Select an item to see its price history.
Each entry you log builds a running record. Over time the chart tells you whether a sale is genuine.
Log grocery prices over time. Every entry builds a record you can actually use. No more guessing whether that "50% off" sticker means anything.
Price Memory is a single-page tool for logging grocery prices over time. Each entry records an item, store, price, and date. Over time, the chart shows you whether a price is genuinely low or just packaged to look that way.
All data is stored in your browser using IndexedDB, a local database built into every modern browser. Nothing is sent to any server. Your currency preference is saved to localStorage. Clearing your browser data will erase your records, so use the CSV export to keep a backup.
Use the Export CSV button in the sidebar to download all your entries as a comma-separated file. This opens in any spreadsheet application and serves as a readable backup of your data.
