История покупок is a useful app for tracking personal expenses and income. The app requires registration with a receipt-loading service or using an existing account, and then simply scanning the QR code on the receipt with the phone's camera. The receipt content will be requested from the Federal Tax Service and saved in the personal purchase list.

If the QR code on the receipt is damaged and cannot be read, users can manually obtain the receipt from the Federal Tax Service using the required details. If a receipt is lost and not scanned in time, the purchase can be created manually.

Users can create expense reports with detailed breakdowns by categories, stores, and individual products. The app also allows for analysis of price dynamics on previously purchased items, grouping of similar products, and budget planning for the most important categories.

The app also offers the ability to import receipts from the official Federal Tax Service app and export data to CSV and third-party apps in JSON format. Overall, История покупок is a convenient way to monitor personal expenses and income.
