Data info on specific apps doesn't work – DataMan Pro Review

Got the PRO version so I could see what apps use the most data. But there is no app data in the Dataman app. Just an empty "apps" tab. Emailed the company to ask about this, no response. Pricey considering one of the main features doesn't function at all. The "Time" tab does work but that info isn't useful whatsoever. I'd rather know what apps are using what amount of data. The main interface design is OK. The % number on the main screen could be smaller (it's giant) and other info could be housed on the main – like the top 3 data using apps. 2 stars due to nonfunctioning feature and high price.
