Requesting feedback on an existing application

Hi, To introduce myself, I'm Harri Pasanen and I'm the developer behind mpaja.com, which a small app development company just starting with iOS applications. One of the applications I've been working on for quite some time is an offline wikipedia reader called Mopedi. Offline meaning that the wikipedia articles are downloaded to your device at installation time and afterwards they can be consulted without network connectivity. I've enabled voiceover for Mopedi and also have a persistent font size setting for the articles, but may miss some obvious improvement, hence this post. There is a free version in app store that contains a curated database of countries of the world, including capitals. https://itunes.apple.com/app/mopedi-world/id578582903 So if you have time to give it a spin, I'd much appreciate feedback. Best Regards, Harri Pasanen http://mpaja.com
