This website literally allows you to download the entirety of human knowledge accumulated over decades and store it locally on your device. this has got to be hands-down. The most useful app of all time.

Appreciate the easy access to specific catalogues

Lacks discoverability

Ironically, users of this offline knowledge library are left needing a built-in ZIM help file to locate, access, navigate, and manage downloaded ZIM files. Until this changes, asking users to donate feels premature.

Update in response to the developers question as to what difficulty do I face? The difficulties have been adequately described and are self-evident on iPad.
