This is a handy tool for finding out the processes that are running with a more informative display than Activity Monitor. It seems to depend on user feedback for descriptions of the processes, which, if present, can be useful in identifying what a process is for. The App does have in-house purchases. The purchase is for removing left over files from uninstalled Apps and costs $5.00.. So a full functioning App is not really free. Unfortunately the developer does not list the optional paid features or the cost on their website or in the App description so that the user can make an informed decision before installing the App. This 'Bait & Switch' is what driving a lower 'star' rating in my review. Two desired features is missing from this App. These are the ability to kill a process and the ability to delete it within the App. If these are added in a future release I hope that the developer adds adequate warnings and with administrative access as deleting some process that are not user processes could damage the operating system and require a reinstall. I also question charging for App features when the App seems to depend on user input to add descriptions in order to improve its usefulness. Given the limited time I have spent exploring it, along with a lack of information about the paid options, there might be other features that are purchases or some of the available free features might become disabled after a period of time unless paid for. Given that the App is at version 1.0 I feel it has great promise. If the App was forthcoming about the in-app purchases and had a 'kill process ' tool it would have gotten 5 stars.
