## NumJam Description
NumJam: The Musical Calculator turns everyday calculation into something you can play.

Use a classic calculator while every tap triggers a musical note. Build equations, tap rhythms, switch between free sounds, and turn numbers into small musical ideas. NumJam is made for quick math, playful sound, and anyone who wants a calculator that feels more alive than a normal keypad.

Free Features:

• Classic calculator for everyday math
• Multiple calculators on iPad - Up to 2 classic calculators
• Musical notes mapped to calculator buttons
• Free instrument sounds
• Mute sound anytime from the header
• Clean layouts for iPhone and iPad
• Fast tapping for musical play

• Scientific calculator
• Multiple calculators on iPad - Up to 4 calculators
• Full instrument library
• Recording tools for calculator performances
• Save and replay your MiniPlay recordings
• Pro layouts and sound options
• More ways to build rhythms, patterns, and musical calculator ideas

NumJam works as both a calculator and a playable sound pad. Use it for simple math, experiments, patterns, rhythms, or just turning numbers into music.
