openDSP-4x4
APK
openDSP-4x4 is an open-source control app for the t.racks DSP 4x4 Mini Pro, a 4-in / 4-out XLR digital signal processor that otherwise ships with Windows-only editor software. It lets you set the DSP up from an Android phone or tablet — at the desk or on stage — connected over USB-OTG. The control protocol was reverse-engineered clean-room, purely by observing the device's USB-HID traffic and probing it (write a known value, read it back, match the bytes). The same protocol drives a zero-install desktop web app (WebHID) and this Android build. On Android the UI runs in a WebView and reaches the device through a small native USB-host layer, because no Android browser can talk to a HID device. Features: * Input/output routing matrix. * Gain, mute and polarity per channel. * 7-band parametric EQ with high- and low-pass crossovers. * Compressor, gate and output delay. * Preset recall and store (7 device slots) as quick launch pads. * Live input/output meters and full device-state read-back on connect. Privacy: * No analytics, no telemetry, no network connections — the app talks only to the DSP over USB. Plug the DSP into the phone with a data-capable USB-OTG cable, tap Connect, grant the USB permission, and the app reads the device's current state and is ready to edit. Independent, clean-room interoperability project. "the t.racks" is a trademark of Thomann; this app is not affiliated with or endorsed by Thomann.

openScale
APK
Monitor and track your weight, BMI, body fat, body water, muscle and other body metrics in an open source app that: * has an easy to use user interface with graphs, * doesn't require you to create an account, * can be configured to only show the metrics you care about, and * respects your privacy and lets you decide what to do with your data. Bluetooth scales openScale has built-in support for a number of Bluetooth (BLE or "smart") scales from many manufacturers, e.g. Beurer, Sanitas, Yunmai, Xiaomi, etc. (see model list below). Together with our users we constantly improve and extend the set of supported scales and in many cases pick up where the original app falls short. For scales without Bluetooth, or Bluetooth scales not (yet) supported by openScale, measurements can be manually entered in a quick and easy way. Privacy This app has no ads and requests no unnecessary permissions. The location permission is only needed to find a Bluetooth scale. Once found the permission can be revoked (or never granted if Bluetooth isn't used). Supported metrics Weight, BMI (body mass index), body water, muscle, LBM (lean body mass), body fat, bone mass, waist circumference, waist-to-height ratio, hip circumference, waist-hip ratio, visceral fat, chest circumference, thigh circumference, biceps circumference, neck circumference, body fat caliper and BMR (basal metabolic rate). Each entry can also have an optional comment. Note: don't worry if you think the list is too long: metrics you don't use can be disabled and hidden. Other features * Resizable widget to show the latest measurement on the home screen * Configure your weight unit: kg, lb or st * Set a goal to help keep your diet * Displays all your data on a chart and in a table to track your progress * Evaluates measurements and gives a quick visual feedback to show you if you're within or outside the recommended range given your age, sex, height etc. * Import or export your data from/into a CSV (comma separated value) file * Supports body fat, body water and lean body mass estimations based on scientific publications. Useful if your scale doesn't support those measurements. * Support for multiple users * Partially or fully translated into Catalan, Chinese (traditional), Czech, Dutch, English, French, Galician, German, Greek, Italian, Japanese, Norwegian Bokmål, Polish, Portuguese (Brazil), Romanian, Slovak, Spanish, Swedish and Turkish * Optional dark theme Supported Bluetooth scales * Custom made Bluetooth scale * Beurer BF700, BF710 and BF800 * Digoo DG-S038H * Excelvan CF369BLE * Exingtech Y1 * Hesley (Yunchen) * MGB * Medisana BS444, BS440 * Runtastic Libra * Sanitas SBF70 * Silvercrest SBF75 * Xiaomi Mi scale v1 and v2 * Yunmai Mini and SE * iHealth HS3 * Easy Home 64050 * and many more Please see Wikipage for the full list and the level of support for each scale.

opsu!
APK
opsu! is an unofficial open-source client for the rhythm game osu!, written in Java using Slick2D and LWJGL (wrappers around OpenGL and OpenAL). opsu! runs on Windows, OS X, and Linux. A this libGDX port also supports Android devices. '''Beatmaps''' opsu! requires "beatmaps" to run, which contain the songs and gameplay data. These can be downloaded directly through opsu! in the downloads menu, or manually from the [https://osu.ppy.sh/p/beatmaplist osu! website] (requires registration) and mirror sites like [http://bloodcat.com/osu/ Bloodcat]. Place any manually downloaded beatmaps (in .osz format) in the `Import/` directory for opsu! to unpack them automatically. If osu! is installed, opsu! will attempt to read beatmaps from the osu! installation location. The beatmap directory can also be changed by setting the "BeatmapDirectory" value in the generated configuration file. '''First Run''' opsu! will parse all beatmaps when launched, which can take a while for the first time. If no beatmaps are found, the game will prompt you to download some to get started. Game settings can be changed in the options menu, accessed by clicking the "Other Options" button in the song menu. The "Music Offset" value will likely need to be adjusted initially, or whenever hit objects are out of sync with the music. '''Directory Structure''' The following files and folders will be created in the opsu folder in storage as needed: * `.opsu.cfg`: The configuration file. Most (but not all) of the settings can be changed through the options menu. * `.opsu.db`: The beatmap cache database. * `.opsu_scores.db`: The scores and player database. * `.opsu.log`: The error log. All critical errors displayed in-game are also logged to this file, and other warnings not shown are logged as well. * `Songs/`: The beatmap directory (not used if an osu! installation is detected). The parser searches all of its subdirectories for .osu files to load. * `Skins/`: The skins directory. Each skin must be placed in a folder within this directory. Any game resource (in `res/`) can be skinned by placing a file with the same name in a skin folder. Skins can be selected in the options menu. * `Replays/`: The replay directory. Replays of each completed game are saved as .osr files, and can be viewed at a later time or shared with others. * `Import/`: The import directory. All beatmap packs (.osz) and skin packs (.osk) are unpacked to the proper location. All replays (.osr) are moved to the replay directory, and their scores saved to the scores database. * `Screenshots/`: The screenshot directory. Screenshots can be taken by pressing the F12 key. * `Natives/`: The native libraries directory. * `Temp/`: The temporary files directory. Deleted when opsu! exits.

phyphox
APK
Did you know that you are carrying a 3D magnetometer? That you can use your phone as a pendulum to measure earth\'s local gravitational acceleration? That you can turn your phone into a sonar? phyphox gives you access to the sensors of your phone either directly or through ready-to-play experiments which analyze your data and let you export raw data along with the results for further analysis. You can even define your own experiments on phyphox.org and share them with colleagues, students and friends. Selected Features: - A selection of pre-defined experiments. Just press play to start. - Export your data to a range of widely used formats - Remote-control your experiment through a web interface from any PC on the same network as your phone. No need to install anything on those PCs - all you need is a modern web browser. - Define your own experiments by selecting sensor inputs, defining analysis steps and creating views as an interface using our web-editor (http://phyphox.org/editor). The analysis can consists of just adding two values or using advanced methods like Fourier transforms and crosscorrelation. We offer a whole toolbox of analysis functions. Sensors supported: - Accelerometer - Magnetometer - Gyroscope - Light intensity - Pressure - Microphone - Proximity - GPS *some sensors are not present on every phone. Export formats - CSV (Comma separated values) - TSV (Tab-separated values) - Excel (if you need other formats, please let us know) This app has been developed at the 2nd Institute of Physics A at the RWTH Aachen University. -- Explanation for the permissions requested If you have Android 6.0 or newer, some permissions will only be asked for when needed.
