HiEdu Scientific Calculator He-580

(Just what I was looking for). This Comprehensive and Easy to use Scientific calculator has MOST if Not all combinations that deal with basically anything related to, or involved with most types of calculations and problem solving. This Includes "ALL" types of equations or conversions, as well as working with chemistry and even More! The Bonus is that it's also"FREE with NO adds !"

Now, this is something weird.. there are multiple reiterations of the same calculator from the same developer: the 570, the 580, the 580 Pro, the "Pro", and the "All in one".. but nothing indicates *in what* these versions are really different, except that the Pro's have no ads. Oddly enough, the 570 seems to be the most downloaded and reviewed one, or maybe it makes sense because it's an older version? In any case, it keeps getting updated fairly often, just like the other three, or four..

It has better performance compared to the other scientific calculator apps I've tried. It does't lag even in my ancient Samsung Duos. And this app keeps its functions separated, which makes it even more effective. It does't hiding those options (like conversation options) behind buttons like a physical calculator. Great work!

BEST SCIENTIFIC CALCULATOR YET!!! I love the fact that it's easy to use and in my opinion it has the best interface I have seen! Hope to see more features in the future. I LOVE it!

Fantastic calculator. Would have given it 5 stars if there was a financial sector. After the latest update the currency converter no longer works. Get error "please check your connection and try again". This is the best calculator app please fix this. Thank you

Seems excellent scientific calculator and much more to explore. I wish the team must Keep upgrading this calculator with advance Maths, physics, electrical and electronics formulas. And off course the Chemistry periodic table with searching fields.

It's very helpful and very easy to access. One thing I also like about it is, the app able to link you to other related courses like chemistry and physics though it's a calculator. It's fun using HiEdu scientific calculator He-580

Best app ever. My humble suggestion that it would be more better if there is 'Check back' 'Check forward' and 'Correct' button in standard calculator mode instead of undo pie and ^ button. Thank you.

It's really good. But the touch sounds are a bit annoying. Why don't you make tge touch click spund like the real ones? That's it nothing much to complain about. Good job. It still needs furtger polishing. Because your app has rwached a stage where these small thibgs matter.

Excellent app with all the right features and settings, all for free. I totally recommend it.

the app is quietly smart and accurate .it is offline,contains all the themes,with all functions but easier to use.appreciation to a developer of this app.I advise everyone who needs real mathematical programs to use this app you will never regret!!!!

It is a great app and lives up to its promises. It has great mathematical features as well as science. It also has graphs , converting , chemistry and many more . I love it

This calculator is very good. Makes things easier for me than the previous ones I was using. The features are really helpful and stress free.

Best calculator I have ever used. I am fond of my physical touch calcs (TI, Casio, etc.) but this is superior in function in everyway. Thank you for such thoughtfulness in design.

Awesome all i need as a scientist in one app, i describe this as (great accuracy), continue with the good work.

Very nice app. A few of the conversion tables are a bit too limited, but still useful.

It works great, the only problem are the ads at the top of the calculator, which isnt that much of a big deal.

Easy to use with a lot of other function besides the basic and scientific calculator. 👍🏼👍🏼👍🏼

I stumbled across this app looking for a single app that packs in a lot I am not disappointed thank you developer, excellent job done, I would highly recommend this app to my friends and coworkers, keep up the excellent work.

Great app. Perfect substitute for my potato calculator and as my new one haven't been delivered yet. Easy to use and effective. 5 star app indeed during this terrible pandemic.

There's a good one it help on to calculating things easy and hence learning of students. I will even like to rate you stars.

good, works as expected. documentation requires some effort to understand. It will be useful if a series of calculations can be saved as one set, with subsequent calculations using the result of one or more prev calculations.

It's awesome to me. Simple in all it's calculations. It covers all the basics as a student taking sciences. Happy for it.

This is a super calculator. I have been looking for this kind of calculator for a long time and now I got it. It covers many areas of mathematics and science, it's a great app. Many thanks to the developers

This app is very awesome,user friendly, accurate and more of other attributes if you haven't downloaded it please do so since you're missing smooth things,I am a engineer and I am benefiting from this✨✨💯💯.Thank you

I havn't used it yet. I used some scientific calculators, but whenever I saw advertisement in calculator display, I suddenly uninstalled that and gave review of 1 star. Hope this calculator will not let me down.

Very useful, clear and explanatory application. I really appreciate the team for developing this app which removes the fear of Mathematics in the minds of people.

Awesome application. Added much more features than any other calculator! Most beneficial side is it's free. Thanks a lot.

This app is useful and important for me. It is easy to use. Math functions are complete so I highly recommend it. Excellent app. Thank you very much.
