Not only the app is hard to manage, the data impossible to understand, but the output of the logs I received are from 2019 and seem be to belong to a completely different device. To crown everything, the app is now flagged by my firewall. And I paid for the full add-ons! How is it possible to pull log entries from 2 years prior to the device being activated ?

Great app. More info than the average user needs. Usually use leads to research on my part. Great for understanding what apps are doing. I use it to see if apps are behaving normally. I have used this as a basis for uninstalling apps that are always active even though I have not used then recently. One drawback, recent updates asks to purchase even though I have purchased pro key. Pop up occurs. I launch pro key. Sometimes popup goes away, sometimes not. 6 to 8 times over last 2 months.
