Using Lumo Back

What functionality does Lumo Back have?

Lumo Back does the following:

  1. It measures your lower back posture, and vibrates when you are not in good posture
  2. It tracks your movements, i.e. when you are sitting, standing, walking, and running. It even tracks your sleeping positions.
  3. It counts your steps.
  4. It displays hourly/daily/weekly/monthly statistics about your movement and posture data.

How do I get started?

  1. Once you have purchased and received your sensor, plug it into a power source to wake it up.
  2. Be sure you have a compatible device. Lumo Back is currently compatible with the following iOS hardware: iPhone 4S or later, iPad Air and iPad Mini.
  3. Apple users: Download the Lumo Back App from iOS here: You can also find this by going to the Apple App Store and searching for “Lumo Back.”
  4. Open the Lumo Back App and follow the instructions. The app will take you through a short series of movements to do the initial calibration (e.g. walking, sitting, slouching, etc.). This setup takes about 5 minutes. Through this process you will begin to get to know Lumo Back and what it can do.

How do I re-calibrate the Lumo Back?

You can re-calibrate the sensor at anytime directly from the app by using the press & hold to CALIBRATION function.

To re-calibrate the sensor:

  • Click on the press & hold CALIBRATION function from the app.
  • Make sure Lumo is matching your sitting or standing position.
  • Rotate your pelvis forward and lift your chest.
  • Tap the blue “Calibrate” pop up via the app and follow the instructions. The sensor will give 5 more quick buzzes to signal calibration is complete.

The data gained from re-calibration is used by the sensor to mark what is a good, neutral sitting or standing position for the individual wearing it.

How do I turn my Lumo Back sensor On and Off?

The black, dime-sized, indented circular button on the face of the sensor acts as a capacitive touch button that can touched to manually turn on and off the sensor.

The sensor must be held horizontally (so if you are looking at the sensor it should be wide, flat, and showing the logo facing up) in order for the button to turn the sensor on or off. This condition is a preventative measure so the sensor is not accidentally turned off or on when the user leans up against something soft, such as a couch or car seat that could potentially press the button.

You can turn the sensor ON by holding the on/off button for at least 1-2 secs until the LED light on the bottom of the sensor (next to the USB port) flashes green and sensor vibrates once.

You can turn the sensor OFF by holding the on/off button for at least 1-2 secs until the LED light flashes red and the sensor vibrates twice.

You can determine if the sensor is currently on by tapping the on/off button and seeing if the LED flashes green.

How is Lumo Lift different from Lumo Back?

Lumo Lift is a small sensor that you can clip anywhere on your chest and shoulders using an interchangeable magnetic clasp. It focuses on improving how you hold your chest, shoulders, and upper back in order to help you gain confidence, improve your appearance, and lead a healthier, more active life. Throughout the day, Lift tracks how long you spend in strong, confident posture, as well as how many steps you take and how many calories you burn. When you want to buckle down and really focus on improving your posture and presence, enter a Coaching session to receive gentle vibrations when you slouch. Based on your profile and behavior, Lift provides insights and actionable recommendations to help you improve. You’ll also earn badges and awards for being awesome!

Lumo Back is worn on a belt around your lower back and focuses on improving lower back posture to prevent and reduce back pain. It vibrates when you slouch to remind you to sit straight and stand tall. Lumo Back is great at encouraging you to move more throughout your day by tracking the amount of time you spend sitting and standing. It also tracks the number of steps you take, the distance you walk and run, and the calories you burn each day.

What are the different types of buzzes and what do they mean?

Lumo Lift provides vibrations under the following circumstances:

  • 1 buzz indicates that you have turned Coach Vibrations on.
  • 1 long buzz indicates that you are in poor posture when Coach Vibrations is turned on.
  • 2 buzzes indicate that you have turned Coach Vibration off.
  • 3 buzzes indicate that you have Aligned your Lumo Lift sensor.

If you feel like you are receiving vibrations when your posture is good, please Align your sensor by getting into your best posture and double-pressing on the sensor button. This allows your Lumo Lift to understand what your good posture looks like so that it can accurately monitor your posture throughout the day.

How do I customize the settings?

