How do I log a meal in Gluroo?

There are always at least 2 ways to log your diabetes data in Gluroo. 

  • You can simply type your data in (eg: “Sandwich 50g”)
  • You can also log using the Plus Menu
    • Then select what you would like to log (eg: Meal > enter Pizza as a description, 50g as an amount):

How do I connect my CGM? (Dexcom, Libre)
  1. Tap the “options” button in the top right of the app (three vertical dots)
  2. Tap “CGM”
  3. Select your CGM from the list – Dexcom, Freestyle Libre, Other, or BG Meter.
  4. (For Dexcom CGMs, enter your Dexcom Share username and password. For Libre CGMs, enter your LibreLinkUp username and password.)
  5. Tap login
  6. Your CGM data will now be available in Gluroo for everyone in your GluCrew to see!
How do I invite a member to my GluCrew?
  1. Tap the “options” button in the top right of the app (three vertical dots)
  2. Tap “GluCrew”
  3. Tap “Invite new Crew member”
  4. Enter the email of the person you want to invite, or generate a QR code for them to scan (note that they need to install Gluroo on their phone first!)
How do I edit an entry?
  1. Long-press on the entry
  2. Tap “Edit”
  3. Update the entry!
How do I delete an entry?
  1. Long-press on the entry
  2. Tap “Remove”
  3. The entry will be lined out for a few seconds before being permanently removed from the GEL. This gives you the chance to un-remove it if it was an accident by long-pressing again.
How do I set the time of an entry?

With Gluroo’s Natural Language Processing (NLP) capabilities, you can simply type your message and Gluroo will understand it.

For example, if you want to log that you dosed 5 units of insulin 30 minutes ago, you can type “Dosed 5u 30m ago.”

Note that Gluroo will understand, for example, “1.5h ago” or “90m ago” but not “1 hour and 30 minutes ago”.

See What Texts Gluroo Understands for more information.

How do I change the time of an entry?
  1. Long-press on the entry
  2. Tap “Set Time”


  1. Swipe left or right on the entry to move it forward or backward in 5 minute intervals
How do I set a meal reminder for the future?
  1. Tap “+”
  2. Tap “Meal”
  3. Set the time in the top right as either “now”, “+15m”, or set a specific time by tapping the clock icon!

Alternatively, use Gluroo’s text processing capabilities! For example, try typing:

  • “40g toast in 15(m | min | mins | minutes)”
How do I enter finger prick readings?
  1. Tap “+”
  2. Select “Blood Glucose”


  1. Type “Fp 115”. Gluroo will automatically interpret this as a 115 mg/dL fingerprick reading.
How do I change blood sugar units? (mg/dL vs. mmol/L)
  1. Tap the Options button (three vertical dots)
  2. Tap “GluCrew”
  3. Under “GluCrew Settings”, select the Blood Glucose Units that you want to use.
What is the red dot next to the PWD profile picture?

The red dot in the PWD profile picture indicates that one or more of the PWD’s devices are expired or expiring soon. Things like insulin vials, pens, CGM sensors, CGM transmitters, and pump devices can be tracked. Gluroo can remind you to replace them when the time is near!

Why does my blood glucose level (BGL) have a line through it?

A line through the BGL indicates that the most recent CGM reading is more than 9 minutes old. This means that the reading may be old and/or inaccurate.

How can log a “new” transmitter that I put on many days ago?
  • long-press the 1h button to go back one day at a time
  • Or, type “new transmitter on…”

Diabetes Education Questions

What’s a Carb Ratio (CR)?

The insulin-to-carb ratio, or carb ratio, is the number of grams of carbohydrate that one unit of rapid-acting insulin will cover.

Your healthcare team should help you calculate this number. Only use the number provided by a doctor.

What is an Insulin Sensitivity Factor (ISF)?

The Insulin Sensitivity Factor is the estimated drop in blood sugar for a correction dose of 1 unit of insulin.

Your healthcare team should help you calculate this number. Only use the number provided by a doctor.

What are Basal and Bolus insulin?

Bolus insulin is fast-acting (or “rapid-acting”) insulin – the kind that you inject for meals or to correct a high. Basal insulin is slow-acting and helps keep your blood sugars steady throughout the day.

What is the GMI statistic?

GMI stands for Glucose Management Indicator. It’s often used as an estimate of your HbA1C that is arrived at by analyzing your CGM readings over time, whereas the HbA1C is derived in a lab by analyzing your blood itself. HbA1C is more accurate, but GMI can be a handy tool to see how you’re doing in between visits with your endocrinologist.

