Love this app because it's SIMPLE. It's not a life tracker, no. It's not myfitnesspal, it doesn't track food or macros or exercise. It just tracks weight and calories: the two most important things for anyone trying to lose weight. I like it because it clearly shows my current weight and list all the weigh-ins from the past weeks so I can see my progress. It also shows me my average calorie deficit over time based on the weight I've lost and my average weight lost per week. Tracking my life can make me crazy, and with this app I can just track the fun stuff. It is a tool that gives me motivation to keep working hard so I can watch the number on the scale go down from week to week. Great app!

No fuss, perfect


I don’t want to make weight loss more complicated than it is. Eat less, eat right, move more. Not interested in logging every calorie & measuring my food down to the last gram. This app is perfect for visually seeing the ups & downs of your weigh-ins over a long term period helping you see how you’re doing towards your goal. I love how much information it gives, yet is just so simple. Good job to whoever created this! Thanks!

Better than MFP for data

I downloaded this and initially didn’t care for it, but kept it. And I am GLAD I did!!! I love the way you can access the calendar to see when your weight has gone up or down. It also shows the lowest and highest weights you’ve ever entered, which other apps fail to do!!! I’ve had this for years and can’t say enough wonderful things!!!
