I am often asked by those with older devices how much memory the Gospel Library uses. I have downloaded all of the material in the Gospel Library and taken screenshots to help those concerned with storage; it serve as an approximate guide.
The screenshots are from an iPhone. Currrently, the total for all of the downloads is 1.72 GB. The total storage for the app and the downloads is 2.83 GB. For my Android the total for the app and downloads is 3.06 GB.
As can be seen from the above, the numbers vary according to the device being used. Keep in mind the numbers are approximate and will change in the future.
Because this serves only as a guideline, not all material needs to be shown. For example, you can see that a general conference uses about 1 MB. The titles that have an “*” indicates that it is only the first of many pages.
