And the history feature makes this app a very unique one with great usability. ### 5/5 — Great calculator *2012-04-05, version 1.25* Great and very useful calculator specially for engineerings ### 5/5 — Great history feature *2012-03-29* The expression and history feature are great and big time savers. With this price they are practically giving this out for free. ### 5/5 — Fantastic calculator *2012-03-13, version 1.24* This scientific calculator is fantastic. It reminds me of my old Casio calculator that I loved in high school. I recommend it 100 percent... ### 5/5 — Ingenious construction *2012-02-16* This app is cleverly created to save effort and time, the functionality and ease of use make this the only app I use for calculations. Should be priced much higher, Thanks Developer!! 👏 ### 5/5 — Excellent especially in complex calculation *2012-02-07* I have $99 texas instrument calculator. But this app has the exactly the same function with that heavy TI calculator. It's just great one with only $0.99. ### 5/5 — Very useful application for iPhone *2012-01-25* I have been always looking for such a user friendly scientific calculator for my iPhone ### 5/5 — Good tool *2012-01-24, version 1.2* Nice interface ### 5/5 — Advanced Scientific Calculator *2012-01-14* This calculator is great. I love the features. In particular the sliding function - which brings up more functions. Also love the dice feature - now I can play Settlers of Catan on the go :). ### 5/5 — Cool calc *2012-01-12* I like the button configuration and the sliding window which enables a user friendly view and a great deal of functionality. Hope there will be more buttons coming on. In the short term though, having more memory (assigned to variables like a, b,c..) would be nice. That will help a lot when I perform calculations with a few variables. ### 5/5 — Very user friendly *2011-12-27* Just the most user friendly calculator app I have ever tried. Just take a look at how the quadratic or system of equations is handled in this app. Simply genius! Kudos to these guys! ### 5/5 — Very useful tool *2011-12-19* I have been using this calculator for a week, and I was able to do almost every thing that I need for my projects and in daily life. It is very user friendly and fast to use. ### 5/5 — Incredible *2011-12-01, version 1.2* Easy to use and beautiful interface. ### 5/5 — Great calculator *2011-11-17, version 1.1* A must have for any engineer, scientist or accountant. Very useful. ### 5/5 — Love it! *2011-11-15, version 1.1* I love the quadratic equation solver. Use it all the time. The polar and rectangular conversion is great for phasor computation that I need for my circuit courses. Great app with great price. ### 5/5 — Best calculator *2011-11-14* I've tried a few. They are often overpriced and crash too often. This offers every feature imaginable and is priced perfect. Well done!!! ### 5/5 — Highly recommended *2011-11-10* Great calculator! Better than the one that comes with the phone. I tried it and I thought it is very helpful. Highly recommended! ## Most critical reviews (10 lowest-rated) ### 1/5 — Scientific not working *2024-08-29* Scientific not working **Developer response:** Please let us know what functionality you are looking for and we will walk you through the steps. You can email us at calc@dogahe.com. All the functionality that you see in the app description should be working. So we are surprised by your message. We hope we can help you find what you are looking for. ### 1/5 — Ripoff *2019-04-12* This is NOT GOOD for a 4 year old. Trying to use the calculator will confuse any user so much they will forget what they were trying to do. Shame on you. **Developer response:** The age rating of the apps are not assigned by the developers. The developers answer a series of questions and Apple determines the age rating. The age rating of this calculator is determined to be 4+ which is exactly the same as the age rating of Apple’s calculator app and many other utility apps. I understand you feel this calculator is not appropriate for a 4 year old but personally I do not give an iPhone to my 4 years old to be even worried about which apps he or she is using. I don’t think I ever touched a smart phone or a calculator before I was 9 or 10 years old. ### 2/5 — Very confusing *2023-04-18* I am use to using Casio and TI. Entering the data and getting results is very confusing. Casio especially is much easier. I will stick that. Glad I only paid $6 for this bundle. **Developer response:** Thanks for your feedback. We tried to be consistent with many mainstream calculators as far as the order of button presses. We believe most of the order of operations are pretty straightforward and logical. Please let us know which operations are confusing to you? ### 3/5 — Awesome scientific calculator!! *2011-10-30, version 1.1* Great scientific calculator app. Highly recommended!! ### 5/5 — It may not be pretty *2018-04-19* But brains are better! This is a hidden gem that deserves a closer look. So many scientific calculator apps get it almost right but fail miserably where it counts. This one nails it. ### 5/5 — Awesome App! *2018-01-08* Great functionality! Fraction calculations, degrees minutes seconds conversion and equation solvers, couldn't find these in a single app elsewhere. And now a right triangle calculator with some cool graphics, great work. ### 5/5 — Great calculator *2013-01-12* The conversion from degrees minutes seconds to decimal comes very handy among other features like fractions and quadratic equations, all of them very unique to this all around calculator. The colors are very vibrant too. ### 5/5 — Best for me *2012-11-13, version 1.27* Innovative ideas Specially for transformation in minutes degrees and seconds. Also good in probability applications Simple and useful ### 5/5 — Excellent *2012-08-18, version 1.26* Best calculator offered in the app store.. Great buy at 1 dollar ### 5/5 — Awsome!!! *2012-08-09, version 1.26* I used it in my exams and i got A! Thanks to Dr Dogahe! ## Most praised reviews (4 highest-rated) ### 5/5 — Best buy *2012-07-08, version 1.26* Amazing, all college, even high school students should have this app! ### 5/5 — Psychologist *2012-06-19, version 1.26* Just started using this app. Easy research calculations. Simple and Simply marvelous. ### 5/5 — Awesome! *2012-05-25* I wish I had this in high school! Solves quadratic formulas for you :) The amount of time that has been put into getting the features and functions to work smoothly, and intuitively, shows. ### 5/5 — Solid calculator *2012-04-23, version 1.25* Saves me a lot of time checking my kids homework. They are in the middle school and high school. This is solid. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
