Ubersense claims that their updated app (for sport coaching video analysis) will automatically record at the highest frame rate possible on your phone. My iPhone 5 does 60 FPS in the SloPro app but only does 30 FPS in Apple's native app and in Ubersense (despite what Ubersense claims). Very frustrating. SloPro is free by the way. You only need to pay if you want to disable the watermark and export the videos.
