The LinkBluCon app can be used with BluCon (TransAm or NightRider) with Abbott's FreeStyle Libre sensor to get near real-time glucose trends.

Type 1 and Type 2 diabetic patients can use this app to connect their iPhone to a BluCon device to read the Freestyle Libre sensor every 5 minutes. Readings are available to the user through a user-friendly and intuitive GUI. This relieves the user from having to scan their sensor every 5 minutes.
LinkBluCon connects to BluCon over a Bluetooth connection to display glucose trends. It also provides a logbook to view past readings. No sign-up is required.

LinkBlucon app can share the glucose readings with the healthKit by enabling the option in settings. User can see his glucose levels in healthKit.

Please note that a fingerprick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycemia or impending hypoglycemia is reported by the LinkBluCon app or when symptoms do not match the LinkBluCon app readings.

Pretty Decent!

I had the Eversense implant CGM, but the transmitter technology wasn’t the best. I recently changed back to the FreeStyle Libre sensor, but missed the constant glucose values. I got the NightRider to supplement that continual reading technology, and it’s pretty darn good. The UI is better than some glucose apps, the connection between NightRider and my phone was easy.

The only thing I don’t like about this App is that it either doesn’t connect to Apple Health, or if it does, I can’t figure out where to turn that connect on. So... developers... if you could, PLEASE get this app to connect with Apple Health!

Night rider and App.

After being inundated with emails touting the direct to watch connectivity, I bought a Night Rider. After some back and forth about delivery with customer care, I received delivery. Luckily it was received after the software update a few days ago to support the US 14 day sensor. If not, it would not have worked at all. Per customer care, the direct to watch functionality for the US 14 day sensor should be available in a few weeks. Nothing about this is mentioned anywhere in their marketing materials. I only bought this for the direct to watch function. Charging $25 for shipping a $9 priority mail envelope is also obscene.

Update July 17,2020

Decided to give it another try. The direct to watch functionality works. The app was installed with the complication. I added the complication to my watch face and it works as expected. Then the app pops up on your screen. I have still to find a way to see my watch face on wrist lift or crown press.... the open app is always displayed. It appears to run as an ACTIVITY which on Apple’s software is always displayed with wrist lift on. A crown press to required to get back to your watch fact.... which displays your data via the complication. Dear developers, what am I missing?

Developer Response ,

Please install the latest version of the app to see readings on the Apple watch, it was released last month, sorry for the confusion. Please reach out to support to get the refund of shipping. Could you please provide an update? If the device is not working for you as expected please send it back for refund within next 2 weeks.

Cannot register in app or online

I cannot register in the app because it won’t let me enter or select a birth year. There is also no place online to register. The app is close to useless if I can’t share the data with my doctor! Also applying the Nighrider to the Libre 2 sensor was NOT as easy as the video suggests. Mine fell right off no matter how hard I pushed on it. I had to use the arm band that came with it for it to stay in place (also took a while to wrangle it in the right place and tighten almost as tight as a blood pressure cuff). Then even though it was reset and paired with the app on my phone, it wouldn’t connect to the sensor and pull a reading, at least that’s what it looked like. After 10-15 minutes pushing it in over the Libre sensor it FINALLY started posting readings. Update just 15 minutes later: now it’s not posting readings again. I think when I left the room for 5 min or so the app just stopped the readings and won’t start again when I got back.

ZERO APP SUPPORT!!!!!!! If you click on app support you you get a page not found error on their website. My review is NOT showing up.
