YOUR NEXT STEPS
Start with the role of your iPhone
Sending your own readings?
Choose the app that already receives your sensor data. Its Nightscout connection sends those readings to your personal site.
Following someone else?
A follower app such as Nightguard reads from an existing Nightscout. The person sharing their readings must have a working upload connection first.
Check both ends
Open Nightscout in Safari and compare its latest reading time with the source app. A blank page of readings usually means the data source still needs connecting.

A few useful answers
Do I need a Dia.best iPhone app?
No. Nightscout opens in Safari and works with compatible iPhone apps. Dia.best does not currently offer an iPhone equivalent of its Android app and Home screen widget.
Is Nightguard the app that sends my sensor data?
Nightguard is a follower: it displays data already present in Nightscout. Start by connecting a source app, then set up the follower.
Which Libre connection should I choose?
Start with your exact sensor model, region and current app. Support varies across Libre versions; the xDrip4iOS guide explains the supported iPhone paths.
Already using Nightscout?
Existing free Nightscout accounts keep working as before. Start a monthly or annual subscription without signing in first. You can connect your own Nightscout to Dia.best for free.
