+# CPReady
+
+CPReady is an application for the [OpenEarable](https://open-earable.teco.edu).
+It helps the user while performing CPR.
+
+## Features
+- Measures the frequency with which the user is currently performing CPR.
+- Gives feedback according to the current frequency.
+- Gives the user audio or visual support for staying within the recommended frequency range.
+- Optionally supports mouth-to-mouth resuscitation by prompting the user to do so at the recommended times.
+
+## Visual support
+By default, a visual support is shown.
+This visual support consists of an animation that shows an CPR procedure with a frequency of 110 bpm.
+If the audio support is activated, the visual support is deactivated.
+
+## Audio Support
+It is possible to enable audio support.
+For this feature to work, an audio file (.wav format) named "frequency.wav" needs to be on the SD card inserted into the earable.
+This file needs to contain the metronome sound in the desired frequency.
+An exemplary file is provided in the assets folder.
+If the prerequisites are met, the audio support can be enabled with a button while doing CPR.
+
+## Mouth-to-mouth resuscitation
+Optionally, the app can prompt the user to do mouth-to-mouth resuscitation.
+This is done by showing a pop-up dialogue after every 30 pushes.
+
+## Tests
+Since I only have an windows laptop and because of the gradle error, I could not test on an Emulator or physical android device.
+The app is therefore only tested on Edge(Web) and Chrome(Web).
