Calculator Plus is a standard and scientific calculator that has simplicity at its core, while not compromising on functionality. Even with its simple user interface inspired by the built-in Calculator app on iOS, it offers much, much more - and with no ads! With full expression and live answer preview, be faster than ever at calculating, and see exactly what you typed. Understand your answers by displaying them in exact form, scientific notation, fractions and more.

Verdict
The clearest difference is ads: Calculator Plus v2 at none against Calculator's shown. Calculator Plus v2 also leads on update cadence (every 2 months vs every 13 months) and monetization model (free vs ad-supported). Calculator's advantage is ratings volume (910 vs 133). On price, rating and in-app purchases there is nothing between them.
