App crashes freezes and performance lags
“I’ve been using this app for over a year and it has a lot of potential, but it’s currently held back by several frustrating bugs and poor design decisions that make daily use much more annoying than it needs to be. Major Issues: • History & Search is broken: The recent…”
Food entry UI difficult or broken features
“I do like this app and I really enjoy how the macros are at the top, broken down I don’t have to go look for them. Things I’d love to see implemented. *Adding a recipe by ingredient. Currently I have to go to MFP to put a recipe in, get my macros, and then add to this app which…”

App accuracy and database food information issues
“Weil the app projects to make things simple It really is not. AI is horrible. You end up having to ChatGPT everything anyhow. You put a recipe in making your life simple so you can just click the saved recipe and add it to the meals, but it keeps changing the macros on calories,…”
