OUR STORY
HaPi started with something I have always loved: numbers.
I use a calculator all the time, and I have always enjoyed playing with numbers and finding little reasons to make math more fun.
One day, I thought: what if a calculator could make people smile too?
So I started playing with the idea. A few experiments turned into funny sounds, unexpected reactions, and eventually HaPi.
What started as a simple idea to make math a little more fun became something much more entertaining than I expected.
Sometimes, even a calculator can have a personality.
HOW IT WORKS
Pick a theme and start calculating. Every number key shows its own picture, displays its name in your language and plays its own sound.
WHAT YOU CAN DO
• Add, subtract, multiply, divide and work with percentages
• Hear a different sound on every key
• See a picture and a name on every number
• Watch confetti burst when you press equals
• See your full calculation above the result
• Switch themes with one tap
• Turn sounds on or off at any time
• Use HaPi in your own language
GREAT FOR
Quick daily math, checking a bill, or a little fun with sounds.
