I’m working on mobile application that reads wikipedia articles using IOS Siri voice. It downloads text extract, breaks it to chapters and reads, allowing to skip to the next chapter. 

Siri voice is still quite annoying, but it is getting better every year. This app could be useful for people who want to listen to wikipedia content while on the move: driving or walking , or visually impaired. It is much more convenient than the out-of-the box text to speech feature that allows you to listen to selected text. 

The app allows to search articles by geolocation or by title. See attached screenshots.

I would like to ask for your advice and opinion on a few issues.

1. Are there any license limitations  for wikipedia content that would put restriction on how such app can function ?

2. Do you know if this was tried before? If yes, it probably failed because I don’t see any app of these kind in the app store. Any recommendations how to make it work and reach out to the maximum number of users who may find it useful ?

3. Any features you would recommend that may be useful in such application?

4. Who can help me with the question regarding Wikipedia logo/mobile icon  trademark reuse ? If trademark allows , I would consider replicating Wikipedia mobile app icon with the word “audio” beneath W. 

Any help greatly appreciated!

Thank you,

Dmitry Talisman.
