Octopus Calculator app for iPhone and iPad

As a middle-aged programmer who recently lost his job, I developed OctoCalc while learning Swift. What started as a simple learning project unexpectedly gained traction after its release on the App Store, with users even willing to pay for it. Touched by this trust, I made a firm commitment: to create a calculator truly worthy of users expectations.

I dedicated countless hours to studying the limitations of existing calculators and carefully listening to every users feedback. After two complete rebuilds and numerous sleepless nights, Im proud to present version 3.0.

Today, OctoCalc is an intelligent calculator with a human touch. It not only reads out buttons and calculation results but also provides different haptic feedback to make calculations more tactile and engaging. To make the calculator more accessible, I even invited a visually impaired user to test it and incorporated their needs into the design.

You can simply speak out your calculations, and OctoCalc will instantly compute them for you. Its also quickly accessible from the Control Center. Every feature added stems from my pursuit of making calculations simpler and more intuitive.

Starting over in my career hasnt been easy, but every word of encouragement and support from users warms my heart and strengthens my determination to keep improving. Im currently working on even more thoughtful features. In the next major update, I believe youll be amazed to discover just how much a simple calculator can enhance your daily life.

Thank you to every user for your support and trust - your appreciation is my greatest motivation. Lets look forward to discovering more possibilities with OctoCalc together!
