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 and plays its own sound. WHAT YOU CAN DO β’ Add, subtract, multiply, divide and work with percentages β’ Hear a different sound on every key β’ See a picture and a name on every number β’ Watch confetti burst when you press equals β’ See your full calculation above the result β’ Switch themes with one tap β’ Turn sounds on or off at any time β’ Use Hapi in many languages GREAT FOR Quick daily math, checking a bill, or a little fun with sounds. FREE VERSION β’ Music and Animals themes β’ The full calculator with sounds and confetti β’ No ads of any kind PREMIUM β’ Extra Premium themes β’ New themes added from time to time Themes are updated from time to time. Some themes stay for a while and then make room for new ones. You can choose a monthly subscription, a yearly subscription or a one-time Lifetime purchase. The yearly subscription starts with a 14-day free trial. After the trial, it renews automatically at the yearly price unless you cancel at least 24 hours before the trial ends. You can manage or cancel it in your App Store account settings. This is always your choice. MADE BY AN INDEPENDENT DEVELOPER Hapi is made with care by an independent developer in Δ°zmir, Turkey.

Verdict
The clearest difference is in-app purchases: FRAQ CALC Lite at none against Hapi's 3. FRAQ CALC Lite also leads on update cadence (daily vs every 2 weeks). Hapi's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
