It perfectly combines the simplicity and ease of use of the built-in calculator with more advanced operations available on other scientific calculator apps. The UI is simple and clean, whereas others feel a lot more like handheld scientific calculators emulated on the iPhone, with really busy UIs full of myriad tiny buttons.",

Stay tuned for NSC2 which will release on web and desktop (Windows, Mac, Linux), in addition to the current iOS and Android platforms. NSC2 will feature a revamped user interface and a more comprehensive set of maths functions. Expect to see the launch by April 2023. Send your suggestions for the new NSC to www.stultusstudios.com/nsc-feedback and stay up to date with our progress at www.stultusstudios.com/notice-board In the mean time, we've also updated NSC to 1.2.0 on iOS, which comes with many fixes and improvements. • Optimised the app for larger screens on more modern iPhones (letterboxing is now a thing of the past) • Removed ads completely (for everyone) • Improved performance • Added a notice board to keep you up to date with recent changes and future updates (check Settings) • Removed referral system (contact us if you've referred people and need a premium NSC Plus code) • Fixed various crashes • Updated the \"Send Feedback\" and \"Help with translation\" pages, to redirect to a web form."
