5.3 App Features
The Ovutek Fitpal app offers several features to enhance your health tracking:
- Goal Setting & Progress Tracking: Set personal weight goals and monitor your daily, weekly, and monthly progress through intuitive charts and graphs.
- Unlimited Users Mode: Allows multiple users to create individual profiles and track their data separately on the same scale. Ideal for families.
- Family Mode (Baby/Pet Weighing): This feature allows you to weigh a baby or pet. First, weigh yourself, then step off. Next, pick up your baby or pet and step back on the scale. The app will automatically calculate the baby's or pet's weight by subtracting your weight.
- Zero-Current Mode: For individuals who are pregnant or have implanted medical devices, this mode measures only weight and BMI, disabling the bio-electrical impedance analysis for safety.
