Your glucose,
big on your TV
GlucoTV shows your latest CGM reading on your Roku: a big number, trend arrow and chart, colored by your target range, with optional alerts. Works with Dexcom Share and Nightscout.
- 1
The reading
Big enough to read from the sofa, and colored by your range:
in range high or low urgent
- 2
Trend arrow
Which way it's heading, with two arrows when it's moving fast.
- 3
Change and age
How much it moved since the last reading, and how long ago that arrived.
- 4
Chart
One dot per reading over your target band, from 3 to 24 hours.
Three hours or the whole day
Left and Right on the remote switch between 3, 6, 12 and 24 hours. The chart sums up each range for you: time in range, the highest and the lowest. With Dexcom Share, the 3-hour chart is there from the start and the longer ones fill in over your first day, as GlucoTV collects your readings. With Nightscout, every range shows straight away.
Alerts you can see across the room
Switch them on at glucotv.com/account. While GlucoTV is on screen, a banner names the alert and the TV beeps when it starts, then again with each new reading while it lasts. The banner takes the reading's color, and it clears as soon as the reading is back inside the line. Urgent low, low, high and urgent high each switch on or off on their own.
Colorblind-friendly colors
Red, amber and teal can be hard to tell apart. Choose Colorblind-friendly for a TV on your account page and lows show in blue, highs in orange and readings in range in gray, darker when urgent. Every reading also says IN RANGE, LOW or HIGH under the number, so color is never the only clue. The GlucoTV Screensaver and that TV's viewer links follow the same choice.
Leave it on all night
To keep alerts sounding overnight, turn off your Roku's screensaver: Settings > Theme > Screensaver start time. After 10 minutes without a button press, GlucoTV switches to this dim view, which drifts slowly around the screen to help protect your TV from burn-in.
- Any button brings back the full screen, and so does an alert.
- Press * on the remote and choose Screensaver & Alerts to see both choices on the TV.
- Keep your CGM's own alarms switched on.
Set it once at glucotv.com
Your target range, urgent limits, units, colors and alerts live on your account page, the same settings your web viewer link uses. Change them there and the TV catches up within about a minute.
- mg/dL or mmol/L, always with one decimal in mmol/L.
- Standard or colorblind-friendly colors.
- Press * on the remote to see this TV's settings and the Screensaver & Alerts help, or to pair it again.
- When a reading is 10 minutes overdue its age turns amber, and red after 30, so an old number never looks current.
When the TV goes idle, your glucose stays
The GlucoTV Screensaver swaps Roku's idle screen for your latest reading, trend arrow, change and how long ago it arrived, updated every minute, with the reading in words. Pick one of four styles.
Alerts on the screensaver
Switch alerts on at glucotv.com/account and the screensaver shows a banner in the reading's color, in every style: amber for low or high and red for urgent, or blue and orange with colorblind-friendly colors. A screensaver can't play sound, so for a beep keep GlucoTV on screen.

Questions about the TV apps
Does GlucoTV update itself on my Roku?
Yes. Roku installs updates to its apps automatically, so new features reach your TV without you doing anything.
Do alerts work when GlucoTV isn't open?
No. The TV can only alert while GlucoTV is open and on screen, and the TV is on. GlucoTV is an extra screen, not a replacement for your CGM's own alarms, so keep those switched on.
Do TV alerts work while the Roku screensaver is on?
No. When your Roku's screensaver comes on, including the GlucoTV Screensaver, it covers GlucoTV and its alerts go quiet until you press a button. It's your choice:
- Keep the screensaver. It protects your TV from burn-in, and the GlucoTV Screensaver keeps your reading on screen. Rely on your phone or CGM for alarms.
- Turn it off, or make it wait longer, to keep GlucoTV and its alerts on screen: on your Roku, go to Settings > Theme > Screensaver start time. A picture left on for hours can burn in on some TVs, especially OLED ones, so after 10 minutes without a button press GlucoTV dims and drifts by itself.
Does the screensaver make sounds?
No. It shows your reading in your range colors, with a banner when an alert is on, but stays silent, and while it's on, GlucoTV's alerts are quiet too. For alerts with sound, keep GlucoTV on screen.
Do I need a separate subscription for the screensaver?
No. The screensaver is a free install. It uses the GlucoTV app's pairing on the same Roku, so your GlucoTV subscription covers both.
Can I put GlucoTV on more than one TV?
Yes. Each Roku pairs separately with its own code and has its own settings on your account page.
Do I need a Roku?
Not for GlucoTV itself. You can pair a computer instead and get a link that works in any browser, and the Roku and the browser viewer can be used at the same time.
