Apple’s system apps like Notes, Reminders, Weather, Mail, and such are pretty basic ones considering the third-party options that are available on the App Store. However, these apps sometimes hide some nifty features that users do not even know about. The iOS Calculator app is one such app that looks pretty basic at first glance. However, did you know that there is a scientific mode hidden inside? Well, if you didn’t, now you do, and here’s how you can access it.
