I purchased the Nightrider device to provide continuous read out of my freestyle libre sensor, to avoid loss of data if I go more than eight hours between readings, and to upload the glucose data to Apple Health
The iPhone app accesses the sensor data OK. more or less. It is a very noisy app. After connecting it complains that the Nightrider battery is low, correcting itself only after a few five minute cycles before it reads correct data. It regularly loses connection to the device, and then regains it five minutes or so later. From time to time it provides urgent alarms every 30 seconds or so, so much so that I had to disable the notifications completely.
At first managed to upload data to Apple Health, which is why I bought the device. But then, after I went for a walk without carrying my phone, it disconnected, and never manage to connect to Apple Health again. Even after multiple resets, repairing, uninstalled and reinstalled LinkBluCon . I managed to get it to read data from the sensor and displayed on the iPhone, but never again to get it to upload to Apple Health.
I tried to connect it to my watch, which I pretty much always wear, even when I leave my phone behind. But I have not yet succeeded in doing so. I don’t care about seeing my blood sugar or receiving alerts on my wrist since I have controlled my diabetes via diet more or less, but I was hopeful that pairing the device with my watch would avoid these complaints about being disconnected
So far, mediocre software quality, but I could live with it if the Apple Health upload problems were solved.
The scary thing, the thing that makes me think that this might actually be malware/spyware, is that LinkBluCon insists on being able to read many many metrics from Apple Health. Almost all of the metrics, if not actually all. Why would a device that I use to read my blood sugar need to know my cervical mucus quality (I am male) or my sexual activity, or my biotin levels?
Like I said, either they are stupid, reading much more than they need to, or they are selling your Health data. probably both.
I suspect that my problem reconnecting to apple health is that after a while I denied the this app app access to all of my Apple Health data, except for the right to write my blood sugar data. However, even when I later restored them access to all of my Apple Health data in an attempt to reconnect to Apple Health, it still refuses to work.
anyway, they have had access to all of my health data, i.e. have potentially completely invaded my medical privacy. I took that chance in the hope of uploading my blood sugar data to Apple Health. It did not work. I am not at all sure that it is worth working with them to get it to work, certainly not until they fix their privacy implementation. If you value your privacy, I suggest that you not use LinkBluCon, and possibly not the nightrider device, unless you can find other software that it works with. A further red flag is the password management they provide on their website for affiliates: it gives every indication of them keeping a copy of the password. This is well known to be poor security practice - UNLESS they intend to spy on you.
Like I said, they are either malware/spyware, or not very good programmers, unaware of best practices in security and privacy. Frankly, I am surprised that Apple allows LinkBluCon in the iPhone and watch app stores.
