### 5/5 — Amazing

*2026-07-19, version 3.15.1*

This is such a useful tool thank you for making it!

### 5/5 — Appreciate the easy access to specific catalogues

*2026-07-02*

Amazing how volunteers have done so much and made knowledge easier to download based on your needs.

### 1/5 — Lacks discoverability

*2026-06-08, version 3.15.1*

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.

### 5/5 — GOD BLESS YOU!

*2026-06-08, version 3.15.1*

Whoever made this, you are well wished.

### 4/5 — App Icon Not Adaptive

*2026-05-28, version 3.15.1*

The static icon needs an update. It should adapt to user preference for Light Mode, Dark Mode, and Tinted. Please check out the Apple Developer best practices for icons when you get a chance.

### 4/5 — Real dark mode

*2026-05-16, version 3.15.1*

Thank you for this wonderful all. 

Could you change in dark mode the color of  texts in Wikipedia articles from dark to white and also the background from white to dark (exactly as is now possible in the Wikipedia app dark mode for iPhone) making it a REAL dark mode?
Also the catalog can not be updated

Thanks

### 2/5 — Needs a Home Screen!

*2026-05-13, version 3.15.0*

Please make it easier to view all downloaded libraries with a single tap

### 5/5 — Perfect app

*2026-05-02, version 3.14.0*

Worthy of every star.

### 5/5 — All of Wikipedia

*2026-04-04, version 3.13.0*

Allows you to download all of Wikipedia

### 1/5 — How to logout

*2026-03-26*

Never

**Developer response:** To use Kiwix, you don't have to login (or logout) anywhere.
