Signal Spy allows users to be better informed when it comes to their cellular service. It allows you to see signal strength and technology in real time. We can also tell you what LTE band you’re using on Sprint and T-Mobile so you can understand what speeds and features to expect. Signal Spy also keeps a history of all of your connections: when you connect and disconnect from WiFi, and what carrier you’re using! Pro Users can now see a history of Wi-Fi and Cellular connectivity along with signal strength and location!

For Project Fi customers, users will also be able to better manage their experience by easily switching between carriers with our dialer code shortcuts. Our network switching logging will be extremely useful to show you how often you switch between Sprint and T-Mobile networks. We also have a resources page within the app dedicated to resources that Project Fi users have found helpful with their service. Note though that our app will not automatically switch for you, and that all switch requests will revert after 2 hours. This is a ramification of using the dialer codes and cannot be controlled by Signal Spy.

Explanation of Permissions:
Location: In order to determine your LTE band, we need to access information about that tower. Accessing tower information requires the coarse location permission because of the data you can extract from that tower. We also use Location to determine where events took place (you can turn this off in settings)
Phone: In order to use the dialer, which is necessary for the carrier switch codes, we need to have the phone permission
Contact: In order to restore previous purchases on other devices, we need to verify your Google account and confirm add on payments. We don’t store your contact information outside of your device

“This app uses Accessibility services.”

User Reviews/Opinion:

  • Must-have for Fi subscribers. I mentioned in my review that I wished they’d capitalize the ‘m’ in “T-Mobile” in the “Launch Dialer Codes” menu, and they fixed it in the most recent release. Amazing!
  • Exactly what I needed, and didn’t even realize it. This satisfies the geek in me but also gives relative information. This is great for knowing which areas have the best real world coverage and how and when the phone changes between WiFi and Cell. Pro has neat perks as well. Looking forward to further development!
  • Update to review: Dialer Codes weren’t working, but after some troubleshooting, I found another app had replaced the stock Android Dialer. When I change it back, Signal Spy resumed working normally. Sorry for the confusion.
  • App constantly crashes on 8.+ A link to dialer codes are included but that is not useful if you don’t have service. Leaving accessibility mode on is hindering. Comment responses to by the developer to customers are patronizing and rude.
