    Can someone recommend an app that would let you add a string of times?




    And give you a result in hours:minutes:seconds format like this?

    01:04:04
    03:55:56
    ----------
    05:00:00


    Thanks. Seems like a simple enough tool but with so many different calculators in the Market, I can't seem to find one as simple as this for adding times together.

    Adding times by hand is a pain. First you have to add all the seconds. Then divide by 60, carry over to the next column leaving the remainder, then repeat for minutes, etc. This would be so trivial for any calculator to compute, but I can't find a decent app for this anywhere!

    I really need one of these, too! I'm a scuba diver and need to add a list of dive times. It's a pain to do it the 'old way'.

    edit: updated to version 1.2 (bigger fonts, colored some button text, fixed rotation bug, added subtraction (but can't display negative values, just goes down to zero in that case, keep that in mind).

    version 1.2 fixes a screen rotation bug, makes fonts much bigger, and adds subtraction (although it won't go negative, just down to zero, keep that in mind when doing subtraction).

    Please download from: AndAppStore : TimeCalc
    there's a barcode installer there as well.

    original message:
    New App: TimeCalc - Time addition calculator (hh:mm:ss etc)
    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 jsut 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.

    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... :-)

    also can subtract time values.

    Cheers, have fun people.

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

    filesize is all of 13 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.

    Don

    version 1.2 fixes a screen rotation bug, makes fonts much bigger, and adds subtraction (although it won't go negative, just down to zero, keep that in mind when doing subtraction).

    there's a barcode installer there as well.

    If subtraction is a high priority for people then let me know. this thread or email support is worth a shot, but I did this for myself mostly so I can't offer great support. I'm uber busy with 3 kids, a wife, a dog, a full day job, and a second evening career. But I DO want to help people out so will certainly do my best to add what I can when asked!

    Time Calculator Free and Time Calculator Pro version 1.2 now available in Android market with much better looking UI with bigger buttons and a lot more input options.

    Not all options are available in the Free version (Pro is only .99 cents and enables all input options) but here is a listing of some of the input options:

    Input Examples:
    3:10 + 2:30 =
    3:10:05 + 2:30:10 =
    9:15AM to 11:30AM =
    9:15:10AM to 12:15:10PM =
    9:15AM to 12:15PM + 3Hrs =
    9:15AM to 12:15PM x 3 =
    3Hrs 10Mins + 2Hrs 30Mins =
    25Mins 15Mins 45Mins / 3 =
    Other valid combinations also possible...

    Please give it a try and let me know what you think.
    Please do email if any issues using it!
