FAQ

  • I haven’t received a report, even though I ended my session.

    Report processing typically takes 20-30 minutes, but can take up to a few hours in some rare situations.

    First, confirm that the app indicates the session is done, or that the app is back in the home screen.

    Once you’ve confirmed that, allow for a few hours of wait time. Make sure to check both your phone notifications (if you’ve enabled them for the Wesper app) and your email for any messages from Wesper.

    You can also check for any new reports in the Reports page of your app.

    If the report is still missing, please contact Wesper Support at support@wesper.co.

  • I’m trying to start a session, and the LED at the center of the patch is not illuminating at all.

    First, find a well-lit area and confirm the LED is not illuminating. Sometimes the LED can be difficult to see through the fabric.

    If you’ve confirmed that, it’s likely your patch’s battery is depleted. Place it on the charger, confirm the blue charging LED at the corner of the patch is illuminated, and allow for a 3-hour charge cycle.

  • I’m trying to start a session, and the LED at the center of the patch is illuminating red, and the app cannot start the session.

    Make sure you’re pressing the button for at least 3 seconds. If you’ve done that, and the LED is still red, your patch is malfunctioning. Please contact Wesper Support at support@wesper.co

  • I’m trying to start a session, but the app will not connect to the patch.

    You can try the following things to try to resolve the issue:

    1. Make sure Bluetooth is enabled on your phone
    2. When pressing the patch buton, make sure you’ve held it down for at least 3 seconds
    3. Restart the app and try again
  • My app is stuck at the Uploading screen. What can I do?

    First, confirm that you have internet enabled on your phone.

    Once you’ve confirmed that, force quit and restart the app and check to see if progress has resumed. Allow for a few seconds for the progress bar to update.

    If that has not resolved the issue, contact Wesper Support at support@wesper.co

     

  • My app is stuck in the Reading Patches screen. What can I do?

    There are a few things you can try to resolve the issue:

    1. Bring the patches close to the phone.
    2. Place the patches on the charger, and briefly press the button on each patch.
    3. Force quit and restart the app

    If while attempting the above you see that one of the patches’ LED is blinking green, allow a few minutes to see if the progress bar moves beyond 50%. If the app is still stuck, contact Wesper Support at support@wesper.co.

  • Will the patches run out of battery in the middle of the night?

    No, if the app has not notified you of a low-battery, the patches will work continuously for at least 12 hours.

  • The patches have been charging for a very long time, and the charging LED is still illuminated. Are they charged?

    Check that the charger is plugged into the wall and not into another electronic device such as a laptop. If the charger is connected to the wall, and the patches have been on the charger for at least 3 hours with the LED illuminated, they are fully charged.

  • The corner charging LED is flickering blue when the patches are being charged.

    Gently move the patch around a bit to ensure it’s well-seated in the charger bays. If that doesn’t resolve the issue, remove any adhesive strips still on the patch, and make sure there’s no debris or anything else under the patch while it’s on the charger.

  • No LEDs are illuminated when the patch is placed on the charger

    Check that the charger is plugged into the wall and not into another electronic device such as a laptop. If you have the charger plugged into a wall outlet, try moving the patch around a bit, to be sure it’s well-seated in the charger.

  • How can I tell if the patches are charged before I go to sleep?

    When placed on the charger, the patches will illuminate a blue LED, situated at the corner of the patch. The patches typically are fully charged within 3 hours, so if they’ve been on the charger for that period of time with the LED illuminated, they are fully charged.

    In addition, the app has a built-in low-battery detector which will prevent you from testing if either patch isn’t charged enough for an overnight session. 

  • Can the patches keep working while they’re on the charger?

    Yes, the patches can maintain a connection with the app while on the charger, for example, while recovering the night’s recordings.

  • The patch’s center LED is blinking green. What does that mean?

    This can mean one of the following two, depending on your current session state:

    1. If you’re in the process of setting up a new session, it means the patch is connected to the app, and is waiting for the session to start, after which the LED will shut off.
    2. If you’re in the process of finishing a session, it means the app is currently recovering any remainder of the recording not read during the night, after which the LED will shut off.

    If you see blinking green light outside of those two instances, it may be due to a malfunction. Please contact Wesper Support at support@wesper.co.

  • The patch’s center LED is blinking blue. What does that mean?

    It means that the patch is searching for a connection. Once you’ve begun setting up for a session in the app, it will establish a connection, and it will switch to blinking green.

    If the patch is blinking blue during the session, that may be due to a malfunction. Please contact Wesper Support at support@wesper.co.

  • The patch’s center LED illuminates in red when I press the button. Is the patch malfunctioning?

    If the button-press is short (under 3 seconds), then the patch is working as expected.

    If the button-press is long (over 3 seconds), for example when connecting the patch to the app at the start of a session, and the LED remains red, the patch is malfunctioning. Please contact Wesper Support at support@wesper.co.

  • Wesper is showing me sleeping positions I’m certain are incorrect. Why is that?

    Typically, there are two reasons for why this may be happening:

    1. There were no upright positions – Wesper requires 30 seconds of upright time to calibrate its position calculation algorithm. This can be accomplished by standing or sitting for 30 seconds before or after your session.
    2. There might have been patch positioning issues – for your next session, try to keep the stomach patch as close to the center of your stomach as you can, as this helps Wesper calibrate its position algorithm.

