pCalc – the calculator business plan

I installed yesterday pCalc on my iPad and was quite amazed by the way the developer invented a really innovative business model of freemium … for a simple calculator.

As any freemium model, the basic calculator is free and high-quality and the developer identified a few typologies of users that need special functions such as HEX/Binary handling, RPN with multi-lines… and all those features can be purchased in-app in a super smooth way.

It’s jus brilliant to see that something as simple as a calculator can be a field of innovation like this.
