All-in-1-Calc Free

Great app, but the currency conversion is way off. As of today, 1€=$1.20, but even tough the app shows it downloaded today's currency conversion rates, 1€ comes out to $1.06, which is absolutely incorrect.

Installed then checked update. FIVE years ago? Faults reported by users but nothing done about them.

I have been using thid app for years on my tab I did not find better calculater yet and its free thanks guys.

This is a great tool with a simple interface and lots of features.

I use this app for last 3yrs and its very good and has all the conversations. This app is helpful.

Functional, elegant, and FREE

This is very much necessary for maths. I really appreciate.....

I been using this calculator for years. It's the best out there.

Really all in one...

This is by far my favorite calculator ever! Always use it!

Very nice. It takes me back to my student years...

I really like the format and typically use this calculator, notified of bug Jun 4 but still no fix. Back to ti-86

wow nice app its amazing thanks

The best mix of scientific and ordinary calculator I've tried. I use it for several years and don't want to change for another one.

Used to be the best calculator around. Hasn't worked on Galaxy S3 with Android v4.4.2 for about a year (2014). It no longer resizes to full screen so the number buttons are all smooshed together now.

I recently got a New Huawei Ascend Mate 2 (MT2L03) w/Android v4.3. This app works on all my other phones and tablets except this Huawei. The app display is shrunk to half the size that it is totally unusable. Anyone else has this problem?

I really enjoy this program. Has worked perfect in every situation I've needed it.

If you are a science student,then go for this one.

Modulo doesn't work on HTC Inspire 4G. Everything else is nice

It give every function

Please keep going!

My husband and I recently were stationed in Germany. This calculator converts everything! Miles to kilometers, Fahrenheit to celcius, grams to ounces, you name it, this app does it. Fairly up to date exchange rates, too. I highly recommend this app!

Was Searching for one of these..

I like, Enough said.

Simply the Best.....calculator of all time

It's a good application to delhi i calculation number

We should be able to calculate like this. 200 X 5 % + equals, and get the result 210 (200 plus 5% thereof). This app doesnot do this simple sum.

best calc available in play store

All the tools required in one app. This is really great.

not fit on screen

This app is great. It does the job of several apps.

Very Very Good This Apps , I am very happy now .But little bit problem about icon, this icon is not nice

Previsouly I need a scientific calculator, an unit convertor and a currency converter. Now I can replace 3 tools with this one. With regard to functionality, it worths 5 stars! I deduct 1 star because of the its ugly face + small font in big button + the "=" in an unsual position.

I have concerns this app will become obsolete as the new Android builds come. Would like to buy the paid version but the price is too high IMO for an app that may soon not work anymore.

Like many other of its kind, when one tries to calculate the cubic root of a negative number (example: (-8)^(1/3)), it gives an error message. Could you fix it? Also, it's a pity it isn't multi-window compatible.

Works like a charm. I am a device tester and I switch phones every 3 months. I've never had problems when using it on any brand or with any model. I always recommend it to my students. Kudos for the programmers and designers :D

I love apps that do more than one thing and this does it all, even currancy. (tips calc would be perfect)

Use it everyday, as i really need the thousand separator. Interface clean and useable. One little problem, on HTC Flyer, it don't go full screen.

Though not listed, but this app do have permission to phone ID/IMEI ect . There is no reason why it should. Otherwise a good app, really all-in-1. Added comment: it seems any app targeting Android 1.5 or below will be granted this permission BY DEFAULT by google. As said before otherwise a good app.
