Feature Request: More time options

Thanks for developing this great tool. I use it to track where I was when I’m at work.

I’d like to have more control over the Time Filter. One minute leads to quite a lot of inaccuracy. The next smaller option of 10 seconds works flawlessly. But it is an increase in tracking frequency of 6 times. This leads to my phone using a lot more battery. I guess that something in the middle of the two options would be enough.

I would be happy with a 30 seconds option, since that cuts the battery consumption in half and would probably be accurate enough. Maybe you can even add an option for us to type in our own time.

Thanks a lot
