Simple and effective weight loss tracking.

Simply enter your daily weight and let Weight Diary estimate your progress and how long it will take to reach your goal. No guesswork or calorie counting required.

Great tool for weight loss and maintenance


I’ve heard before that when losing weight it’s helpful to have rewards so you don’t feel cheated at the table. Personally, this app feels like a reward. When tempted, I push through it knowing that I’ll get to see that number go down on the screen. Consistency is a key factor with weight, and the trend line is great for keeping track of how consistent I’ve been, even when I’d like to forget sometimes! :) It’s easy to use and very effective.



I love this app because it’s simple....log your weight...see your progress on the scale...period.
There are so many fitness, health & food journal apps and they are great, but I never liked their weight trackers. When you are losing weight you are excited to log your progress and you want to see that progress in your numbers! This app does exactly that. Period.
Easy to use, great interface and syncs with Apple Health. Love it 👍🏻👍🏻👍🏻

Excellent weight application!

This product has been around for several years and the new revision just keep getting better. The graphics are perfect and simple and the history data is amazing to reflect back on. It works great with the Aria Fitbit Weight Scale and give you the up front data you need to become successful in weight loss and keeping that weight loss off. Great product!
