PCAPdroid is a privacy-friendly app which lets you track and analyze the connections made by the other apps in your device. It also allows you to export a PCAP dump of the traffic, inspect HTTP, decrypt TLS traffic and much more. PCAPdroid simulates a VPN in order to capture the network traffic without root. It does not use a remote VPN server, instead data is processed locally on the device. Features: * Log and examine the connections made by user and system apps * Extract the SNI, DNS query, HTTP URL and the remote IP address * Inspect HTTP requests and replies thanks to the built-in decoders * Inspect the full connections payload as hexdump/text * Decrypt the HTTPS/TLS traffic and export the SSLKEYLOGFILE * Dump the traffic to a PCAP file, download it from a browser, or stream it to a remote receiver for real-time analysis (e.g. Wireshark) * Create rules to filter out the good traffic and easily spot anomalies * Identify the country and ASN of remote server via offline DB lookups * On rooted devices, capture the traffic while other VPN apps are running If you plan to use PCAPdroid to perform packet analysis, please check out the specific section of the manual. Join the PCAPdroid international community on Telegram or on Matrix.

This app allows you to easy convert static units to adaptive units with three steps: * set width of the screen; * set height of the screen; * enter value to get its converted to vw and vh value.

Set up network packets based on IP, port, Hex or ASCII data and specify either UDP or TCP protocol. Results are stored in the live traffic log. Packets in the log can be easily saved and sent right back out to another destination. In addition to sending packets, Packet Sender has a built-in TCP and UDP server running on the port numbers you specify. 1x1 widget support allows sending a packet direct from the home screen.

Reboot your phone in a given interval on a specific time and start a specific application after reboot. The idea is to restart Android and an application periodically to clean up cache and memory leaks if the application has to run over a long time. And if you don't need to restart an application, still this can help to close memory leaks. No background services - reboot is scheduled by system AlarmManager. Before reboot is applied, all apps get a shutdown call to save there data. This helps to prevent data loss! Configuration allows * selection of reboot interval from every day to every 30 days * selection of reboot time from midnight to 11pm * selection between hard reboot (complete restart) or soft/hot reboot (only restart apps) * selection if you want to start an app automatically after reboot * selection of any app to be started automatically after reboot

You can check the full source code in this repository — there is no malicious activity. If you disable Play Protect, Android may still periodically show warnings. This seems to be because Android stores previously detected warnings and repeats them, even after Play Protect is turned off.

RKNHardering is an Android application that detects VPN and proxy usage on a device, implementing the Russian Federal Service for Supervision of Communications (RKN) methodology for identifying circumvention tools. The app runs nine independent detection modules in parallel and produces a combined verdict: - GeoIP — checks the public IP against GeoIP databases and hosting/proxy signal providers - IP Comparison — compares responses from RU and non-RU public IP checkers - Direct Signs — inspects NetworkCapabilities, system proxy settings, and installed VPN apps - Indirect Signs — analyzes network interfaces, routing table, DNS, dumpsys VPN output, and localhost proxy listeners - Location Signals — reads MCC/SIM/cell/Wi-Fi data and queries BeaconDB for geolocation - Bypass Check — scans localhost for open SOCKS5/HTTP proxies, Xray gRPC API endpoints, and detects underlying network leaks - CDN Pulling — sends HTTPS requests to trace endpoints to determine the apparent public IP - Call Transport — checks STUN and MTProto availability to detect traffic tunneling - Native Signs — performs JNI-level checks of interfaces, routes, /proc/self/maps hook markers, and root indicators The final verdict (NOT DETECTED / NEEDS REVIEW / DETECTED) is calculated by VerdictEngine using a weighted combination of the module results. Minimum Android version: 8.0 (API 26). Source code: https://github.com/xtclovver/RKNHardering

Say hello to a safer, transparent, and secure Android. VPN: Connects to multiple WireGuard VPNs of your choice. Safe: Reveals network activity of installed apps and lets you disable, uninstall, or firewall them. Secure: First line of defense against spyware, ransomware, and malware that steal personal information and takeover accounts. Protects from DNS manipulation typically employed to censor websites, social media, and messaging apps. Fast: DNS Servers deployed to 300+ locations world-wide to ensure your internet is as fast and highly available as it can be. Open: Open source and free of any trackers. ***Features*** Firewall: Prevent apps from connecting to the Internet. Block spyware, malware, ransomware and more. A firewall blocks any app connecting to the Internet over WiFi or Mobile data. Since most forms of surveillance require the data to be sent the network to a server, firewalling them effectively mitigates the threat (File Managers, Alarm Clock, Calculator are few such examples of apps that do not require any Internet access to function). The firewall feature uses Accessibility Service to detect and firewall background applications. Monitoring: Keep tabs on incoming and outgoing Internet traffic. If enabled, the connectivity logs are collected and analyzed. Automated reports flag previously unknown or suspicious connections, and reveal the extent of attempt to steal data by spyware networks. In our tests, around 60% of the traffic is flagged and reported as being initiated by known spyware. Logs generated are made available in near-real time to the user for their own analysis. WireGuard: Secure outgoing Internet traffic. The app uses fast, modern, light-weight, and secure WireGuard protocol to encrypt outgoing connections to any compatible VPN provider of your choice. Anti-censorship: The app encrypts your internet connection to Domain Name System (DNS) server run by Rethink with presence in our 300+ locations world-wide. DNS servers are the address book of the internet: A DNS server provides the exact addresses you need to visit a website or open an app. Data Monitor: Track per-app and per-connection Mobile or WiFi data usage.

Over 1024 levels from very easy 1 minute ones to extremely hard, which could take hours to solve. RoboZZle is a cool programming puzzle game invented by Igor Ostrovsky. Your program will control a robot to collect all items from 2D tri-colored field. You can move, turn, repaint cells and call very short (in most cases) functions.

Allows you to use I/Q packet source in your Android applications. All you need is to launch an intent in the form "iqsrc://rtl_tcp_arguments" where you replace rtl_tcp_arguments with the arguments that you want your application to run rtl_tcp with and the magic will be done behind the scenes. This driver could be used by third party applications to implement Software Defined Radio. It does not require root for Android 3.1 and above.

Features: - Search (apps, stack traces) - Crash preview in notifications (configurable in settings) - Combination of the same crashes / apps to avoid repetitive lists (configurable in settings) - App blacklist - Quick actions in notifications to copy / share stack traces

Shows the screen configuration for an Android device, including the screen size (small, normal, large, xlarge) and the density classification (ldpi, mpdi, hdpi, xhdpi). Also shows other screen metrics, as well as the calculated screen size in physical units. Users can email the report or share it to other apps. This information is useful for developers producing layouts for their applications, or to assist them in customer support scenarios.

Provides low level access to the devices sensors. Readout is presented in a graph for easy side by side comparison with other devices. Usage: * Touch desired sensor on the list screen in order to start the readout. Long touch the sensor to show it's details. Use "Back" to close the details dialog again. * On readout view, touching the graph will stop the sensor from being read out. After stopping, the graph can be scrolled and or panned by a drag or pinch gesture. To restart the readout, return to the main sensor list and select the sensor again.
