RunKeeper displays your route using Google Maps and tracks distance, duration, speed, pace and calories burned. You can also input your runs manually (useful when running on treadmills) to add them to your "workout logs".
Since this allows both "GPS" and "stopwatch" mode, and tracking several sports, it should allow you to use intervals in stopwatch mode. I would like to use intervals for treadmill running or stationary bicycle.
You can add several pairs of shoes to this app and select which you are wearing for each activity. It will keep an overall count of a shoe's mileage to help you know when to buy new shoes.
While charts do exist for pace, elevation, and cadence, they're all independent graphs. It would be nice to see pace overlaid with elevation, as some other apps do.
If you are using both intervals and audio stats, and then happen to occur at the same time, the stats are announced first, and then your interval announcement after. You end up starting your interval late, even though it's tracking that interval already.

Stats such as top speed, speed of each interval, fastest/slowest parts of a course, etc. Where applicable, graphs and maps routes will be display for a visual representation.
There are no community features like following another user. Every activity or profile can be shared. Every public profile can be followed by RSS feed.
Endomondo used to be a singular priced upfront paid app with no subscription fee, twice. During the first restructuring, the app was changed on the store, leaving out the people who had paid originally, to then require them to pay again for the new app. After this happened, the app changed again to be free-to-play, dropping features that paying customers had paid for and locking them behind a monthly pay wall. So not only did long time users who paid for the app get ripped off once, if they had paid for the newer paid app, they got ripped off again when the app went free-to-play. This is not a great track record for the service, leaving to question, when is the next restructuring going to happen that may potentially take the money of paying customers without delivering the service promised.
Endomondo displays your route using Google Maps and tracks distance, duration, avg. speed, avg. pace, calories burned and hydration. It even tracks what music you listen to while exercising (can be viewed on their website).
(Premium) Each interval begins with a brief, clear series of tones that makes it very obvious which type of interval has just begun. (High, medium, low.)
(Premium) version comes with both a few built-in intervals and also allows you to make custom intervals. You can use both time and distance as intervals.
Runtastic is capable of informing users of their pace, distance traveled, heart rate, and altitude, along with a detailed map that is saved into "history".
The completed workout's map is saved along with all of the data collected about the workout. Because of this feature, users can easily track their improvement and accurately set goals.

Zombies, Run! uses a creative story line to help motivate the jogger. A mission is given, which the runner must complete while collecting supplies and running from zombies.
Every workout summary in detail view or calendar overview shows the intensities determined by heart rate, power or speed zones. This enables me to train easier and harder at the same time.
