A I use the Libra, but added the Ambrosia NightRider to it. The night rider reads the glucose level every 5 minutes without scanning, basically turning the Libra into a cGM.
Then, I paired the NightRider with the Spike app (most use X-drip, but I have Spike). These apps let you program in alarms as well as add notes about food, carbs, insulin, activity, and such to your glucose graph. They also let you calibrate the readings so they are more accurate.
I don’t recall the cost of the Night Rider, but the app is free by request through test flight. I believe it is only for I phones.
The only problems I have with NightRider is it is not waterproof, so I have to take it off to shower. You also have to figure out how best to attach it. I’ve used large bandaids in the past, but now use a roll of tegaderm type tape from Amazon, so I can shower without losing the connection.
PS In the US the Libra takes 12 hours once activated before it will read. If you place and activate the new sensor without removing the old, the Night rider will continue to read the old sensor. I don’t know for how long, but it definitely lets you get readings without a 12 hour break.