    There may be other factors which can confound the position algorithm, such as: a non-traditional sleeping posture, such as semi-reclined, or performing physical activity while wearing the patches.

  • How does Wesper calculate Sleep Efficiency?

    Sleep Efficiency is calculated using Total Sleep Time (adding up all the periods of sleep throughout your session) then dividing that time by the length of the whole session to produce a percentage.

  • How does Wesper calculate Total Sleep Time?

    Wesper Light’s algorithms use breathing, heart rate and motion patterns to detect if you’re asleep. Total Sleep Time is a sum of all of the times throughout your session when you were asleep.

  • Wesper said I was awake at a certain time, but I don’t recall being awake then. Is there an issue with my device?

    No, Wesper Light’s algorithms use breathing, heart rate, and motion patterns to detect your sleep state. During the night, you may experience short sleep disturbances that cause brief wakefulness, but may not register in the morning. Wesper’s algorithms can detect those, along with longer wakefulness episodes, such as getting up to go to the bathroom, etc.

  • What kind of sleep state can Wesper detect?

    Wesper Light can detect 4 sleep states – Wake, Light, Deep, and REM. Wesper uses your breathing, heart rate, and movement patterns to tell if you’re awake or asleep, as well as which sleep states you were in during the night.

  • My spouse/partner snores. Will Wesper detect their snoring as mine?

    Sometimes, especially if your mobile device is close to your partner. You can mitigate this issue by attempting to bring the mobile device further away from your partner, while still keeping it close to you.

  • I have a white noise machine. Will Wesper still detect my snoring?

    Yes, Wesper’s algorithms filter out noise machines.

  • I live in a noisy area. Will Wesper still detect my snoring?

    Yes, Wesper’s algorithms filter out background noise.

  • I know I snore, and Wesper detected 0 minutes of snoring. Why is that?

    The most common reasons for under-detection of snoring are a) the phone not being close enough to you while you sleep, b) a periodic electrical or mechanical noise, such as a CPAP machine or oscillating fan. For best results, try to keep your phone away from any machines or appliances that can produce these specific types of noises.

  • How does Wesper detect snoring?

    Wesper uses the microphone in your mobile device to record audio with your permission. The audio is then processed by Wesper’s algorithms to pick out periods of snoring. For best results, try to keep the mobile device as close to you as you can, for example on a nightstand or on the floor next to the bed.

  • My SpO2 sensor said I had no oxygen drops, but Wesper detected inconsistent breathing events. How is that possible?

    Wesper Light’s algorithms detect drops in breathing volume. These abnormal breathing events are a precursor to a reduction in oxygen entering the lungs and do not automatically correspond with a decline in blood oxygen levels, especially in individuals with milder sleep problems.

  • Can Wesper measure SpO2 (Oxygen Saturation)?

    No.

  • Does Wesper detect apneas or hypopneas?

    No, Wesper Light is not a medical device and cannot detect apneas or hypopneas. Wesper Light detects inconsistent breathing, which is designed to be more sensitive, as it’s intentionally tuned to pick up even small drops in breathing volume.

  • What kind of breathing information does Wesper collect?

    Wesper Light uses clinically-validated respiratory measurements to identify periods of inconsistent breathing throughout the night. If your breathing volume decreases frequently or lasts for long periods of time, you’re more likely to have restless, lighter sleep, and experience increased daytime sleepiness, dizziness, headaches, and overall reduction in quality of life.

  • What kind of insights can I expect to get from Wesper?

    Wesper Light can generate accurate insights about the quality of your breathing, amount of time snoring, sleeping positions, heart rate, sleep time, sleep efficiency, and sleep staging (wake / light / deep / REM). It also provides other environmental measurements, such as patch temperature and ambient noise.

    These insights are provided for each night test and as trends over time.

  • How close does the phone have to be to the patches while I sleep?

     Ideally within 4 feet. Try to avoid placing the phone near metallic objects, such as watches or other electronic devices.

  • How long does it take the data to be uploaded in the morning?

    It depends. Typically it’s between 1-5 minutes, but in some rare situations, it may be as long as over an hour.

    The Wesper patches record and store all of their data, and then send it to the Wesper app over Bluetooth. That connection may experience normal interruptions, which would then require the app to recover any remaining recording data in the morning. The time required for the app to complete the recovery depends on the volume of connection interruption throughout the night.

    Some tips for reducing the potential for disconnections: keep your phone within 4 feet of the patches overnight, and avoid placing any large metal objects or electronics next to the phone.

  • Can I shut off the app overnight?

    Yes, but it’s not recommended. Shutting off the app prevents it from obtaining the recordings overnight, requiring the app to recover them in the morning.

    This morning-only recovery may take up to 2 hours, during which time the phone will have to be adjacent to the patches.

    Additionally, shutting off the app prevents it from recording audio overnight for snoring detection.

  • Can I turn off Bluetooth overnight?

    Yes, but it’s not recommended. Disabling Bluetooth prevents the app from obtaining the recordings overnight, requiring it to recover them in the morning.

    This morning-only recovery may take up to 2 hours, during which time the phone will have to be adjacent to the patches.

  • Can I use airplane mode overnight?

    Yes, but it’s not recommended. Airplane mode disables internet and Bluetooth, preventing the app from obtaining the recordings overnight, requiring it to recover them in the morning.

    This morning-only recovery may take up to 2 hours, during which time the phone will have to be adjacent to the patches.

  • If I need more adhesive strips, how can I get them?
