When attempting to measure your iPhone’s wireless signal strength, be it cellular or Wi-Fi, you will often see dBm (decibel milliwatts) used for the unit of measure for your received signal strength.
iOS developer Julio Verne sought to make this information easier to access from jailbroken devices, and as such, created a free and convenient jailbreak tweak called SignaldBm.
As you’ll see for yourself in the screenshot examples above, SignaldBm simply adds your current internet connection’s dBm measurement to the Status Bar.
Once installed, SignaldBm adds a dedicated preference pane to the Settings app where users will be able to customize a number of settings:
Options here include:
- Enabling or disabling SignaldBm on demand
- Enabling Wi-Fi dBm measurements
- Enabling cellular dBm measurements
- Choosing a preferred text color for the dBm measurement
- Adjusting the text size for the dBm measurement
- Adjusting the width of the dBm measurement
- Adjusting the height of the dBm measurement
- Resetting all options to their defaults
With dBm measurements, the closer your measurement is to 0 on the number line, the better your signal strength is. Having said that, a measurement of -77 dBm is better than having a measurement of -100, and so forth.
While it’s indeed possible to check your dBm measurement on non-jailbroken handset, doing so is a bit of a hassle, and that’s why SignaldBm is a recommended step toward automating the signal strength check process on pwned handsets.
If you’re interested in trying SignaldBm for yourself, then you can download it for free from Julio Verne’s personal repository via your favorite package manager app. The tweak supports jailbroken iOS 13 & 14 devices.
