I love this thing. It disappeared for a while and kept crashing a while back and no one used it so maybe that was why but now it works properly and you can even view ahead of what weight o expect on a certain upcoming date. I love the simplicity. Red or green. I love that it's only telling me one thing: whether to watch myself and tighten the screw a bit more today on my diet or if it's a maintenance day and can have a bit of extra, chocolate or something. I love that I don't need to enter food or focus on calories or other random stuff. Only have to focus on my daily conscious effort on my diet with this app. Good by me, I got sick of all the calorie apps that have way too much going on and you forget to focus on conscious effort sometimes.

Perfect but for one tiny thing

The font on the home screen, where it begins, “You have lost. . . ,” needs to be bigger or bolder, or perhaps both. The contrast between the white font and the light green background is not extreme enough to be easily read at its current font point. In contrast, the title at the top of that sane screen (Line Diet) is easily read. Creators, think about it.
