macOS need help with running log program

[twoodcc]

so i'm trying to make a running log core data application. is there a way to take all the values in one column and sum them in another column or somewhere?

also, can i take the miles that they've run and divide by the time? even if the time is a string data type?

or should i not be making a core-data app?

thanks in advance

i take it not many people make a core-data app anymore. what would you recommend for a mac running log?

I am actually in the process of writing one for people that use various heart-rate monitors, gps watches and other speed and distance tracking devices (like Nike+iPod). I have nothing to show yet, but you might find one of the following apps suite your needs:

Mac native:

* http://www.montebellosoftware.com/
