Track your nutrition, right inside Google Sheets.
MacroLattice is a lightweight diet and macro tracker that runs as an add-on for Google Sheets. Log meals, count calories and macros, and watch your weekly balance update automatically — all without leaving the spreadsheet you already know.
Everything you need to stay on track
Built around the foods you actually eat and the goals you set, MacroLattice turns raw logs into clear, actionable summaries.
Food & macro logging
Register your foods with per-100 g nutritional facts and log them by meal, grams and time of day.
Weekly balance
A stacked weekly view shows daily calories and macros against your targets, plus exercise and activity.
Your data, your sheet
Everything is stored in your own Google Sheet. No separate account, no third-party database.

Is it free?
