This kit includes the use of the FnT app (Android or iOS (coming soon)) with the tags (8), protective covers (8), and an alignment tool. The tags are what link the leftovers and the database. Without subscriptions, the App is fully functional; however, the database is stored on your device, the data is not family-shareable, and is susceptible to loss.
Note: this package must be purchased either with or before any additional FnT tags, protective covers, or subscriptions.
