I bought Yuntab Bluetooth Smart Jogging Watch U8 from Amazon. The printed directions say to download an APK from an IP address with FTP:
thufir@doge:~/.bluetooth$ thufir@doge:~/.bluetooth$ ftp 188.8.131.52 Connected to 184.108.40.206. 220 (vsFTPd 3.0.2) Name (220.127.116.11:thufir): anonymous 331 Please specify the password. Password: 530 Login incorrect. Login failed. ftp> exit 221 Goodbye. thufir@doge:~/.bluetooth$
The directions don't specify a user or password.
How do I get the app?
