Ping

PingMeter is a simple graphical interface to PING command, a network diagnostic tool, with useful and fun SOUND effects.

RUN IN BACKGROUND: You can leave Ping run and switch to other apps, e.g. another network diagnostic tool (for example to see WiFi signal strength). Meanwhile you can hear the PingMeter sound effects to always knows what is happening.
Use case: you can check and test the WiFi coverage on a big room without staring at the screen. Every lost packet will be immediately identified by sound. NO MORE NEED TO CHECK icmp_seq NUMBER ONE BY ONE!

While ping is running you can see the PING WEATHER on the top right. It suggests you the number of packets lost. e.g. a clear sun indicates 0 packets lost, storm indicates no good network connection.

Tested on HTC Desire 2.2 (no root), Nexus S stock, CM7, CM9.

NOTE: PingMeter depends on ping command on your phone, this must be executable to allow PingMeter to run. Usually there is no problem, no user action is required, but some vendor (or Android release) could disable ping to normal user (non-root). This is not due to PingMeter and it can't resolve the limitation, sorry.
