If you're on the lookout for solid, consistently updated fitness apps for Windows Phone, your options are now a little slimmer. Runtastic quietly posted a notice to its website (via WindowsArea.de) announcing that it is "phasing out" its Windows Phone apps, and will no longer be providing updates on the platform.

Runtastic has ceased updates to its Windows Phone apps

From Runtastic:

Unfortunately, Windows Phone has far fewer users compared to Android and iOS. This means that the market is relatively small. It is always a good idea to check out the future possibilities of a platform before purchasing a phone.

Like every other company, we make our decisions based on where we see the greatest potential. At the same time, we are one of the few companies that has developed apps for this platform. Naturally, we also want to offer our Windows Phone users the best possible products. However, we hope you understand that our priorities are set according to platform and market and that from now on we will no longer be updating our apps for Windows Phone.

It's unclear when the notice was posted, but it looks like the last update to land for Runtastic's main apps came sometime in late September. As of right now, Runtastic's apps are still available in the Windows Store, but a lack of updates going forward could pose a problem should any new app-breaking bugs surface.

Runtastic was one of the better fitness apps for Windows Phone, so it's sad to see support dropper. That said, there are some alternatives, such as Caledos Runner and Perfect Workout, that are worth looking into. And of course, if you have a Fitbit tracker, you can already take advantage of the Fitbit app for all of your runs. Are there any specific fitness apps you'll be turning to?
