Kevin's Music Server for Android provides a web browser interface to control playback of audio files stored on most modern (4.x-11.0) Android devices. This allows the Android device to be used as a music server, in multi-room audio applications, among other things. I normally keep my Android phone docked, with a permanent USB connection to an audio DAC. This arrangement produces good quality audio playback, but I don't always have the pone within reach. It's awkward to fiddle with the little screen when it's docked, anyway. Providing a web interface – albeit a crude one – allows me to control playback from a web browser.Audio tracks can be selected using the browser from a list of albums, or directly from the filesystem (but see notes below). You can restrict the album listing to particular genres or particular artists rather than displaying all albums on the same page. Album cover art images can be displayed.Features:Simple web interface – works on most desktop web browsers and many mobile browsersIntegrates with the Android media catalogue – browse by album, artist, genre, composer, or trackSupports file/folder browsingMedia catalogue text searchEqualizerCover art (both baked-in and album-folder images)Playback control by headset or remote control

Android Virtual Pen allows to send pen input data from your android device to a pc host where it emulates a virtual pen. What distinguishes this solution from others, is emphasis on low-latency to provide the best drawing experience.Features:Adjustable pen pressure threshold such that you can move the pen-cursor without triggering an unintended click/draw actionAdjustable pen pressure sensitivity such that you can customize the force needed to be appliedSwitch between stretched and fixed display modeIn stretched mode, the android device screen is stretched and completely mapped to your PC primary screen. Note that this is required to fully reach the boundaries of your PC screen from your device but causes some slight distortion if the screen ratios (android vs PC) are not the same.In fixed mode, if the android device screen resolution fits into your PC screen, it is centered and mapped on that latter screen at a 1:1 ratio. This mode should incurr no distortion.Detect available usb devices and automatically save your settings for eachLimitations:Can only target one screen on the PC host (primary screen)Pen tilt is currently not supported (please do ask if you need this feature)No support on host side for MacOS and Windows

Auto Off BluetoothAuto Off Bluetooth is a lightweight utility for Android designed to preserve battery life and increase device security. The app monitors your Bluetooth connection status and automatically turns off the Bluetooth radio after 20 seconds if no devices are connected.How it worksThe app listens for Bluetooth state changes in the stack and for Asynchronous Connection-Less disconnection events in the background. When a device disconnects, the app starts a timer. If the timer expires without a reconnection, the app automatically disables the Bluetooth adapter to save power. If a Bluetooth device reconnects, the app postpones the Auto Off task until the next disconnect.PermissionsThe app requires the following permissions to manage your Bluetooth hardware:BLUETOOTH: Allows the app to see the status of connections.BLUETOOTH_ADMIN: Allows the app to toggle the Bluetooth radio on/off.BLUETOOTH_CONNECT: To interact with paired devices (required for Android 12+).

New: You can now configure the start and duration of the period, for example one week, 28 days, or even one year. Do you have an almost unlimited data plan and you never consume all your data? Lucky you! Unfortunately this app will be useless in this situation. On the other hand: do you have a limited data plan and it has happened to you: a) You always spend too much data on the first days of the period, and you have few left at the end? or b) You try not to spend too much data at the beginning of the period, and then you end with unused data? or c) You always wanted to know 'Did I spent too much already?' 'Am I above an average usage?'. Then this app will (I hope) help you! It shows your data usage (bottom bar, how much you already used) with an ideal 'average data usage' (top bar, how much you would have used by downloading the same amount of bytes every second in the period). This way with just one look you can check if you are above or below the 'average data usage'. - If the top bar is longer than the bottom: Good! You can download a bit more and still have at the end of the period. - If the top bar is shorter than the bottom: Not good! You need to stop using too much data, otherwise you'll end with no more left. Isn't this useful? I think it is, and that's why I (TrianguloY) published it. It doesn't contains ads, and it is absurdly lightweight, so give it a try. If you have any suggestion or comment leave one or send an email. DISCLAIMER!!!! Please note that the current consumption is measured by your device and may differ with your company measurement. I can't take responsibility if the displayed data usage is wrong. Permissions: - PACKAGE_USAGE_STATS - Permission needed to get the current usage from the usage service. No other data is retrieved nor used. More info here: https://developer.android.com/reference/android/app/usage/NetworkStatsManager.html#querySummaryForDevice(int,%20java.lang.String,%20long,%20long) - POST_NOTIFICATIONS - Permission needed to show a small message at the bottom of the screen (toast) when pressing the widget. The app does not send any standard notification. NOTE: there is no internet permission, there are no ads so it is not necessary. --------------------------------- The source code is available here: https://github.com/TrianguloY/Average-data-usage-widget

