How do I get my $1.99 back. **Developer response:** This app is all about statistics and we didn’t try to hide those features. We hope that you found them. If not please let us know calc@dogahe.com ### 1/5 — No manual = no good *2014-10-19* It is statistically impossible to be able to figure this app out without a manual. ### 1/5 — Simply Does not Work *2014-05-19* It's very simple: try using, e.g., nPr function. How do you use it? I assume this is permutations. But what key do you press first? 5 or the function key? How do you clear the register so you can enter a new problem? I would think by hitting "C" or "MC" or something logical like that. Oh, perhaps the problem is that I don't know how to use it? Where is the manual? Can't find it on the web site. And, IT CRASHES. **Developer response:** To find the permutation of 2 out of 5, you will press 5 nPr 2 = You clear the calculator by pressing AC. C will delete only the last number in the calculation. This is not an RPN calculator, so there is no concept of register. Please let us know how you were able to make the calculator crash? ### 1/5 — Crashes *2013-09-28* When I hit various button in the calculator it just crashes. For instance the number 0, which is pretty important to be able to use on a calculator. Don't buy! **Developer response:** We don't believe if you update to the most recent version, this app will crash. Please try and let us know. ### 4/5 — N-1 *2014-07-23* It's a fine buy, but for class, my instructor teaches the standard deviation with n-1 instead of just n. It would be helpful to have that feature. **Developer response:** Thanks for your feedback. Wouldn't what you are looking for be what we call sample standard deviation in this app which uses (n-1) as opposed to population standard deviation which uses n? ### 4/5 — Thanks, but. *2014-04-10* I like it, but could you put variations as well. **Developer response:** Thanks for your feedback. Could you please elaborate on what you mean by "variations"? ### 5/5 — Good deal *2023-10-17* This is an affordable way to get a great calculator! I have both the iOS and iPadOS versions. I like how he has adapted the calculator for iPad. ### 5/5 — Great *2020-01-31* Couldn’t be happier with a statistics calculator. Does all I need and more. ### 5/5 — The manual on the website is really clear! *2015-09-02* I started messing around with all of the different functions, and the manual on the developers website was a great way to do this. Not sure if some of the other commenters here made the effort to go online, so definitely take a look. The developers are pretty responsive with any issues too. ### 5/5 — So helpful *2014-01-17* Very helpful statistics calculator. Just plug in the numbers and all you need is right there and if you wanna get more advanced and see the regression models and do interpolation, a few button presses and swipes will do the trick. The results are also very accurate, never had seen any problems with this app. Thanks developers. ## Most praised reviews (5 highest-rated) ### 5/5 — not bad *2013-11-10, version 1.07* Needed a statistic app to compute z scores, standard deviations, and other parameters, and this did the job quite well. It automatically computes these parameters for any given set of scores, is easy to use, and has an attractive layout. ### 5/5 — Brilliant *2013-11-02* Absolutely a charm to do statistics calculations with this app. Hardcore calculations done very precisely, haven’t seen a single fault, yet very artistically and beautifully designed interface that flows from page to page. Just hit buy, you won’t regret it. ### 5/5 — Brilliant app *2013-03-21, version 1.0* Finally binned my 40 - year old Casio pocket calculator and moved into the 21st century with this app. Need to do basic stats (means, medians etc) on lists of data and this app is brilliant - intuitive, straightforward, stats appear automatically. Haven't yet done more sophisticated stuff but am sure will do equally well. Can't praise it highly enough. A bargain at £1.49. ### 5/5 — Great statistics calculator *2012-12-28* Very well designed and comprehensive! Great job! ### 5/5 — Simply brilliant *2012-12-12* For a while, I was looking for a calculator specialized in statistics to help me with design of experiments. I just found one which has all I needed. Besides the wonderful price, accurate functioning, implementing variety of regression analysis models and professional interface design adds more value to this simply brilliant app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
