For Android, I use the "Truth & Life" app, which uses the RSV-CE. It has an audio bible as well, but only for purchase. I didn't buy it, so I cannot speak to the audio quality. Font can be made quite large for those with poor eyesight.

Do you happen to know what translation of the Bible you have? If you don't have one, any modern Catholic one will do as a good first read.
If you don't mind reading on your phone, try this (Android):
