I used the Christian Indie Tracks from: http://www.buriedtalentsband.com/C25K/
The music helps me to relax while motivating me to keep running.

I tried another one (Podrunner?), but it set my teeth on edge.

My phone isn't terribly smart, so I use podcasts. My fave has been the series put out by NHS (http://www.nhs.uk/Livewell/c25k/Pages/couch-to-5k.aspx). I like the music, and love the voice commentary. The encouraging comments are not too frequent, and timed perfectly. I like that she throws in some running tips each week too. Also, I do fancy that British accent.

same here. first time i listened to it at home i thought i would hate it, but nobody made a metal version so far haha.
once i start running i dont really hear the music anymore, so its okay

I use Run Double for Andriod. It comes with a free two weeks and after that is is $1.60 and it is well worth it. It lays out the schedule you'll be running, shows your stats at the end and uploads them to the Run Double website in your account. You can use your own music playlist or internet radio like Pandora. It has remained glitch free and I still use it for 'fun runs' and will be using it for the 5k to 10k training. By far the best app on my phone (aside from MFP, of course )

Highly recommend C25K by BlueFin, 69p gets you GPS, customisable playlists, run pace, walk pace, average pace, distance, current pace, weight tracker, calories burned. I graduate next week and have already dowloaded their Bridge to 10K app. They also do a C210K app.

I just used the free "A HIIT Interval Timer" for my Android and plugged in the splits for training session myself. Can use it simultaneously running Endomondo (for GPS to get distance, calorie burn, etc., speed, split-times, etc.) and any type of music you want (Pandora, Tune-In Radio, your own playlist, whatever).

No voice. It just starts a warning countdown and then dings when it's time to change what you're doing but, obviously, if you're running, it's time to walk or vice-versa.

I use the zenlabs app on iphone-its good on the treadmill but the pause button sometimes get pushed by accident when out and so sometimes the lady doesn't talk to me!!

if the lady isnt talking to you usualy means you have hit the silence tab on the side I lock my phone down when I am running so no buttons get pushed

I do all of my training on a treadmill. I'm up really early (4:30 am) and it's way too dark and dangerous for me on the streets. I've been using the C25K Free from Zen Labs app on my Android for 6 weeks and it works just fine for me. I can play my own music; the voice prompts pause what I'm listening to to tell me to run, walk or cool down; It tells me when I'm halfway done; and it's free!!

The only issues I have with it are that sometimes the voice is too quiet and I miss my cues (usually only when my song was really loud and I had to turn the volume down) and one time it quit on me and I didn't know it... so my last 5 minute run before the cool down turned into almost 7 before I realized it. Oh! and the ads are kind of annoying but not too bad.

I use Run Double on my android phone.

I use it with Pandora or you can use it with your own playlist. When it comes time to switch intervals it pauses my music, vibrates my phone and the voice come on telling you what's next followed by a summary of what I just did (miles, pace, etc).

It also has a website that it uploads your progress to as soon as you're done with your run so you can see all the stats as well as a map of where you ran.

The first 2 weeks are free but to upgrade it is $1.60. I felt it was worth it. 80s Pop is always fun to run to on Pandora!

i use this also. i just use playlists from within roundouble rather than bothering with another music app. apparently it will also work with certain HRM's. mine is an el cheapo but it worked with the machines at the gym i went to which supposedly only worked with Polars, so im hoping that it will work with rundouble as well, i just have to put a new battery in it.

my only gripe (and this isnt just a rundouble issue as i had the same issue with runkeeper on my android, and pretty much any other gPS running app on a phone) is that i do an out and back run rather than a loop. so when i get the halfway reminder, i double back and head home. the problem with this is that unless you turn right on the moment of a gps update, your intervals on either side of half way are going to come up short in distance.

I use 10K runner by Clear Sky Apps. I started with the 5K runner free version but it only lets you do the first 2 weeks. When looking to buy an app I knew I wanted to go onto a 10K later or at least have the option KWIM? The 10K runner app has the 5K built in so you do that first. It allows you to play your own music, voice prompts you to run, walk, warm up/cool down and tells you when you are half way done. I chose this app because it looked good and had great reviews. I think it was $2.99, totally worth it. I can also run other apps while this is going and there is no interference. I would totally recommend this one.

iPhone user: I am using the 5K Runner app from Clear Skies. I'm finishing week 7 today. My first 5K race will be next weekend.

It prompts for run/walks with a voice and vibration. It has controls for a music player but I don't use it. Here's what I do:

Start Downcast app to listen to podcasts while running.
Start Digifit app to record HR, calories, GPS map, mileage, etc. **Syncs data with MFP and Fitbit**
Start 5K Runner app for timing and prompts for current training level.
