[Android Apps and Games] dkelley:
UPDATED TO VERSION 1.2 (NOTE: I'd put this in the market but I don't have $25 or a credit card!)

new version 1.2 released

summary of changes:

- fixed screen rotation bug (running total and current entry are remembered when screen rotates)

- much better layout (fonts are far bigger for example)

- major new feature - minus calculation. You can now add AND subtract time values. It can't yet handle a negative result so if it will go negative it just displays 0:0:0 (time equivalent of zero).

back to the original posting:

Out of the desire to write an app for android finally, and one that hasn't been done yet (at least not free that I can find on the market currently), and out of a necessity for just this kind of app since I work in music often and calculators are useless for hh:mm:ss types of addition, I decided to write what I feel is a truly useful utility.

of course it's free - but no I'm not releasing the source code. It sucks, and I'm just learning android development, and I just want to get this out there on the market sometime soon (but don't have the required $25 to pay for that yet!)

so here it is. I hope people find this useful.

Name: TimeCalc

What it is: Time addition calculator (hh:mm:ss etc)

requirements: Android phone. I developed it on 1.5 devkit and it runs fine in 1.5 emulator. on my 2.1 hero phone (official 2.1 taiwan rom) it runs perfectly too.

What you can do:

type in a time as seconds, minutes:seconds, or hours:minutes:seconds.

now hit the + button (which is plus or equals depending on how you think about it LoL). It adds the time you just entered to the total time value displayed. If that was your first entry, it just makes the total time value equal to what you entered.

Do this again. new total time.

Now it also does subtraction.

times are always displayed in h:m:s format. you can mix and match entries - 5555:555 will be 5555 minutes and 555 seconds. if you had no total before and hit the + button it will now display 94:44:15 in the total box (I got that from running my app on my phone so I hope it's correct LoL... :-)

Cheers, have fun people.

I've seen lots of requests for this all over the web.

filesize is all of 13.2 kb. no menu, nothing. just run the app. no custom icon yet. no versioned yet, but hell it's alpha code. however it DOES work and I just used it for cd track listing summing for one of my jobs.

I made the buttons sort of big so typing should be easy. it's go ZERO extra features. when I have more than 2 hours to write an entire app out of nothing I'll add more too it, so I welcome bug reports, feedback, ideas, and so on please!!

TODO:

- I think it would be great to add multiplication. multiply a bizarre time value by 3 or something and it gets complicated to do in one's head, might as well use this calculator. For example: Manager has 7 human resources who can each dedicate 5 and a half hours to a project. How many hours will that give the manager? Stuff like that could be helpful.

- I am considering adding an additional spot for days. I suppose it could be useful. However it gets complex - days can be many things. 8 hour work days (which aren't always even really 8 hours), 24 hours, 16 hours (awake time), etc. So I have to think about this one.

- copy to clipboard (could be nice I guess)

- a custom icon (might as well)
