Still a lot of bugs. Do not use it if you are not a developer.
- no need to install the apk on your phone. enable USB debug mode, and plug in.
- Save your contants to whatever text format, utf-8 recommended.
- Config and run the python script. Use python 2.
PS: develop paused. My school managed to make our winter vacation shorter by bypassing laws & rules. No more time to develop.
