UI Design - Plankr app

Plankr app - An app designed for planking fitness training in 2014. At that time I struggled on weight control and found that planking was an effective way for core muscle training. I outlined my needs as a target user's needs and did the wireframing and UI design in my spare time between projects. It was planned to be developed as an iOS app, but because we didn't have enough developing resource at that time, it only remained in concept.
