A2DP Volume vs Ruler (Privacy Friendly)
Side-by-side comparison of two open source alternatives
A2DP Volume
Automatically adjusts the media volume on connect and resets it on disconnect. This is done so that stereo streaming audio can work properly. Intended primarily for car Bluetooth systems. It can read out text messages using Text To Speech (TTS) services while you are connected. Each paired Bluetooth device or virtual device (home dock, car dock, power connection, or headset plug) can be configured to your liking. There is a manual on the website. A secondary feature is the ability to capture location information so you can find where you left your car. The location can also be automatically captured when exiting Car Mode on your Android device and read by any app that understands GPS data.
Ruler (Privacy Friendly)
Privacy Friendly Ruler can display a ruler or protractor at the edge of the display. This enables on the fly measurements with the smartphone. It belongs to the Privacy Friendly Apps group developed by the research group SECUSO at Karlsruhe Institute of Technology. More information can be found an secuso.org/pfa/ What makes Privacy Friendly Ruler different from other similar apps? 1. No permissions Privacy Friendly Ruler does not require any permissions. 2. No advertisement Many other free apps in the Google Play Store dazzle annoying advertising and also shortens battery life.
