Opson is a food log with no ads that you set up your way. Count every calorie, aim for a range or a deficit, follow only your macros, or log without seeing a number at all.

Search over 3.7 million foods from the USDA and Open Food Facts, or type what you ate in a sentence and Opson finds each food. Copy yesterday's breakfast in one tap, or save the meals you eat every week.


Aim for a range, or for a set deficit under what you burn. Not every day is the same, so training days can have a goal of their own and the rest of the week another.

Pick one of ten ways to track. Nutrient focus hides calories and shows your macros as fill bars, and Blind takes calories out of the app completely. After that, change any single number on its own.


Trends lines each day up against your range. There are no streaks and no warnings about calories left. Skip a day and it's a gap in the chart, nothing more.

Opson doesn't show ads or sell what you eat. Your log lives on your phone and syncs to your account, and you can export it or delete all of it from the app.

Leave your email and we'll send one note when Opson is in the App Store.
