I like iHealth which track my weight and present it in a graph. I recorded my weight from time to time and use iHealth to keep track. I hope following features / functions are available in iHealth Fitness. Allow user to add new category, for example "Push Up", then I can record number of push up I do in daily basic. Another category, like "Plank", then I can record amount of time I do plank in a daily basic. I think this should be quite simple as all the Application logic is already in iHealth. But I just cannot find any Apps that can do this.
