Great app(not anymore)
Most of the times it works right, but sometimes it acts weird. Sometimes it doesn’t keep track of the cellular data being used, but adds it later that day to a wrong timestamp(even though cellular was turned off). It also sometimes registers the same data twice on different timestamps. Other than that it works great and is one of the best ways to keep track of data usage, there are not many other good workings apps(only this app and My data Manager keep good track off cellular data). Update april 2025: It gets worse every month. The app becomes unreliable/useless now. Update August 2025: Yeah… even worse now. Data is off, regularly opening the app, but shows I used 165MB. Other app and iPhone itself don’t report this usage. 1*
