It works the same as the Alert Stresslocator Oximeter when using the Sleep as Android app with this device!

Digital wrist pulse oximeter is more comfortable and more precise than any finger oximeter. The instrument measures oxygen saturation SPO2, pulse rate, and pulse intensity PR; these physiological signals of the person being monitored include oxygen volume waves and are transmitted to a smartphone or a tablet with Android via Bluetooth. It has a minimalist and exquisite design, comfortable to be worn on the wrist. Pulse waveform and numerical value can be displayed on the OLED display.

Nighttime measurements with Sleep as Android app

The device can be used for many purposes, but it is to underline that thanks to its comfortability, this is one of the few oximeters suitable for long measurements, even those of whole sleep time. The advantages are obvious; for example, it allows you to pre-estimate your chances of suffering from sleep apnea, a potentially hazardous sleep disorder characterized by breathing irregularity. Furthermore, the digital wrist pulse oximeter is designed to work with the Sleep as Android app, processing data of breathing sent by the oximeter during the night and providing very reliable results. Thanks to this combination, you can reveal the risk of suffering from sleep apnea and prevent it from having serious consequences for you by visiting your doctor in time.

Sleep as Android

The Android application StressLocator

NEW - compatible with project HRV Mind Machine

The StressLocator, which has been developed for almost one year, consists of three main parts: a sensor, which measures pulse waves, a client application for Android, and a server application. These three components allow you to measure mental and physical stress and quickly estimate your current condition. Measurement can be done anywhere where you have your mobile phone with an installed client application. The sensor ensures precise measurement and comfort. The results can be used to plan your activities and thus utilize your potential.

The application with its results is based on a wide range of graphs, precisely calculating your condition. The weakest point is the sensor with which you measure. We strongly recommend purchasing our Bluetooth oximeter sensor. Interpretation of data is based on deep research, study, and analysis of known work in this field.

Apart from that, the application offers breathing exercises to improve and train your concentration or relaxation quickly, and new exercises allow you to try classical meditation.

The iPhone Application is slightly different and doesn't contain all the functions, for example, Save Astronauts game and Meditation exercise.

Fun with your results

We thought it would be fun to anonymously share our results and see where are the lowest or highest levels of stress. You can compare it worldwide, but also zoom to cities. We are so curious to see the results and find out which is the best place to live. We hope you are too! Check our maps.

Are you competitive? You can easily get to the world top10! :) Try breathing exercises, improve your mental condition, and score in relaxation or concentration competition. You can repeat the training as many times as you need. You can see the world top10 in your application under the button "Contest." Good luck!

Since November 2014, there's a new challenge for competitive persons: Save Astronauts game, now integrated into the StressLocator app! It's designed especially for Oximeter and controlled only by your will. Are you able to concentrate quickly? Good, then you have a chance to rule the tables! Concentrate as quickly as you can to save the astronauts and achieve the best results. Have fun!
