If reading this article, you suddenly decided that all these applications are more troublesome than useful, then I can assure you that you should not jump to such conclusions. The simple and convenient Best Before program with a built-in barcode scanner allows you to do without the usual hustle and bustle: the captured barcode is automatically added to the application database along with the exact product name and expiration date. In addition, Best Before can calculate the average shelf life of this or that product and warn you when it is better to give up using it. The notification system is colorful. You can download Best Before for free (by the way, the iOS version is also provided).
