I have used five different weight apps and this is the best in my book. The design and data are structured in a way that allows a user to zoom in / out to better understand trends. I also appreciate the ability to set two decimal points so that the most granular weight data can be captured - would love to see an AppleWatch complication that displays this.

Some issues

Personally I like this app. I don’t have much to say about it. The only thing I am having an issue with is that I’ve been trying to delete some old weights from my history and they disappear for about fifteen seconds and then come back. I don’t know if it is just a bug or if it’s programmed into the app. But other than that I like this app. One thing I would add would be an option to add photos when you document your weight.
Great app for keeping track of weight loss.

If your looking for something simple and easy to use this is it. Best of all it’s free and no ads. Keeps track of weight and BMI. Graphs weight and sends it to your Health app on iPhone. Would like to see iCloud sync with iPad and % of weight loss but not a deal killer just would be an improvement since that’s how I kept track in numbers app.
Does exactly what you want it to

This app makes logging your weight faster and easier than any fitness app I’ve used. The charts are great and the interface is intuitive. I’ve used noom and myfitness pal and still have used this to log my weight the last few years.
