Apps

Haven is a Free and Open-Source app that leverages the "Work Profile" feature of Android to provide an isolated space that you can install or clone apps into. Haven uses the application id io.github.kennethchoinfosec.haven, so it installs as a separate app and does not upgrade or replace existing installs of the original app. The main use-cases of Haven include: - Installing apps inside a work profile for isolation - "Freeze" apps inside the work profile to prevent them from running or being woken up when you are not actively using them - Installing two copies of the same app on the same device Note that Haven depends on the Work Profile feature of the Android system, so any bugs related to Work Profiles in the Android-derived system you are using will affect Haven. In addition, Haven can only be as secure as the Work Profile implementation.

Haven is an app for people needing a way to protect their private sphere and possessions without compromising their own privacy. It turns the on-device sensors of any Android phone into a motion, sound, vibration and light detector, alerting you of unexpected guests and intruders in your physical spaces. By combining monitoring and device storage, with secure communications technologies, like Signal and Tor, it prevents the worst kind of people from silencing citizens without getting caught in the act. By protecting investigative journalists, human rights defenders, and people at risk of forced disappearance, a new kind of herd immunity is created.Safety through SensorsHaven only saves images and sound triggered by motion or volume, storing everything locally on your device. Position the device’s camera to capture visible motion, or place your phone somewhere discreet to listen just for noises. Get secure notifications of intrusion events instantly, and access logs remotely at any time.Sensors monitored for measurable change, recorded to the device event log:Accelerometer: Motion and vibration of phoneCamera: Motion in the phone’s visible surroundings from front or back cameraMicrophone: Noises in the environmentLight sensor: Triggered by sudden light changesPower: Detect device being unplugged, running out of battery or being shut downProject TeamHaven is a collaboration between the Guardian project, and the Freedom of the Press Foundation, which generously funded the Prototype stage.

Shows a notification icon in the status bar when headphones are plugged into the phone. Shows a different icon when a headset is attached. Both 3.5mm audio jack devices and USB headphones/headsets are supported. The app aims to be a tiny as possible. No ads, no analytics - just its core functionality. After installation, you have to start the application at least once. Then it will be running as a background service that shows the headset status icon whenever the headphones are plugged in. I wrote the headphone indicator app because I was immensely unsatisfied with apps like (google forced me to remove the name) which are over 2 MiB in size, but 99% of their code is only related to advertisement.

Make your smartphone or tablet battery last longer! Good range to aim for when charging a Li-ion battery is from about 40 to 80 percent in one go. A bunch of tiny charges throughout the day is your second best bet, and going from zero to 100 and then 100 to zero on a regular basis will put the most strain on your lithium-ion battery. Healthy Battery Charging notifies you when to plug or unplug your phone from the charger in order to improve the battery life. The app itself is optimized for low battery consumption, running in the background and checking the battery level every 15 minutes (configurable). The exact timing of these checks depends on the Android OS, which might schedule them alongside other tasks or delay them when in sleep mode. As a result, the battery level may slightly exceed the high threshold while charging or drop slightly below the low threshold while discharging before you receive a notification.

Simple way to estimate the heart rate. Please do not use it for medical purposes ! This utility works by covering the flash as well as the device's camera with a finger, and waiting for 10 seconds. It works best when the person stays still, and the environment is dark. The phone analyzes the amount of red captured by the camera, and attempts to calculate the heart rate based on the subtle changes it detects. During the measurement, the application shows the current calculation results, and shows the captured data on a line chart. Once completed, the following further details are shown: Standardized values, along with their timestamp (the values are scaled between 0 and 1, and a rolling average is applied for smoothing) Timings where a new heart beat is detected. These data can be shared with other application in order to be exported.

A simple heart rate monitor, using the device's camera to attempt to detect a pulse in your finger.
