User reviews
These summaries are automatically generated weekly using AI based on recent user reviews.
Google Play Store does not verify user reviews, so some user reviews may be inaccurate,
spammy, or outdated. Pros
- Helps track network connections and switch carriers as needed.
- Convenient to have dialer codes in one place.
- Responsive developer addressing user feedback.
- Functional widget (if working) that provides quick access to network info.
Cons
- Recent updates have removed the widget, frustrating many users.
- Inconsistent reporting of SSID and network type (e.g., showing 4G when on 5G).
- Foreground service occasionally disables itself.
- A constant notification is seen as less useful compared to a widget.
Most mentioned
- The widget has been removed or is not functioning properly.
- Issues with SSID displaying as 'n/a' and inconsistent network reporting.
- Developer is responsive to feedback but app improvements are needed.
User reviews
The foreground service tab has to be reset about once a week or so. Not sure why it turns off. Other than that, works great to know which network you're on with Fi. Especially helpful to know when to switch if you know your local towers.

Patrick Fleming, 2022-08-09Helpful on Fi to force connection to us cellular which the phone can't seem to do on its own. One issue is SSID now just reports as n/a.
