Android interval timer

[j0nharris]

I'm trying to find a good run/walk interval timer for my Android phone.. I wear my phone in a waist pack, so I need something that will switch modes automatically.

Any suggestions?

Thanks!

I used to use the HIIT timer. 

Now I use the Jeff Galloway run/walk timer.  It's only $19.95. You can also buy a Gym Boss on Amazon for $22.95. They are the same watch, but different colors. It has a clip on the back that works.
