Runner Lite
I bought this app as a complete beginner at running, and it has really really helped me! Intervals are so much better than trying to run for 10 minutes on your first attempt (that first iPhone-less workout almost killed me), and its great not to have to keep an eye on your watch to know when to switch. I took some advice from a friend whos an experienced runner, and she told me the pre-set intervals are not ideal as the walking intervals are too long (apparently 1 minute is plenty), but it was easy enough to customise my own runs. At least, it was before the upgrade to version 3.0.0 of the iPhone software, but I hear theyre working on getting the customisation working again.
I built up from 7.5 minutes total to 35, and then upgraded to the full version of the app as I wanted to be able to track distance and speed as well as time. But the Lite version is a good initial investment. On days when my husband borrows my iPhone, I refuse to go running without Runner!
