Your unique Activation Code is essential for pairing the physical Fitness Snack Lock with your smartphone. 1. Check Your Order Slip The code is printed directly on the Order Slip (the packing list) that arrived inside the shipping box with your lock. • Look for: A 6- or 8-digit alphanumeric code labeled "App Activation Code" or "Device Key." • 2. Pairing Your Lock 1. Download and open the Fitness Snack Lock app. 2. When prompted, enter the code exactly as it appears on your order slip. 3. Keep the lock close to your phone during this process to ensure a stable Bluetooth connection.

If you recently updated your phone's operating system (e.g., to Android 16), the connection between Fitness Snack Lock and your health data source (like Samsung Health or Health Connect) may have been temporarily interrupted. To fix this: 1. Uninstall the Fitness Snack Lock app from your phone. 2. Reinstall it from the Google Play Store. 3. Open the app and follow the prompts to reconnect your health data. This process clears the old connection settings and forces a fresh sync with the new Android system.
