Genius Calculator & widgets

Great calculator app. I hate switching from calculator app to convert app when I'm working. If you could add a molecular weight database, Every chemist in the world would be using it.

Really has everything you need and don't need all in one nicely designed app. Nothing gets in your way while using what you get familiar with and other functions I'm not too sure what I'll be using em for!? My phone is much smarter with this one....Tanx

Use it all the time, like the unit converter. Would be handy if it would remember/default to the most commonly used conversions.

I'm sure that I have everything I need and everything is easy to find. Any "improvements" cannot make it better.

This is the best I've tried. Love the history tab, easy to read, simple to use... great GUI.. Thanks a million!!!

Downloaded it for the widget, has a few handy functions.

Good app. Simple to use and fully functional. Highly recommended.

Storing my favorite conversions is so handy!

Small size, rich functions

its very usefull calculator

The unit converter is top notch, it also does 1 + 1 very well ;)

Exactly what I was looking for. A complete application for high level calcul and conversion

Good except for couple things: 1) it keeps buggin you to give your review. .5 star nick there 2) for conversions, forget Invert, just have "convert -->" and <--convert" 3) does not always clear previous entry when you start next entry with a decimal point 4) missing area conversions for ping and tatami

Best calculator widget I could find.

Big glaring missing item on scientific calculator is ability to enter a power of 10 for very large or very small number

Use it all the time at the petrol station I work at.

If you work in two different units of measure in one project then this is an indispensable app Plus it's a great calculator to boot

many functions easy to use. One little thing, please sort the conversions to make them easier to find. This is my goto calculator always.

This is what am looking for!

Don't use this app

Use it a fair bit for work

Great app, I just wish the 'from' and 'to' in each category on the conversion screen were in alphabetical order

The best I have tried after looking at numerous similar.

Excellent tool

Excellent

I love this calculator especially the conversion feature.

Great

Lock screen widget is not working on new phone Lenovo K3 Note K50a40 lollipop 5.0 (worked on 4.2 JB). Another App "Bashfull clock" is though working on the new phone too.

5 stars for the lockscreen widget

Widget works great

Excelant

The widget is finally staying in place, but when typing into the calculator the reaction time is so slow. Widget is useless at this point since going into the app would be faster as long as it takes for widget to show results. Will be looking for a new calculator widget.

I can't apply the widget, it doesn't seem to exist. A good reliable calculator with no ads. Would be a bonus if the widget would work and if I could sort by long pressing keys.

Great app and NONE of the bogus permissions like most others.

Very useful,works like is supposed to be,I really like this app

Great App. Use it all the time

Has gotten me out of trouble

The best app ever

Does fine. :)

Great app for a lot of things!!