AwakeOnLANMobile enables you to send Wake On LAN (WOL) packets, allowing you to remotely wake up your devices over either a local area network (LAN) or over the internet. It supports IPv4 and IPv6 addresses. The application offers several features: Open Source: Licensed under GPLv3 License with zero advertisements and no account creation necessary. Local Storage: Add, edit, or delete device information for easy access. Network Scanning: Discover devices using either an IPv4 address or CIDR notation for subnets (e.g., 192.168.1.1 or 192.168.1.1/24). Choose between PING and TCP connect (sent to Port 443) packets for scanning. PING will require 1 second per IP address, while TCP connect will be faster. Theme Toggle: Switch between a light and dark mode theme to customize the appearance based on your preferences. The selected theme will be persisted even after shutting down the application. Developed with React Native (Typescript) and utilizes C++ turbo modules for native level socket access when sending and receiving packets. The ./cpp directory contains lightly modified code from 'https://github.com/nellogan/awakeonlan' and 'https://github.com/nellogan/netscan'. These are Linux commandline utilities that can be used in lieu of this application if your device supports a terminal (such as Termux or the new Android AVF Linux terminal).

BCR-GUI is a companion app for the great BCR (Basic Call Recorder) Android application.To manage BCR call recordings, you actually need to use a file manager... and thats not so user-friendly 😉. It's hard to "extract" call informations from audio filename, and its even harder to search them when the list grows. Such a feature was already requested, but chenxiaolong (the author of BCR) wants to keep BCR Basic; and I do agree with him! Call recording on Android is a hard work, and I'd like (and hope) him to stay focused on it... recordings management is a job made for BCR-GUI 😂.

# Prerequisites For this app to work and to get data the data on your watch, you need: - An Android phone - this app installed - Allow the app to draw over other app's permission and disable battery optimization. - xdrip app installed. - the Gadgetbridge app (bangle version) for the Android phone - A BangleJS - With this widget installed # App ## How to use it Make sure you have all the prerequisites from above. The watch should automatically start displaying values, if there is an arrow visible behind the value, the value is within the not-expired-yet time range changeable in the settings standard is 15 minutes. (I will probably change this in the future, to strike through the text to make expired values clearer). If you click on the text in the app, a test value of 18 as a raw value will be sent to the watch with a valid timestamp. This feature is used for testing if the connection works. Also, make sure to allow the app to draw over other apps's permission. ## Settings In the settings, you can: - Disable/hide the widget - Change the unit from mmol/L to mg/dL - Set a time at which old BG values expire # Developer Developed by Phil Roggenbuck (phrogg) # Disclaimer As well as xdrip you should not use this app to make medical decisions!

The author does not endorse or encourage any use of this software for unlawful or unethical activities. You are solely responsible for ensuring your use of this tool complies with all applicable laws and regulations. Bluetooth Low Energy (BLE) is a widely used wireless protocol that powers a huge variety of devices around you — from headphones, smartwatches, and fitness trackers to AirTags, IoT devices, game controllers, and even modern intimate gadgets. BLE devices communicate by broadcasting small packets of data, which can include device identifiers, metadata, and other information necessary for connectivity. These broadcasts, while essential for device functionality, can also be used to track your presence and movements. For example, a cheap pair of wireless headphones may expose a persistent identifier publicly. Anyone listening to BLE packets nearby — whether governments, companies, or malicious actors — could potentially use that information to track you without your consent. Fortunately, many modern devices implement privacy features in BLE to prevent tracking, such as randomized addresses and limited advertising. BLE Radar helps you distinguish between devices that protect your privacy and those that might be trackable. By analyzing BLE traffic in your surroundings, the app gives you insight into which devices are safe to use. Beyond analysis, BLE Radar can help protect you in real-time. The app can alert you when a suspicious device is nearby or if a device is moving with you over time, giving you an early warning against potential stalking or unwanted tracking. You can configure alerts based on device identifiers, types, or behaviors to fit your security needs. By making this app, the goal is to empower you with knowledge and control over the BLE devices in your environment. Understanding which devices are broadcasting trackable information and which are privacy-conscious allows you to make informed decisions about what you use, wear, and interact with daily. In general, the app is capable: * Scan, analyze and track Bluetooth devices around; * Create flexible filters for the radar; * Deep analysis of the scanned BLE devices, getting data from the available GATT services; * Gatt services Explorer; * Define the device type by metadata; * Define approximate distance to the device. Bluetooth Radar does not collect or send your personal or geolocation data. The project is fully opensource and available on GitHub.

BLEtoMQTT is an Android foreground service to provide a bidirectional bridge between BLE devices and an MQTT broker. A setup.json file defines MQTT parameters and BLE MAC addresses to scan for.For each BLE device detected BLEtoMQTT will discover all exposed services and characteristics creating MQTT topics for each. Those characteristics which are writeable will automatically be 'subscribed' from the MQTT broker.The author uses this application to connect remote custom ESP32 devices to his Home Assistant server via a Zerotier VPN. The app's source repository contains an example setup.json and a prebuilt apk used to monitor/control a boat on a mooring or at anchor. It also has more detailed setup instructions.
