hRange | a 5k automatic heart rate trainer that works with Polar, Garmin, Scosche and MIO bluetooth monitors!

hRange makes sure that youll never run too fast or too slow while training. This app uses a heart sensor to understand how tired you are and through audio cues it tells you if you need to speed up or slow down. Discontinue any exercise that causes you pain, severe discomfort, nausea, dizziness, or shortness of breath and consult a medical expert.
