Observe at your own pace
Start or stop a scan when you choose. Review received announcements and when they were last observed. Enable the measurement log if you want to export a CSV manually.
Release in preparation
Nearby Signals
A clearer view of the signals around you.
Nearby Signals helps you explore Bluetooth signals in your surroundings and record observations for later reference. It is designed for on-device use, with no account or app server.
An optional field log
You can optionally enable CSV journaling and export a file manually. Journaling is off by default; exported files may include device identifiers and other nearby-device details.
Designed with limits in mind
Bluetooth scanning depends on iPhone settings, permissions, and the radio environment. Results are observations, not a guarantee that every device will be detected or identified.
Nearby Signals is not yet available on the App Store.
