Low glucose notifications notify you the moment your glucose drops below 70 mg/dl and is available to all Signos users. Real-time low notifications and the symptom logging prompt are automatically enabled for the Signos PCOS program only, but can be enabled for other users. Signos wants to help you connect the dots between your glucose and how you actually feel.
How Low Glucose Notifications Work
Signos sends a low-glucose notification when 3 consecutive readings fall below 70 mg/dL (~10 min apart). Your notifications appear as both push notifications and in-app banners.
What the notification includes:
- A push notification to your lock screen
- An in-app banner on the Home screen while the event is active
- A symptom logging prompt when you tap either one
Setting up Low Glucose Notifications
Low glucose notifications are on by default if you've indicated you have or suspect PCOS. If your PCOS program is off or you’ve identified as a male, they're off by default — but you can enable them anytime.
For PCOS/PMOS users:
Once you turn on your PCOS mode toggle and update your cycle preferences, you should see a pop-up that lets you decide whether to turn on or off your low glucose notifications.
You can change your cycle preferences and turn off the PCOS mode at any time, as well as disable features such as low glucose, without losing any previous data.
For Male users or non-PCOS users:
To turn low glucose notifications on or off:
- Open the Signos app
- Tap Accounts and Settings
-
Go to Notifications
- Find Low Glucose and toggle it on or off
When notifications are off, Signos still detects and records low glucose events in the background — you just won't be interrupted. You can still see your glucose data in the app at any time.
What to do if you get a Low Glucose Notification
- Tap the notification or in-app banner. This opens the symptom logging screen directly.
- Select any symptoms you're experiencing right now. Choose everything that applies, or "Nothing - no noticeable symptoms" if you feel fine. Both responses are useful data.
- Submit your log. It's automatically linked to this glucose event.
- You can choose to eat something to raise your glucose levels. Pairing carbs with protein or fat tends to produce a more stable recovery than carbs alone. You can select from the options on the screen, or choose “other” to go to the food database. You can also skip this step by selecting “Skip for now”.
The low glucose event will persist on your graph as a point of interest (POI) if you choose to skip logging.
| 💡 Log "Nothing". Feeling fine during a dip is data, not a reason to skip logging. It helps Signos understand what a glucose crash actually looks like for your body. |
What happens after a Low Glucose notification
- If you log a symptom during the low glucose event, once your glucose returns to your optimal range, you will receive a glucose recovery check-in.
- You will not receive a recovery check-in if you skip or select “nothing, no noticeable symptoms” during the initial low glucose alert.
What the Recovery notification includes:
- An in-app banner on the Home screen while the event is active
- A symptom logging prompt that includes a snapshot of your graph and information on how long your glucose dipped
The Glucose Recovery check-in lets you log any symptoms you feel and add personalized notes to the event, and it displays this information on your Home screen and Log page. If you choose to skip logging, no glucose recovery event appears on your graph.
Nighttime & Sleep Low Glucose Events:
Signos doesn't wake you up for low glucose. Notifications are suppressed by default between 11 pm and 6 am. Genuine overnight events are still recorded. When you open the app in the morning, any significant dips are tagged on your home screen, so you have the full picture without being woken up for it.
Signos also uses a compression-low classifier to filter out false readings caused by sleeping on your sensor arm — these show a sudden steep drop that recovers quickly on waking. They're flagged separately and don't trigger notifications.
What actually happens overnight:
- Low glucose events are still detected and recorded during sleep hours
-
Compression low patterns are flagged separately and excluded from notifications
- When you open the app in the morning, any genuine overnight events are shown on your home screen and in the log tab — so you have the full picture without being woken up for it
This means your overnight glucose data is never lost, just held until you're ready for it.
If you’re receiving incorrect low glucose notifications or something doesn’t look correct, reach out to Signos Customer Support at support@signos.com.
Troubleshooting
| WHAT'S HAPPENING | WHAT TO CHECK |
|---|---|
| Not getting push notifications | Go to your Accounts & Settings → Notifications → confirm notifications are enabled. Also, check that Do Not Disturb isn't blocking them. |
| Banner appears but tapping does nothing | Force-close the Signos app and reopen it. If the issue continues, check that you're on the latest app version or reach out to support@signos.com. |
| Notifications are waking me up at night | Nighttime suppression should be between 11 pm - 6 am, if you're receiving notifications, please check your notification settings and reach out to Signos Support. |
| I don't see low glucose notifications at all | Make sure you have low glucose notifications on. Go to Accounts and Settings -> Notifications, then toggle Low Glucose Notifications on to receive notifications. |
| Data gap during the notification window | Signos won't generate notifications during CGM data gaps. Make sure your biosensor is connected, and Bluetooth is on. |
| Frequent notifications but glucose seems fine | A steep, brief dip that resolves quickly — especially at night — may be a compression low from sensor pressure, not true low glucose. Contact support if this is happening regularly. |
Quick Tips
- Pair carbs with protein or fat after a dip. It helps your glucose recover steadily instead of swinging into another spike.
- Log every notification, even mild ones. The pattern over time matters more than any single event.
- Check your weekly insights to see how often dips occur and what might be driving them—meals, activity, cycle phase, or something else.
- Keep your biosensor connected. A loose sensor or dropped Bluetooth connection creates data gaps that prevent alert delivery.
- Notification thresholds are science-based and set by the Signos team. You can't adjust the threshold manually at this time.
| ⚠️ Not a medical device alert. Signos low glucose alerts are designed to support lifestyle awareness, not to diagnose or treat hypoglycemia. If you experience severe symptoms or are at risk for serious low glucose events, talk to your healthcare provider. |
