Android Question Can B4X develop apps with system performance?

[It.Behrooz]

Hello, I'm new to b4x. I want to know its ability. I've seen a lot of great apps developed with this great tool. In general, I am interested to know if this tool can be used to develop apps with system performance (like C++ for Windows)? Here are two examples of apps with this capability.
1- Can we use an app like "RAT Killer"?
To develop with b4a?
2. Is it possible to develop a program like "Kid Places" (which is useful for parental control). In this program, we define a number of users and specify the allowed apps for each one. Once this program is running, only authorized programs can be run and no other programs are available.
Thank you for your time.
Thanks to "Erel Uziel" and "Anywhere Software" for creating and supporting B4A

What is RAT KILLER? Do not expect everyone knows it.

2) I guess Kiosk-App is what you are searching for.

Edit: sorry I misunderstood.
As mentioned by Donmanfred, Kiosk app is possible to create using B4A.

Hello, I'm sorry, you're right.
RAT: Remote Access Trojan.
A Remote Access Trojan (RAT) is a type of malware that provides the attacker with full remote control over your system. When a RAT reaches your computer, it allows the hacker to easily access your local files, secure login authorization, and other sensitive information, or use that connection to download viruses you could unintentionally pass on to others. Source
I mean type of antivirus for this type of Trojan or key logger. I sea source code for RAT and keylogger developed by b4a.
Second item, kid places, like modal activity, that prevents users from apps on phone, unless authorized.
thanks for answering

1) I don/t think the issue is with B4X. You can write performant code with B4X. The issue is Android. If you really want to build an Antivirus software for B4A, good luck navigating all the restrictions of Android (which become more and more with each version) that may impede or make it difficult to write such a project. Some restrictions, such as related to acceptance of the app by the play store, can be avoided through side loading.

2) Can be accomplished either via Kiosk (device admin style) mode or abusing accessibility (at which point it cannot be uploaded to the play store).

Thank you oliverA,
1.I'm looking for the ability to report apps that have been communicate from my phone to others and send data for other devices. (via messaging and internet). like wireshark in Windows that can show packet of Data in network.
2. Your mention help me, I study Erel thread about Kiosk. I mean kiosk exactly.
