Master Math — Support

Help, answers, and how to reach us.

Master Math is a friendly multiplication, division, addition, and subtraction trainer for kids, set up and managed by a parent or guardian. If something isn't working or you have a question, this page should help — and you can always email us directly.

Getting started

• No account needed. You can use Master Math right away on a single device — just add a player and start practicing. Everything stays on your device.
• Pick an age mode per player. "Young Kid" focuses on addition and subtraction with counting pictures and a number line; "Big Kid" does multiplication and division.
• Practice, Test, and Flash Cards. Practice adapts to what your child finds tricky, Tests give a scored challenge, and Flash Cards let them think first, then reveal the answer.

Players and PINs

• Add or remove players from the player-selection screen (up to 30).
• Kid PIN. You can protect a player so a 4-digit PIN is needed to select that card.
• Parent PIN. On a family account, a parent PIN protects the Parents dashboard and any changes that would remove progress.
• Forgot a PIN? On a family account, sign in on any device to reach the Parents dashboard and reset it. In single-device mode, email us and we'll walk you through it.

Family accounts & syncing across devices

• A free, optional family account lets progress sync across devices.
• Sign in with the same email on each device and your players and progress appear everywhere.
• Progress is saved even when you're offline and syncs automatically the next time you're online.

Managing your data

• Delete a player (and its progress) any time from inside the app.
• Delete your whole account by emailing us at the address above — we'll remove it.
• See our Privacy Policy for exactly what we store and why.

Troubleshooting

• Progress didn't sync? Make sure you're signed in with the same email on both devices and connected to the internet, then reopen the app.
• App looks stuck? Fully close and reopen it. If it persists, email us with your device and app version.
• Wrong language? Tap the flag in the top bar to switch between English, Hebrew, Spanish, Portuguese, and French.
