5 stars: Thank you for fixing the issue with your last update. Now all works, no crashing during the run. Wonderful software. Please for next time accept all thru details thru regular a email or Google crash feedback. I have no reason to register on GitHub or any other many very specific tech site's just for providing tech details. Thanks again.
4 stars: This app is a perfect minimal interface for offline knowledge. On a 128GB or more storage device it is perfect for exploring somewhat curated knowledge and gaining information without networking. #1 app for disaster recovery knowledge. One con that could be improved upon would be more wikis and forums as well as the ability to search both more content to download and to search through downloaded content better.
5 stars: Love having wikipedia offline for when I am away from WiFi for extended periods of time. This app works great and has many more packages to download besides just wikipedia. (even videos)
5 stars: Works fantastic offline. Only issue is on cell phone scrolling pinching screen to read content. Only used the 3.7 GB buy pix included. Also recommend the Medical Wiki for research anything in human body diseases etc. Can't wait to get updated versions. Still using 2010!
3 stars: Doesn't download books in background or while screen is locked. Works fine though once you manage to download something.
3 stars: DESPERATELY needs the ability to UPDATE existing libraries. Seems the only way to update them...
