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.

This app is so simple and so effective! I am loving it as I’m using it now on my weight loss journey, but I’m thinking it will truly be a “most used tool” in maintenance, when it gets so hard not to let those pounds creep back on. I really do foresee this being something I use daily for years to come, so I hope it stays available. It works great. No glitches. Yay, for the simple ultimately helpful idea of this app! Thank you!

It’s great, but a little hard to read,

I love an app that does one thing very well - and this is that sort of app. Having a visual of my accomplishments and my stumbles helps to keep me working toward my goal - which is the whole point. So the graph page is perfect. But I agree with the reviewer notafatso that the font where you enter your daily weight should be larger and of greater contrast. It’s almost as though the designers *intended* to make it hard to read. Why make the font so tiny on a page where there is more than enough room to make it twice as large? Enlarge the font and you’ll have created a 6-star app!
