CSC BLE Bridge
APK
This is an Ant+ to BLE (Bluetooth Low Energy) Bridging app for ANT+ Cycling Speed and Cadence (CSC) sensors and ANT+ heart rate sensors. The app will act as a Cycling speed/cadence and/or HR BLE sensor so other BLE device (phone, PC, Mac, tablet) can reads data from ANT+ sensors.This is an Android app which reads ANT+ cycling speed/cadence (CSC) and/or heart rate sensors in the background (actually in an Android foreground service), and advertises itself as a Bluetooth Low Energy (BLE) device which implements Cycling Speed and Cadence Profile (CSCP) and Heart Rate Profile (HRP) so that other devices can see this Android device as a Cycling Speed and Cadence Bluetooth and/or Heart Rate BLE sensor.This is useful when you only have ANT+ CSC/HR sensors but you want to connect to them as BLE sensors (provided that you don't have an USB ANT+ stick around but happen to have an ANT+ enabled Android device like a Samsung phone).Long hold on the sensors name on top of the screen to rescan for Ant+ devices after the "Start BLE bridging" button has been pressed. All sensors will automatically scan for Ant+ sources when the "Start BLE bridging" button is pressed.

Cloak
APK
A Cloak plugin for Shadowsocks. Cloak is a universal pluggable transport that cryptographically obfuscates proxy traffic as legitimate HTTPS traffic, disguises the proxy server as a normal web server, multiplexes traffic through a fixed amount of TCP connections and provides multi-user usage control. Cloak works fundamentally by masquerading proxy traffic as normal web browsing traffic. This increases the collateral damage to censorship actions and therefore make it very difficult, if not impossible, for censors to selectively block censorship evasion tools and proxy servers without affecting services that the state may also heavily rely on. Details on how Cloak works can be found here. Shadowsocks-android is required, as well as a Cloak-compatible proxy server.
