I started listening podcast on iPod touch 4th,
Then three years has passed, My iPod touch is a little bit obsolete.
And I hate iTunes because it’s slow to start on windows and has many bugs.
I tried to find the counterpart in Android apps,
After struggling, I finally found good apps.
Podcast Addict has many features,

You can see script (if mp3 file has lyrics),
You can change the speed.
The most favorite thing is to copy downloaded mp3 files to your computer easily without using special software such as iTunes.
