Hi laurel, I've used both Learning Ally and Audible. Here's a short comparison.

The basic Audible membership is $7.49 for the first 3 months, then $14.95 each month after that. This adds up to $157 for the first year and $179 each year after. This membership gives you one book download per month. Any additional audiobooks must be paid for, with most books within the $20-30 range. They are professionally narrated, but not DAISY compatible. They can be played on a computer, Android app, or Apple app.

Learning Ally membership is $119 per year and allows you to download as many audiobooks as you want. They have over 75,000 volunteer-read titles in their library. They are recorded in professional recording studios and checked for quality. In addition to numerous genres of pleasure reading, the library also contains the world�s largest selection of audio textbooks. The audiobooks can be played on a DAISY device, computer, or Apple app.

Hope this helps!
