Why would you NOT spend money on a calculator app if it’s better, or you just fancy it? An iPad pro costs 1000 bucks and your time is probably worth around 100 bucks an hour, so if an app is good and costs less than 25 bucks you shouldn’t even stop to think before buying it. A person with a well paid job that thinks twice about paying 5 bucks for anything he could potentially use for work even once is doing it wrong.
