The Ultra iMeter Cydia tweak will always keep crucial system information in view without leaving the app your are currently running along with being able to track your network allowance or disk space.
With the tweak installed you get access to an “iMeter bar” that is essentially a status bar overlay that will be displayed when you execute an Activator command of your choice. In this “iMeter bar” you will see stats like network, disk, ram and cpu usage. The bar will even show up in fullscreen applications if you call on it which is wonderful for those who need to see the device/app performance (meaning it is very useful for developers).
Besides its use with app developers and those who want to keep a close eye on system performance, it can also be used for those with limited data plans. You can set limits for both cellular and WiFi usage and configure popup warnings to appear when you get close to reaching these limits.
There is quite a few customizable options in the Settings app that include setting when to receive warnings, the update interval, specifying display options and much more.
If you are interested in the Ultra iMeter Cydia tweak you can find it in the BigBoss repo for $1.99. Be sure to let us know what you think of the tweak in the comments section below.