From the Lumo Back App go to Settings > Advanced Vibration Controls. There are 3 settings you can customize to your liking:

  • Bad Posture Threshold
  • Vibration Delay
  • Vibration Intensity

How much data can the sensor store and how often do I need to check in with the app?

The sensor can store up to about 1 month’s worth of data. You can check in with the app as frequently as you like.

What’s the difference between Lumo Lift and Lumo Back?

Both devices are designed to help you improve your posture and sit and stand taller every day. The difference is in the device itself and what type of posture it focuses on. The Lumo Lift is a small, discreet sensor that attaches to your clothing like a lapel pin by a magnetic clasp. It is affixed under your collarbone on your shirt or undergarments to detect posture and coach you to sit and stand taller. The Lumo Lift focuses on improving upper back posture and how you hold your chest and shoulders.

The Lumo Back is our first generation posture coaching device and is worn as a belt around your lower back. It best detects lower back posture and to prevent and reduce back pain.

Where should the Lumo Back sensor lie on my back?

The Lumo Back sensor is lightweight and held in place with a thin band and is worn discreetly around your waist or lower back. The Lumo Back sensor should sit just above your hip bones for best accuracy, with the sensor portion sitting on your back. To keep it in place, make sure the strap is snug, but not tight.

Is Lumo Back better at detecting lower back slouching than upper back?

Yes. Lumo Back is highly sensitive at measuring lower back spinal posture. In most cases, poor lower back posture leads to poor neck and upper back posture. By correcting lower back posture, Lumo Back will help correct total back posture. With a single sensor solution, Lumo Back addresses many but not all cases of poor spinal posture.

What happens in the Connect & Calibrate tab?

The Connect & Calibrate section allows you to connect and reconnect to your sensor. This section also allows you to calibrate your sensor to your body and behaviors.

Connect to a Sensor

  • When the sensor is on it will be listed under the “Connect a Sensor“ page. To connect to your sensor you should tap on the listed sensor (the sensor must be on to be listed). This will direct you to a page with a green “Connect“ button that you should tap in order to connect to that sensor. The LED light on the bottom of the sensor will turn blue when the sensor is connecting to the App. Your sensor listing will have a checkmark next to it if the sensor is on and currently connected to the App. If you want to disconnect from your sensor you can tap the sensor listing that has a check next to it and then tap the red “Disconnect“ button.


  • In the calibrate tab you can re-calibrate and reorient LUMO.
  • Calibrate – If you feel that the Lumo avatar is inaccurately reporting your posture you can reset your “Good Sitting Position“ and “Good Standing Position“. To reset your sitting position you should tap the button “Reset Good Sitting Position“ and then follow the instructions by sitting as straight as possible while the progress bar loads and the sensor collects the information. To reset your standing position you should tap the button “Reset Good Standing Position“ and then follow the instructions by standing as straight as possible while the progress bar loads and the sensor collects the information. The data gained from the re-calibrating exercises are used by the sensor to mark what are good, neutral sitting and standing positions for you.
  • Reorient – when you reorient your sensor you are asked to walk until a progress bar loads and to sit and lounge in a chair while a progress bar loads. The information gained from the walking and lounging exercises are used by the sensor to set the parameters for your body. The parameters are then used to tell when you are slouching and when you are practicing good posture.


  • On the Reset page you can reset your password, sensor, and erase all the data from your sensor. On the Password tab you can easily change your password (if you know your current password) or you can reset your password by having a new password emailed to you. On the Reset Sensor tab you can reboot the sensor by simply tapping Reset Sensor and it reboots the sensor by simply turning it off and on. On the Erase All Data from Sensor tab you can erase all of the data from the sensor and effectively restore it to factory settings by tapping the “Erase All Data From Sensor“ button. Erasing all data from the sensor clears the sensor back to a neutral state and disconnects the sensor from your account. Erasing all data from a sensor is a way in which you can transfer ownership of sensor belts. If you want to give your sensor to a different person, you can erase all the data from the sensor and it is as good as new for someone else to use.

Recover Data

  • By pressing the “Recover Month of Data“ button you can access your previous months worth of data. You can only recover the previous month of data if you were wearing the sensor and has data from that month.
