The folks at RunKeeper Pro must’ve liked what they saw when they offered the application for free before, because they’ve just announced a permanent price reduction to $0. If the trend is anything to go by, RunKeeper’s thinking more about their longtime revenue goals than the money they make for the app up front. It’s a business model that’s become almost necessary in the Android market considering how hard it is for paid apps to generate revenue. They claim many new things are in store for 2011, so go ahead and download it now without worry of it ever getting another price hike. [via LifeHacker]
