I'm Gene, and I built MyFoodManager because the things it takes to feed a household usually live in five different places: recipes in a binder and a dozen browser tabs, the week's plan in my head, the grocery list on the back of an envelope, and no idea what anything actually costs at the stores I shop.
Here's how I use it. My own recipes live there, more than 40 so far, some imported from websites and some scanned straight from paper. I plan the week's dinners, let it build the grocery list sorted by aisle, and check off items in store mode with one hand. When I spot a price on a shelf tag, I snap it, so my price book stays honest, and before a big shop I check which of my stores is cheapest for that list.
The guides on this blog follow the same rule as the app: practical, specific, and checked against primary sources like the USDA and FDA. If something here is wrong or unclear, write to me at support@myfoodmanager.com. I read every message.
