App Name: Dangerous App Checker (ver.1.2) Price: Free (as of August 12) Category: Tools Development: 9256 Device used: Nexus 5 Recommendation: ★★★☆☆
"Dangerous App Checker" is an app that can check the permissions granted to installed apps. Permissions that can lead to personal information leaks are scored and displayed, so you can easily grasp the degree of risk of each application.
When you start the app and tap "App Check" from the five menus that appear, the installed apps will be checked, and their "access authority count" and "risk level" will be displayed. . Based on this information, if there is an application that is determined to be dangerous, it is how to use this application to manually delete it.
Each access privilege is given a score (0-3 points) according to its degree of risk. For example, "making phone calls", "sending and receiving SMS", and "changing general system settings" have a risk level of 3, "taking pictures and videos" has a risk level of 2, and "disabling device sleep" has a risk level of 1. . By displaying these total scores, it is a mechanism that displays how dangerous the app is.
The advantage of this app is that it displays the risk level numerically, so even if you don't have much knowledge about Android permission settings, you can easily understand the risk of information leakage. On the other hand, even if the permission is necessary for the operation of the app, the function that leads to information leakage is added to the risk level score, so if you judge only by the risk level value, even the originally necessary application will be uninstalled. I might lose it. In that sense, it is an advantage, but there is also a danger that it can be a disadvantage if used incorrectly.
These notes on the score system are explained in detail in the category "Access Permissions and Privileges" that can be accessed from the home screen, but the volume is just like reading material, and the content is rather painful for beginners. is. Also, depending on the screen, the back button does not work, and there are places where it is difficult to distinguish whether it is a button or a design. Since the concept is ambitious, I would like to expect improvements in clarity in areas other than the score system.
