MyAppsList by Boots quickly generates a list of all the third-party apps on your EVO, including barcodes and direct links to Android Market if you want them, and spits it out in your choice of vB code (for forums), plain text (for email, notes, etc.), or HTML (for websites). You can also choose to have the list saved to your SD card or copied to the clipboard so that you can paste it somewhere later.
In addition to all the app info, MyAppsList also churns out a little summary with the name of your device (the EVO is known as the HTC PC36100), the Android version, build number (even custom ROMs are identified here), and the total number of apps installed.
MyAppsList is apparently still in beta, but I haven't encountered any problems on my PC36100 running Android 2.2, build FRF91.
