A few months ago, I launched a running app called Fyrefit. The goal of Fyrefit is to help you keep your pace by providing a coach voiceover that tells you to speed up when you start to slow down. As long as you keep up your pace whenever the coach tells you to speed up, you are guaranteed to reach your goal. This is perfect for training for a race or just making sure you are progressing.
