An application that allows you to save a photo of things before moving can be helpful in several ways:

Inventory of belongings: The app allows you to create an electronic inventory of your belongings by taking photos and saving them in the app. This can be particularly useful during a move when you need to keep track of all the items you want to take with you. This way, you can ensure that you haven't forgotten or lost anything during the moving process.

Insurance and claims: In case of loss or damage to your belongings during the move, the photos saved in the app can serve as evidence for insurance claims or filing complaints with the moving company. You can provide proof of the condition of the items before the move and compare it with their current state after the move.

Organization and planning: The app can help you organize and plan your moving process. You can create albums or categories for different rooms or types of items to have a more structured approach to packing and unpacking. You can also add descriptions, labels, or a to-do list to each photo to ensure you don't miss any steps.

Overall, such an app helps you save and organize information about your belongings, streamline the moving process, and provide additional guarantees.
