to download and use. Pro is for production exports: 4K / 60 fps video, longer video and GIF without the mark, extra-high-resolution images, AR video, Print Fix Studio, 12-scene stories, and Story video and handouts.
I paid but Pro is not unlocked.
Open Settings → Subscription → Restore Purchases. Purchases are tied to your Apple Account, so use the same one you bought with; one purchase unlocks iPhone, iPad and Mac. If it still does not appear, write to us with the date of purchase.
How do I cancel a subscription?
Settings → Subscription → Manage Subscription in the app, or in your Apple Account settings. Cancel at least 24 hours before the period renews. Lifetime is a single payment and never renews.
How do I get the best out of the Problem Solver?
Type a problem as you would write it: 2x + 3 = 7, x^2 − 5x + 6 = 0, a system separated by commas, d/dx x^3 sin(x), integral of x^2 from 0 to 3. To scan, hold the page flat in good light with one problem in the frame, and check the recognised text before solving; correct any symbol that was misread. Letters such as a, b or k become sliders, so you can change the numbers and see the new answer at once.
How do I build a construction?
Open the Tools tab, pick a tool and tap points on the canvas, or type commands such as A = (1, 2), Segment(A, B), Circle(A, 3), Intersect(c1, c2) or Pyramid(A, B, C, D). Drag any free point and everything built from it follows.
What does the Apple Watch app do?
Dictate a problem or write it with Scribble and get the answer, look at graphs and rotating 3D surfaces, and turn the Digital Crown to change a slider.
I think VizMath got the math wrong.
Send us the equation and a screenshot. Wrong math is the bug we fix first; we aim to fix it within 72 hours. Explanations are checked by the math engine, but for anything that matters, check the result yourself.
Does it work offline?
Yes. Graphing, 3D, constructions, the solver and the on-device AI all work without a connection. Only buying or restoring Pro needs the network.
Which languages?
English, Español and Tiếng Việt.
Where is AR, and which devices have it?
AR is on iPhone and iPad. Open a 3D surface or solid in AR to place it in the room at its real size. The camera is used only while AR is open.
How do I 3D-print a surface?
Run the print check on a 3D object first; it tells you what needs fixing before the model can be printed. Then export it as STL, OBJ or USDZ and open the file in your printer’s slicer.
