SP Sensor - Monitor the angle!

Feature
- "SP Sensor" allows you to easily remotely monitor the status of an object using two Android smartphones, based on the "rotation angle" of the smartphone.
- Simply install "SP Sensor" on both the sensor and monitoring side smartphones, and link the smartphones using a QR code to complete the setup.
- Even if the monitoring side smartphone is connected to your home Wi-Fi, you don't need to open any ports! You can monitor the "rotation angle" of the smartphone even when you're away from home.
- Attach the smartphone with the sensor in the location where you want to monitor the rotation angle, and select "Run in the foreground" for the app.
- The monitoring side app displays the rotation angle status of the sensor side smartphone in real time.
- You can also set a threshold for the rotation angle you want to be alerted about in the sensor side app, which will then send notifications for when that occurs or is restored.
- Rotation angle data between devices is encrypted End-to-End using our proprietary P2P technology, so the contents cannot be seen by us or a third party. Also, communication data is not saved on the Cloud.
- Registration of user information to use the service is not required, and personal information is not acquired with this app.
- There is no charge for using this service.

Terms of use
- To use the service, you need to agree to the terms of service.
- There are advertisements displayed within the app.
