Of all the 5K apps I like this one the best. Very user friendly, easy to read.
Personalized Voice Coaching
App will alert you, using clear voice, when you need to change pace or when you reach halfway point (plus other configurable options).
Heart Rate Monitor
If you have a heart rate monitor device based on Bluetooth Smart (LE, 4.0), Run 5k will use it effortlessly during the run. You can then compare your pace and HR for each run and as you progress through the program.
Apple Health ready
If you grant access to Apple Health, you can save your workout and heart rate data into it, plus avoid manual input of calorie-related parameters.
iPhone 6 and 6 Plus
Entire app is usable in both portrait and landscape on any compatible iPhone.
If you run with your iPhone in pocket and want to check your progress from time to time – this is for you. Real-time running info accessible from lock screen.
Animated Run View
Real-time visual feedback of your current pace and distance. This feature is based on GPS location services, thus available on iPhones only.
Easy to see current progress and what’s ahead. For upcoming runs, you’ll see the description; for past runs you will see the most important details: distance covered, average and max pace (or speed).
Examine important details of each run - follow the pace/speed changes, heart rate rhythm, how much calories you burned and see the map of the entire run.
Run with Music
Or in silence. Works great with any music or podcast app you already use. App will fade-out the music volume when pace changes are spoken and fade-in afterwards.
Brag about your progress on Facebook, Twitter and more.
Made for Modern iOS
Built from ground-up for modern iOS user interface, with lots of custom animations that help make the app a joy to use.
I like the heart rate feature because it really helps to tell you if you are getting better at running.

Your app has been a constant encouragement on the journey. Took me from nothing to running a 5k. Looking forward to more.
