Seconds, minutes and hours have no reasonable maximum.

You can enter 555:444:333 and it will convert it to a true h:m:s value where seconds and minutes each can't be greater than 59. Quite a useful conversion tool in this way. However it's main purpose is to sum time values, for example the times of tracks on a CD or mp3 collection. Or the hours worked on a project. There are unlimited ways this kind of tool can be helpful in daily use.

Just enter what you want and see what happens. there are plus and minus buttons which act both as indicated and as equals keys. And of course as a convert key since if you enter something non-standard like 90:90 it will convert that as 90 minutes + 90 seconds = what standard format in hours:minutes:seconds. I hope you like it. please submit bug reports and feature requests, other than the one known about (screen rotation).

Requires: android 1.5 onward (developed in 1.5 emulator with 1.5 SDK, used regularly on 2.1 OS though for real world testing).


TimeCalc 1.2 seem to be the latest available version. Below you can find file(s) assigned to this version:

Description/changelog of TimeCalc 1.2:

Changelog of version 1.3:

fixed rotation bug
made fonts much larger
added some colors to group button types together
added subtraction

Note: negative values aren't yet supported, so if you subtract a greater value than the current total it will just go down to 0:0:0. No warning of anything different happening is displayed, use common sense.

Rotates ok but help text is hidden in 320x240 screen in landscape view.

Not tested on larger resolution screens.

Earlier versions of TimeCalc may not have had their version number properly configured, so you may have to manually delete older versions before installing this one if you try installing but it finishes with an "application NOT installed" message. Otherwise there is no reason why you can't install this over top of an old version.
