Math you can walk around.
GanitAR drops 3D math objects onto your desk. Count them, add them, rearrange them, and explore geometry from every angle — right through your iPhone or iPad.
Free on iOS & iPadOS
Why GanitAR
Drop math into your space
Place 3D shapes, prisms, and spheres on any flat surface. Walk around them, kneel beside them, see them from every angle.
Tap two piles to combine them
Addition and subtraction with movable shapes. Tap one pile to send it flying into the other and watch a + b become the sum. Place-value blocks kick in for hundreds, tens, and units.
Scan or speak a problem
Point the camera at a printed math problem, or say it out loud — both the OCR and the speech recognition stay on device.
On-device, no accounts
Nothing is uploaded. No sign-up, no tracking, no ads. Camera and microphone are used only on-device, never recorded.

Who it's for
For Students
Stop staring at numbers on a page. GanitAR turns your room into a math lab. Watch shapes appear on your desk, walk around a sphere, count cubes from every side. Spatial intuition is the shortcut.
- •Counting and grouping in 3D
- •Tap-to-combine piles for addition
- •Subtraction in color — blue cubes stay, red cubes leave
- •Place-value blocks for hundreds, tens, and units
- •Scan a printed problem or say it out loud
- •Print a practice worksheet from your phone
- •Geometry you can orbit
- •No login, no streaks, no pressure
- •Self-paced — never timed
For Teachers
An AR demo loop that runs on the iPad you already have. Use GanitAR as a five-minute classroom warm-up, a station activity, or a demonstration on the projector. No accounts to manage, no data to protect.
- •No student accounts to provision
- •No data collected — FERPA-friendly by default
- •Works on any ARKit-capable iPad
- •Free, no licensing paperwork
- •Air Play to share to a classroom screen
What's inside
Two modes. Pick the one that matches the moment.
Four guided practice games
Hand the iPad over and let the app pick the problem. Four games, each focused on one habit of mind.
- •Count the shapes — read off how many appear on the desk
- •Add two piles together — tap-to-combine, see the sum
- •Level pack (3 levels) — progressively harder mixes
- •Count the boxes — quick visual subitizing
Bring your own problem
Three paths in, one shared AR scene out. Every step runs on-device.
- •Scan a printed problem — Apple DataScanner (iPhone XS+)
- •Say it out loud — "twenty plus seven" parses to 20 + 7
- •Generate a practice worksheet PDF — AirPrint or share
- •Auto place-value when any number is over 20
- •Three retries on a misread, then it suggests printing a sheet
Geometry that lives in your room
GanitAR is built on Apple's ARKit and RealityKit. Shapes anchor to real surfaces, hold their place as you move, and respond to your taps. When you can move around an idea, you understand it. The app icon adapts to iOS Light, Dark, and Tinted appearance so the home screen always looks right.
Don't have an iPhone handy?
Try GanitAR in your browser. Six hands-on demos — tap-to-combine piles, place-value blocks, the expression parser, voice input, and the printable worksheet. AR shapes stay on iOS but the math feel ports.
