I use the Libre Link app.
I always carry my phone with me for work, navigation, email, and my pump. I would rather not carry the Libre reader too. I'd probably lose it anyway.
In addition, the reader needs to scan the sensor whereas the LibraLink app is automatically updated via Bluetooth.
I've only used the LibreLink phone app, but I'd like to know if the basic data presented by the app on the phone, could be shown by a watch.
I try to run every day and my rather large phone is a pain to carry with me. The Libre monitor is likewise not a handy thing to hold.
Given that our phones can easily display the Libre sensor's data (despite not having been designed to), is there any reason why the display device needs to be any larger or more cumbersome than a wristwatch or stopwatch? I don't need the multi-function aspects - just real-time BG readings.
