This app is awful. I never write reviews but I hope that I can save others the headache of investing any time in this. My gym uses this, so Ive been logging my info. Its so buggy that it has stopped working twice, requiring me to reload it. It can not do math and cant follow the goals Ive set. I had 1/2 pound to lose in 10 days to reach my goal, and it told me I was "behind"...?? It has never worked as promised. If you are a trainer, do NOT use this for your clients!
