The issue I had was my podcast programs provided the transcription on their website. This can present an inconvenience on a smart phone while riding the bus.
I found this Android app that can play a downloaded podcast and its transcription at the same time. It syncs up very well. After you download the podcast, you copy and paste the transcription in a text file (.txt). The podcast and the transcription MUST have the same name and be in the same folder. For example, iTalki_Is_Great.mp3 and iTalki_Is_Great.txt.

The app is free and has no ads. Hope this helps somebody. You can also use this as your own karaoke system and sing along your favorite songs.
Well, there's an Android app called WorkAudioBook. It works with mp3 + subtitles in either .srt format or WorkAudioBook's own format. Both audio and text are kept in sync. Give it a shot:
I'm starting a blog with short stories in easy Spanish. I'm adding both mp3 and subtitles in both srt and WorkAudioBook format, so you can have both in sync on your device:
