Napkin Math

Meet Napkin Math

Napkin Math is a food journal for people who want to understand their eating habits over time. Meals can be recorded with a photograph or a short description, creating a visual history to revisit across days, weeks, and months. The app emphasizes reflection on food choices and routines rather than detailed calorie counting.

Users can look back at entries when considering changes in energy, appetite, digestion, or other observations, and use the record to support modest goals such as more consistent meals or a different mix of foods. Available for iPhone and Android, it provides AI-assisted suggestions and food collections. These observations can support personal reflection, but they do not establish medical causes or replace professional advice.
