Game Changer

This app changed my life. After about 3 months of rigorous exercise and changing my eating habits, I had not lost any weight. I did see a little tone difference in my muscles but the scale was not moving. In a moment of desperation, I started searching the app store to see if there was an app that could help. I downloaded Oatsy and instantly fell in love. I immediately saw what I was doing wrong. Although I thought I made healthy diet changes, it still was not enough to achieve a caloric deficit. It is crazy how food that seems so benign could have such a huge negative impact on one’s weight loss goals. Small snacks like hummus and crackers, a few whole eggs and not egg whites, or maybe that small bowl of Special K before bed could all make the difference between weight loss and weight maintenance. I would have never known had it not been for Oatsy. 3 months later, I have achieved my goal of losing 1 lb per week :-) Forward and Onward!

Free and powerful

I was looking for a free macro tracker and this is surprisingly good, it has the basic macros and not much more, the food catalog is good enough for me I have had to create some new foods but that is easy enough i like the fitscore, and the weight tracking, my only complaint is in the basic interface, there are some glitches, or annoyances, some icons are low resolution with rough edges, the birthday roll wheel does not show any numbers so that is not great, and the underlying text when creating a food is way to light, but other than that this is a great value app!

Great app for features - needs slight fixes

I just updated my app today and it was working fine for me and I loved how it was my own personal calorie tracker but it deleted all of my data after I updated the app. I had my own meals and drinks that I had custom made and everything was deleted and now I have to start fresh again and I feel like I’m less motivated to sticking with this app even when I know it’s features are great! It freezes on me quite often and sometimes I have to close the app and relaunch it to create another custom meal.
If there could be a section to add drinks that contain calories as a new section such as my morning coffee instead of having to put it into breakfast that would be better.
