Non funziona nulla

Traduzione italiana assolutamente carente. Impossibile usare la connessione al sensore dexcom, impossibile verificare il numero di cellulare, ho ordinato Rizz, spero arrivi e poi funzioni

Stopped working June 28, 2025

This app is useless if the KnightRider does not attach to the sensor.
The KnightRider stopped collecting data on June 28, 2025 when I changed FreeStyle sensor.
How can I reset as if has never been connected. The app still displays the last reading captured. Everything shows connected but the KnightRider does not capture any data.

A HUGE DISAPPOINTMENT

I haven’t even had this device for a year and have had several issues, which is to be expected, however getting support from this company is like pulling teeth. I have wasted two libres without coming to a conclusion as to why the blucon isn’t reading the data and support has not replied to my emails in 5 days. I don’t know what to do but I am considering initiating a chargeback since I haven’t gotten support and the device is in warranty. I have just reached out to them again. It’s so disappointing. The weeks it did work were great but the lack of support and communication I actually insane. So so disappointing!!

Bad experience with iOS

The readings stop intermittently for 30 odd minutes

The 2 mins refresh with libre 1 makes this app useless

The support team keeps asking for logs and having shared it atleast 5 times. They still continue to keep asking for it with no solution in sights.

Please don’t buy of you are using Libre 1

Refresh in every 2 minutes not a 5 minute

The refresh rate of the FreeStyle Libre 1 sensor is every two minutes, which is inconvenient. Additionally, the Nightrider battery backup is only five days because of the frequent refresh rate, not the five minutes it used to be. Please consider improving these features.

Mexico diabetic

I can’t get the pro yellow sensors to work here only the free style libre ones sold at Costco

My daughter lives on it

My 10yr daughter is Type 1 diabetic. Her glucose sometimes goes low or high. Keeping track at night is a nightmare. This product Ambrosia Night rider wakes us up before any incident is going to happen. Now my daughter has been going to school with it having it connected to her apple watch 5 cellular. I can track her progress being away and alert her before incident is going to happen. 2 years ago this product used to disconnect from watch a lot… but now its improved 100 times and I can vote for it confidently. Great work

Frustrating and FAILS

Your LinkBluCon app is useless if the equipment it is designed to work with doesn’t work as it is supposed to. I went for months not being able to use the NightRider because you failed to upgrade the device to use FreeStyle’s with an expiration date after 9:40:2023.
Now either it has failed and you are reluctant to admit. I have tried all of the suggestions you have sent and none worked.
The NightRider is essentially a piece of junk,

Response from developer

Dear NCMom, Now we support Freestyle Libre 2, Libre 1, Libre Pro available globally (including in the United States). If you are still not able to use it please send an email to contact AT AmbrosiaSys.com with following information NightRider BluCon Purchase date: Firmware version #: You can find this information on the "About" screen of the LinkBluCon app after connecting the BluCon to LinkBluCon app. It should be 8.7 or above

looks like it could be good!

....but
won't work with Freestyle Libre 3 sensor-
was excited to use it! but doesn't support my sensor. site is a bit clunky-challenging to use-finally made purchase but only to find in didn't work-cancelled subscription
-they got my 10 bucks!
wished it worked!

Great concept, very poor execution.

Wasted money on this device, constant issues and battery barely lasts 2 days max.

Worst product I hv ever seen

It gets disconnected often and often

False Advertising

I blew $150 on this thing, and it never worked. After going back and forth with support, they finally admitted that it does not support the current version of the Libre 2 sensor, even though it is advertised as compatible. In spite of this, they refused to offer a refund and just stopped answering my emails.

So many bugs!

Widgets don’t display the same data as in the app and is way off. Device disconnects and then struggles to reconnect again. Watch app doesn’t display any readings. Support is also not very helpful when reporting an issue. Please fix!

App and sensor issues

I am struggling with either the new versions of the blucon app that was released recently or my blucon sensor. See serial number attached. The app CONTINUOUSLY crashes and gives me a message saying "time out". It also does very little recording from the libre sensor, perhaps 40% of the time in total. The Apple watch app basically does not sync to the app. Perhaps 20% of the time. The watch app also does not show the trend arrow indicator. This hasn't happened since the updated app release from February 24. This was one of the best features of the watch app complication and I make mention of it every time I provide you with support feedback. What is also bizarre is that when replacing the battery in the sensor it does not reflect that it is new. The battery indicator always shows red and suggests I need to change the battery. Furthermore the new batteries only last a few days before the app says the battery must be replaced and is depleted. I'm very disappointed in the new app and the sensor. Please can you investigate app improvements urgently.

Frustrated

I have been using the Blucon for almost a year but it last November 2022 and recently I’m getting an orange banner that says status unknown and the battery signal keeps telling me that the battery is low or to change the battery. I’m using Sony batteries I contacted through the app to Ambrosia to tell them about my problems. They sent me an invite for a test flight, but did not send me a pass code so I could sign onto the app therefore the app TestFlight cannot troubleshoot the bugs that are in your app for the Ambrosia link Blucon and I was on a chat with someone from Ambrosia but I can’t find that chat site any longer and someone from Ambrosia sent me an email told me not to change the battery. A few months ago Ambrosia requested me to send them the device and they would send a send a new one, instead they sent back the old device and said nothing was wrong with it. I bed to differ, either it’s their device or their app or both. $150 down the drain
I am fed up with Ambrosia customer service.

Waiting for Update

Waiting for new L2 app update. Only works after the update, so not working now.

Total garbage. Do not waste your money

Device does not work and customer support is nonexistent

Hi!

Cool development! Everything works fine except the widget! I'm really looking forward to the next update

When it works it’s great

I bought mine over a ear ago. Right out the box it worked fine with my iPhone 13 Pro Max phone. I use this with a Libre 2 sensor. I did try using the Libre Reader device. The Reader worked fine as long as I remembered to take it with me all the time. I would forget it on my way to work out picking up lunch somewhere. I went back to using my phone app and wanted something that made the Libre readings send to my phone like the Dexcom does. My insurance refused to give me the Dexcom option so I bought theBluCon Nightrider to try back in 2021. It worked great for all of 2022. Since March of this year I have had issues with it not connecting to my phone or it will connect but not show any of the readings from my Libre2 sensor. Sometimes the Libre2 sensor stopped working so I would remove it and put on a new sensor. The BluCon still doesn’t work all the time still. It’s out of warranty but support has been great working with me. Reboot your phone and disconnect Bluetooth and have it forget the BluCon then restart your phone, put a new battery in the BluCon then reconnect it and the Libre2 sensor and pray the BluCon works. It doesn’t till after the 6th time if I’m lucky. It knows when the 1 year warranty runs out.
