Yes, there's an ab for that: iPhone (News - Alert) fitness application developer Abvio has announced Runmeter 2.0, a running application for the iPhone 3G/3GS. 

The app turns your phone into a GPS stopwatch, if you think such a gadget would help you run faster and increase endurance, well, put this on your list for Santa. It has Twitter text-to-speech, so you can get coaching and even more distractions while running.

It's one of the first iPhone applications with the ability to start or stop the application from Apple’s (News - Alert) earphone remote. It allows direct Google Maps sharing via e-mail or Twitter -- "Let's see, Nelson Avenue... whoa, how'd I end up here? Must've missed a race marker a few miles back..."

Abvio bills Runmeter 2.0 as "battery-friendly -- runners can train for up to six hours without recharging or using a battery extender."

Steve Kusmer, co-founder and CEO of Abvio, says users can control and use the app "while your iPhone is sleeping in your pocket or armband.” It also has maps, a calendar of all your runs, graphs of elevation and pace and spoken announcements of your statistics as you run.

Runmeter 2.0 requires no Web site log-in or monthly subscription and is ad-free. It's available now from the Apple iTunes Store for $4.99.

Abvio's a privately held, San Francisco-based iPhone application developer building iPhone applications for fitness.

Last month TMC (News - Alert) had the news that Austin-based VidaOne, a vendor of diet, fitness and health mobile applications, announced that its new iPhone and iPod Touch fitness application MySportTraining was featured on the Apple App Store What's Hot List.

"We are very proud of this distinction given that the application was first released on the App Store only one month ago," Jean Louis Gareau, president of VidaOne, said at the time.

MySportTraining has been a fitness application for Windows Mobile and Palm OS devices for ten years, and is now available for the iPhone and iPod Touch. It offers what company officials describe as "comprehensive tracking of both cardio and strength training workout," and includes such features as live GPS workout recording, cardio intervals tracking and an interactive muscle chart to suggest exercises per muscle group.

Users can customize the application to their needs by adding their own activities, exercises, intervals, routes and locations, and can review their past efforts using a detailed calendar as well as numerous reports and charts.
