About this app

The Biologix Sleep Study® is simple, accessible, and can be performed at home. At bedtime, simply place the Oxistar sensor on your finger and start the test using the Biologix app. Upon waking, the report is available in seconds, with data that assists in sleep analysis.

Our solution features:

Important:
The test can only be performed with the Oxistar sensor, available at Biologix accredited centers.

This is a tool to support sleep analysis and does not replace evaluation, diagnosis, or treatment performed by healthcare professionals.

Há algum problema para acionar o teclado do smartphone nas áreas onde se digita. A área de tela do teclado "vai subindo" lentamente.