Data Questions

How do I disable battery optimization on Android?

Gluroo works best with battery optimization disabled (especially for the OP5 integration to work, and especially on the PWD’s (person with diabetes) phone). This page has information about how to disable battery optimization on Android phones such as the Google Pixel, Samsung, LG, OnePlus, and more. You can see a more general writeup of the process on our post that discusses how to remotely view data from the OP5 using Gluroo.

Can I generate reports about my blood glucose data?

Coming soon! Gluroo users will have access to a wide array of charts and analytics that they can use to garner insights about their diabetes control.

My child is 8 years old and has T1D. Can they use Gluroo?

Yes, provided that an adult parent or guardian is providing permission and active supervision. Gluroo is COPPA compliant and users must agree to the Gluroo privacy policy to use the app.

How do I delete my account and data?

Please send an email to help@gluroo.com with your email, contact information, and your request for deletion. After we confirm your request, we’ll delete your account and all of your data irrevocably.


I accidentally selected that I was not the person with diabetes (PWD) when setting up my account. How can I set myself as the PWD after the fact?

If you accidentally chose the wrong option (e.g. setting up the app for a young child), you can select which person in your GluCrew is the PWD after the fact.

To do this, you must first add another member to the GluCrew, by inviting yourself or whoever else. Once there are at least 2 members in the GluCrew, you can then navigate to the GluCrew settings page and tap the other member to set them as the PWD.

Note that you cannot set yourself as the PWD from this page, so you may need to do it from the other persons device, if you are the intended PWD.

Red reminder (low or high BGL alert) won’t disappear.

This is a known bug where even if you force-cancel a reminder, it will remain in place and is not able to be interacted with. While we’re working on a real fix, try signing out of the app, and then sign back in.

BGL data is not refreshing or is not up to date.

This is a known issue. While we’re working on a fix, you should be able to resolve it by signing out of the app, and then signing back in. If that doesn’t work, try following the these steps:

You should always use the PWD’s primary phone that is bluetooth-connected to the CGM for dosing decisions.  Is that up to date?  If not, follow Dexcom’s troubleshooting steps.

If the bluetooth-connected device is providing new values, is Dexcom Follow that is running on the same device as Gluroo also getting those new CGM values? If not, you probably have a network connectivity problem on either the PWD’s primary device where it is not able to upload the new values or on the device running Follow and Gluroo where they are not able to download those new values.  Double-check your Internet connection, and see if Dexcom has a known cloud outage or it is down even if Dexcom isn’t aware of it.

If Dexcom Follow is showing new CGM values on the same device or phone that Gluroo is running on and Gluroo is not showing those new CGM values, you can try closing Gluroo and re-opening it (iOS instructions, Android instructions).  If you still don’t see new values, please let us know.  You may be able to fix it on your own by going to

Menu ⋮ > Connections > CGM > Dexcom Share 

and tapping “Remove Dexcom connection” and then tapping that button “Login to Dexcom” again.  That should restart the server-side Dexcom follower fetcher, though you may have to wait for a new reading before your device will get a new value.

I want to change my Apple SSO share-email-address-with-Gluroo setting:

As a workaround for your iPhone right now, you can go to Settings -> your Apple ID profile (at the top) -> Password&Security -> Apps Using Apple ID -> Gluroo -> Stop Using Apple ID

And you’ll be prompted next time.

How do I use the DIY Loop (experimental) integration?

1. Tap the button to connect

2. Copy the username and password that was generated into the form under Settings > Services > Nightscout inside of the DIY Loop app. Be sure you don’t receive any errors after saving the connection.

I use a Do-It-Yourself system such as DIY Loop / AndroidAPS / etc. Can I use Gluroo?

Yes. As long as the system you are using allows you to connect to a Nightscout instance, you can use Gluroo. 

  • Just open Gluroo, go to the menu > Connections > Insulin 
  • Tap Connect DIY System
  • Copy the Nightscout URL
  • Paste this URL into the Site URL field in your DIY system
  • Copy the API Secret from the same location in Gluroo
  • Paste it into the field in your DIY System
  • Save the settings in your DIY system, and data will begin syncing to Gluroo soon after

What if I want to use Nightscout and Gluroo?

Once data from your DIY system is flowing to Gluroo, you can then forward all of Gluroo’s updates to your Nightscout URL.

Note: this requires advanced configuration in Nightscout. See here for more detailed instructions.
