I've just been using the free version while running up and down the street.
The extra functionality like voice overs, iPod integration, challenges, and more were extra add-ons for like $3-4 each, and I think the pro app which included them all was more like $8-9 (which included all the add-ons)
So for me the $1.19 deal was great!
Edit:
Some official description of the app:
Here are some of the amazing features of runtastic PRO:
✔ Track exercises via GPS- Automatically records time, distance, calories burned, speed, elevation and more!
✔ View your current position and route on map.
✔ Training diary- History of your exercises
✔ Sexy voice feedback in both English and German
✔ iPod integration – Listen to your favorite music during training
✔ Competitions- Challenge your friends and let the voice feedback tell you if you're leading. (CAUTION – this is addictive!)
✔ Sharing- Publish your activities on Facebook, Twitter, as well as the runtastic sports portal.
✔ Indoor sports- Manual data input offers you the ability to keep track of your exercise regimen such as treadmill, gym training, or yoga.
✔ Lite version available, with in app purchases and paid updates
runtastic PRO also offers the ability for interactive use with fellow exercise enthusiasts by allowing you to challenge your friends and compare your progress to theirs in a competition setting. Proud of your accomplishments? You should be! Share your victories on Facebook, Twitter, and the runtastic sports portal, to inspire and encourage others by your progress, or just to brag a little.
runtastic PRO also works great for recreational activities. Use runtastic PRO while motorcycling, parachuting or strolling; its versatile functions allow it to be the perfect indoor or outdoor, personal or professional companion for all your activity needs.
You can try the lite version if you like, but if you download runtastic Pro now, you get all future updates for free!
Note: Continued use of GPS running in the background can dramatically decrease battery life.
