No. You can use Amissa without a wearable device.
Helpful Details:
The app works on its own, allowing you to log symptoms, track mood, record lifestyle factors, and view your health trends. A wearable can add more insights—such as heart rate, sleep quality, or activity data—but it isn’t required. You can get value from Amissa whether or not you choose to connect a device.
Next Steps / Where to Go:
If you’d like to enhance your experience with wearable data, Amissa supports Apple Watch, Oura Ring, Garmin, and other devices that connect through Apple HealthKit. Setup instructions are available in the Help Center.
