There are the official 'real books' either printed or digital from Hal Leonard or Sher Music.

Links for their digital here:

You are probably familiar with their printed books (navigate through their sites for information on those.)
Note that their chords may not be the same as the ones in iReal b. There are different versions of the jazz standards and chords can be different in each source you find (this is normal!) because different players and bands can use different chord structures.

If you have an iPad you might find this thread of interest:
