My name is Anna Collis, based in Hertfordshire just north of London. I am looking for someone to help me create a fitness related app for phones. This idea I have hasn't been done before and I think there is a real gap in the market. I want it quite simple but effective- it focuses more on HIIT training (High Intensity Interval Training) which is becoming more and more popular. This app will be great for those who can't afford a PT regularly!
