I bought this app and I really do like it if they fixed a few things, Number one thing is I do a day and a lot of times the next day itll go back a day so I have to keep track on my own of which day I started. Idk if this is a trick to trick people into doing it longer for better results but I have took a picture to see my ending results and I will write a review at the end of them.
