handyCalc was born in a cold winter in Shanghai. In that days, there is a big snow fall off in this city.
handyCalc means calculate in your hand. It’s designed as it said: “Solve things in your hand.”
I decided to design this calculator since I saw that google android challenge. At that time, i’m still a college student studying civil engineering in Shanghai.
When the first release of handyCalc 0.1 was finished, it takes about 35000 lines of java code which is written in about 4 months. it almost drive me mad to do so much works.
handyCalc was finally failed in google’s ADC in 2008.
Life is always like this. two months after ADC, i left the college and started a new life, working in a company in daytime, and write code at night.
handyCalc does not change much since version 0.1. it’s not the only project i’m working on, and the time leaves to me is short.
If you do think handyCalc is useful to you, you can donate this project. or, you can simply rate a FIVE STAR in the market to make it known by other people.

Yeah this is crazy, this calc should be in android, but I dont know why? I saw the list and I’m sick on those help, emergencies apps.
I will tell you to port on Iphone, maybe you will find more respect, but leave it for android too.

Keep on working

Hey there,
It’s a shame you didn’t make it on the list, but I have an offer for you. I’m the owner of AndroidBoards.com, you may have run across it in your Android research. I am doing a series of interviews on great apps that missed the ADC list. I would love to feature yours, as it’s definitely that I feel should have made it. Please e-mail me at admin@androidboards.com if you’d like to be featured. I’ll send you some interview questions and we’ll go from there.
Sorry to contact you through this, I saw no e-mail address on the site that I could get in touch with you with.

Hi mmin,
I tried installing your application but i am getting the following error:
” Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED]”
I recently upgraded to the latest SDK. Do you thing it can be because of that.
Could you update the .apk file with the one that works on the latest SDK.
BTW, your calculator ROCKS!!

Awesome program. I was contemplating writing my own graphing calculator or porting something like gnuplot or octave to Android, but this is much better than I would have thought to do–the automatic solving and suggestion of actions on what’s written is really convenient.
I’d like to see it go open source. There are some additional features I’d like to see (and could submit patches for): support for non-decimal bases (hex, octal, binary) and the multiplication symbol on the G1 keyboard (×). I could also help port it to iPhone as I have some experience writing iPhone programs and porting to iPhone.

Awesome program, will you make it open sourced?

Great calculator! I donated you $10! Thanks
(would be even greater if it was open sourced)

I really enjoy this aplication, Its one of the bests I’ve seen on the market at the moment. Anyway I would like to suggest/beg for a change or new implementation. I miss somehow some small feature, wich is work in binari, making binari calculations, at the moment the calc just makes unit conversion, would be awesome if you could work on it to make it make some basic operations on binari. Anyway, awesome job with this little tool. Thank you very much.

I’m absolutely excited about your app. Can’t believe this isn’t included in the standard Android distribution already.
Kudos to your great work, keep it up!

This is an amazing app.
To be honest I hardly use much of the extended functionality, but still have it on the front page of my Hero to showcase to people how powerful Android apps can be.. “Solve for x”.. Awesome!
I can’t believe you didn’t make it on the ADC – clearly gimmicky social, networking and shopping apps do a lot better than an excellent working tool such as this! Keep it up!
All the best,
Nikos
