I use Runkeeper, also. I have been using it for almost two years. I used it for a very long time, then a few months ago started having trouble with it being REALLY off. It was 100% related to a problem with my phone's GPS. I had to have some settings changed/reset for my GPS signal, and it's been accurate again ever since. The accuracy definitely depends on the GPS, which the program relies on.

Coral, I'm not sure about the iPhone version, but if you set Runkeeper up to signal your intervals (slow, steady, or fast), you'll get your splits for each segment in Runkeeper. I'm not sure if this link will work, but this is my very first C25k run, so it's got a 5-minute warmup, 5-minute cooldown, and alternating 1-minute and 1.5-minute segments, which were my run and walk intervals.

The accuracy of your tracker may be related more to your phone's GPS and not necessarily the App in question. I used to have an Android and used RunKeeper, but the GPS was way off. I tested it with mileage markers and my Garmin and both told me I was going further than my phone was (I also noticed that it kept saying I was running really slow when in fact I wasn't). But I upgraded to an iPhone and installed Runkeeper again, and boy oh boy, is it accurate now. So you could try to install a different app on your phone but it might not fix your problem. In any case I do recommend RunKeeper but the only thing I don't like about it is that you can't "lap" when you want, for instance, with my running and walking intervals, I like to hit the lap button on my Garmin GPS watch with each interval so I know what my actual running pace is for each interval. With Runkeeper there is no lap button and all it gives you is your mile splits.

I use Runkeeper for my runs and love, love, love it! It can track other forms of exercise, too, though I haven't really used it for anything but running. (Looks like you can log walking, hiking, cycling, mountain biking, downhill skiing, cross-country skiing, snowboarding, elliptical, skating, swimming, rowing, wheelchair, and "other.")
I haven't had a whole lot of success with pedometer apps on Android - their accuracy is way off even with known distances.
I use the mapmywalk app, which is pretty accurate. Instantaneous speed is a bit erratic (probably the inherent limitations of GPS), but the average speed is spot on with what I know from other methods.
