### 5/5 — Excellent Calculator App

*2026-06-01*

I’ve been using the pro version for years, on both Android and iOS. As an engineer I find it’s the perfect blend of functions for most technical users without being overloaded with niche functionality. If the built in calculator app isn’t cutting it for you, try HiPer calculator.

### 5/5 — Super calculator

*2026-04-30*

Very good calculator. I am using it for last 5 years. It is user friendly and has a number of features for solving easy to complex calculations. I had purchased it for Android phone but recently I switched to iPhone but unfortunately I am not allowed to use that purchase.

### 5/5 — Customization!

*2026-04-08*

With the custom functions options this has become my goto calculator for non trivial calculations. Would love the option to expand on that by allowing custom infix operations!

### 5/5 — Excellent

Everything I need for anytime with maths.

### 5/5 — From a calculator geek

*2026-02-20, version 11.2.4*

This calculator is just totally awesome. I have been a geek about calculators since I got my very first Mickey Mouse Calculator back in 1972 when I was seven years old.  I’ve tried them all every Texas instrument version every RPN HP version, every cashier version you name it. But this one I love because it has a great expression screen to help is easy to navigate. You don’t have large books to read through. They’ve done a fantasy job with this calculator.  I paid for the premium version and I couldn’t be happier.

### 5/5 — 100% recomendaciones

### 5/5 — Still the best

*2025-11-30*

I’ve tried tens of calculators on both the Google App Store and the Apple App Store. This calculator remains the best. I’ve been using it for many years now, and strayed from it to use a few others, but I keep coming back to this one.

### 5/5 — Feeling

*2025-11-25, version 11.2.1*

While the app icon is ugly, the app itself is so good that I forget my phone is not a calculator
