But how do you read the passwords from let's say iOS ? I don't see any iOS client on the website. Thanks.

You need to download an app. Search keepass on ios (I use android so I can't recommend one to you). They won't be made by the same people, but they can use the same password database

You use any Keepass compatible iOS client and access the same file (for example using a WebDAV share)
