Smartphone requirements

To work properly with PAGAL LAB Inertia X1, the smartphone must meet some fundamental technical requirements, mainly related to the precision of the sensors and the capabilities of the browser.

Here are the minimum and recommended requirements:

1. Sensors (Essential)

  • High precision gyroscope: This is the most important requirement. The app uses the rotation sensor to measure the oscillation period with precision to the nearest ten-thousandth of a second.
  • Accelerometer: Used in conjunction with the gyroscope to stabilize the reading.
  • Note: If your smartphone does not have a physical gyroscope (very rare in recent models, but possible in some entry-level models), the app will not be able to detect motion.

2. Software and Browser

  • Modern Browser:
    • iOS: Safari (version 13 or higher).
    • Android: Chrome (updated version).
  • HTTPS ProtocolFor security reasons, modern browsers allow access to motion sensors only if the app is loaded over a secure connection (HTTPS).
  • PermitsThe browser must have permission to access “Motion and orientation sensors” (on iOS, explicit permission is asked on first launch).

3. Operating System

  • iOS: 13.0 or higher (for proper support for Sensor APIs and Web Audio).
  • Android: 8.0 (Oreo) or higher, with a recent version of Google Chrome.

4. Recommended Hardware

  • ProcessorA mid-range chip from the last 4-5 years is more than sufficient to handle real-time physics calculations.
  • Audio: Working speakers to hear the start and end measurement beeps, essential for operating without looking at the screen.
  • Battery: Intensive use of the sensors and the screen always on during measurement sessions can consume battery faster than normal.

The analysis software was developed using a Samsung Galaxy A56 smartphone for testing, the performance data of the tool refers to tests carried out with this device

Summary for the user:

If you have an iPhone (7 and later) or a mid/high-end Android device from the last 4 years, the app will run perfectly. The main limiting factor is usually the quality of the gyroscope: more expensive phones tend to have sensors with less electronic "noise," ensuring more stable and accurate swingweight measurements.
