Math Collector Support
Solve addition, subtraction, multiplication, and division — and fill your collection with stars.
Math Collector is a number-play app for practicing the four basic operations through short missions and 60-second lightning challenges. The stars you earn unlock new friends in your collection, one by one.
Features
- Four operations: Choose addition, subtraction, multiplication (times tables), or division, level by level.
- Rocket Mission: Solve 8 problems within the time limit to earn stars. Retry any missed problems right away.
- Lightning Challenge: Answer as many as you can in 60 seconds and beat your best score.
- Collection: Every few stars unlocks a new friend in the Stars, Plants, or Fish theme — 20 per theme.
- Growing buddy: Your buddy grows from an egg to a puppy as you collect stars.
- Grown-up settings: Settings are behind a simple math check. View progress and change music and theme there.
Minimal personal data
- No sign-up or login.
- Stars, records, collection, and settings are stored only on your device, not on our servers.
- We never ask for a name, age, or contact details.
- Ads are non-personalized only, and the app never asks for tracking permission (ATT). No ads appear while solving problems.
FAQ
- How do I open Settings? Tap the gear at the top right of the home screen, then solve the grown-up check.
- Where do ads appear? Only as a small banner at the bottom of the home and collection screens — never during missions or challenges.
- The app only works in landscape. It uses landscape to show problems and cards large. If rotation lock is on, turn it off in Control Center.
- How do I turn off sound? Background music can be turned off in Settings. Sound effects follow your device's silent mode and volume.
- Will my progress move to a new device? Not automatically, since there's no account or server storage. Restoring from an iCloud device backup may restore app data too.
- How do I delete all my data? Deleting the app removes everything stored on your device.
