GluKaMon: The Free CGM Companion for Your Bike

Whether you are a recreational rider and don’t want to “bonk,” a competitive cyclist optimizing your performance, or a parent who wants to monitor your child’s glucose on a family ride, GluKaMon is the ideal companion to your (or your child’s) Continuous Glucose Monitor (CGM). GluKaMon doesn’t replace the CGM app on your phone, it is a companion app (a secondary display) for your bike computer, so you can monitor your glucose easily while riding

Start now

Monitor Your Glucose While You Ride

GluKaMon turns your Hammerhead Karoo into a CGM companion. Built by cyclists with diabetes for cyclists with diabetes, GluKaMon gets data from your CGM and displays it on your Karoo. GluKaMon can also record your readings to a FIT file for analysis

And it’s free!

Why GluKaMon

Monitor your glucose on your bike computer, so you can focus on your ride

A wide choice of customizable data fields to track what you want to see, how you want to see it

Your choice of mg/dL or mmol/L, glucose zone ranges, 3-color mode for simplicity or full color for more nuance, with 3 different graph scales

GluKaMon is easy to use: A single app that you install on your Karoo and starts automatically when you start your ride

GluKaMon speaks every language supported on the Karoo: English, German, Spanish, French, Italian, Portuguese, Simplified Chinese, Traditional Chinese, Korean, and Japanese

Visual and audio notifications to let you know when your glucose changes, without having to check your phone

Designed for your Hammerhead Karoo. GluKaMon follows your standard Karoo settings for field alignment, light and dark modes

You can optionally record your glucose to a standard FIT file, along with other ride and sensor data (e.g. cadence, speed, heart rate monitors, power meters, body temperature/sweat sensors, etc.) to analyze your ride

GluKaMon supports your Continuous Glucose Monitor: GluKaMon connects directly to Dexcom and Freestyle Libre servers, and through Nightscout, Gluroo, xDrip, and Juggluco to all major CGM providers

What You Need to Use GluKaMon

Compatibility

GluKaMon runs on the Hammerhead Karoo (Karoo 2 and New Karoo / Karoo 3)

GluKaMon supports Dexcom Continuous Glucose Monitors (G6 and G7) directly, by connecting through the Dexcom Share API

GluKaMon supports Freestyle Libre Continuous Glucose Monitors (Libre 2 and Libre 3) directly, by connecting through the LibreLinkUp API

GluKaMon also supports Nightscout, including Nightscout compatible services like Gluroo, so any Continuous Glucose Monitor that delivers data into Nightscout (or Gluroo) can be monitored using GluKaMon. This includes:

  • Dexcom G4 Platinum (via Share + receiver bridge)
  • Dexcom G5 Mobile
  • Dexcom G6
  • Dexcom G7
  • FreeStyle Libre
  • FreeStyle Libre 2
  • FreeStyle Libre 3
  • Medtronic Enlite
  • Medtronic Guardian Sensor 3
  • Medtronic Guardian Sensor 4
  • And any other CGM that integrates with Nightscout (see https://nightscout.github.io/uploader/uploaders/ for details)

GluKaMon supports Juggluco and xDrip as well, which support multiple CGMs and which allow you to use GluKaMon anywhere you ride, even outside of cellular coverage

GluKaMon optionally records to the standard FIT file so applications like intervals.icu can include it in post-ride analysis

Requirements

  • GluKaMon requires a network connection, either using the integrated cellular connection on the Karoo 2 (which requires a SIM card and cellular data service), WiFi, or tethering via Bluetooth to your phone
  • If you use Juggluco or xDrip on your phone, you can use GluKaMon even where there is no cellular coverage, by connecting to Juggluco or xDrip using a wifi hotspot on your phone
  • Your Karoo should have the clock set to “automatic” so it will be accurate and in synch with the CGM clock. GluKaMon compares the time your CGM recorded a glucose reading to the time on the Karoo to determine if data is stale, so it is important that the clock on your Karoo is correct
  • Be careful about the number of bluetooth connections on your phone. Some phones can’t manage many bluetooth connections, so if your phone is connected by bluetooth to headphones AND your Karoo, it may not be able to connect to your CGM sensor at the same time
