Do you ever wonder how much speed you are getting on your downloads when you install something on your iPhone. I think about this all the time especially when I am downloading a big app from the App Store and my Internet appears to be acting up. DataMeter tweak, which is essentially an add-on for the Notification Center that helps users by adding a widget that displays this useful information to the user.
DataMeter works for both WiFi and Cellular Internet so you will know how much speed you are getting from both your home and cellular networks when using them. In addition to showing download speed the tweak also displays your IP, currently used data and remaining data in case you are using LTE. This makes DataMeter even more useful since you can also easily track your data and stay on top of your data allowance limits. It will show you your data usage by day, week and month.
The tweak also adds network data rate in the status bar, so you can view it when using apps. All the settings can be configured through Settings app. You can download DataMeter from Cydia for $1.99. It is available for iOS 9 and earlier versions.
