I have 2 weight tracking apps, but this one is my favorite! I love the encouraging messages after I record a weight. I love seeing my progress on a graph chart. The chart also allows me to choose if I want to see the last week, 2 wk, 1 month, 6 mo, 1 year or all time. I love seeing my goal, beginning weight, and weight lost immediately on the dashboard. The BMI and fat % are helpful also. There are more features, like the ability to upload pictures, but I don't use those features. Thanks!

Thank you so much Katherine for the amazing 5⭐ review 🙏💛 I’m glad the app helps you track progress and stay motivated! I just launched a new game Tap on Time 🎮 (tapontime . app), 5000 gems free for new players this week. For ideas or questions don't hesitate to write to me at contact@selantoapps.com

A pretty nice tracker, but the ads in the free version are intrusive. They're small, but they dangle (yes, they "hang" and wiggle) in front of the features you need to use. And it notifies you of silly things (with another intrusive large red dot blocking buttons) like how much weight you're down--after you just left the app and already know. I just wanted a simple, easy to use free weight tracker app, not a coach or cheerleader. This one is fine-ish, but I'm gonna keep looking.

Thank you for your feedback. For the price of a coffee you can remove the ads and support us. That will save you time and will also get you a better app because we will be able to keep improving it 😁

Simple and easy to use with stats on the same screen as the graph, which is convenient. It would be nice if the graph could show weight projections based on personal average (perhaps in a different color) to view an approximate date of reaching goal if rate were to remain the same, or projected weight by a certain date if rate of loss remained the same as personal average. Thanks for considering this!

Thank you for your feedback! The Trend and Advisable graphs are actually part of our Body Diary app's premium features which shows weight projections as you mentioned, although we don't have different colors available yet. Still, we're thrilled that you liked our Weight Diary app. Don't forget to email us if you have more suggestions 😍
