Does not fill the screen of the XS Max. Probably will only fill the screen of a 7 at best. (That’s my guess, not a fact) The look of the app is outdated, hence the lack of updates. Good content, could be displayed much better and incorporate the new functions of new models. ### 5/5 — Excellent *2016-12-29* Plenty of information on any country. The rotating globe and being allowed to choose a country is a nice aspect of this wonderful app. Truly a must have app. ### 1/5 — Used to be the best, but long abandoned *2013-04-04, version 4.3.1* Developers have abandoned this app with no major updates or fixes for errors. Nothing more needs to be said. DO NOT DOWNLOAD. Get Wikibot instead. ### 1/5 — A buggy app *2013-03-28, version 4.3.1* Once you save an article, pictures and equations are not displayed anymore. This is a really annoying bug essentially making this app useless. ### 1/5 — Garbage *2013-03-12, version 4.3.1* Doesn't work with iphone 4. Infuriating for a paid app. ### 5/5 — Great app. 4.3.1 broken in iOS 5. *2012-12-07* I love this wiki app, but needs to be fixed to allow iOS 5 again. 4.3 ran fine. Not every is ready or able to upgrade to iOS 6 and it's way too early to make that the minimum version. ### 5/5 — Absolutely the best Wikipedia app. *2012-10-01* This app is a must have for any regular Wikipedia user. saving for offline works perfectly and is a great feature. Everything loads quickly and neatly. It's easy to adjust the viewing. I love this app. I use it every day. ### 5/5 — Great idea having customizable theme *2012-05-23, version 4.0.5* But, could u please fix the bug that color selection wouldn't save probably. Looking forward to see an update! ### 1/5 — Worthless. *2012-03-31, version 4.0.3* Currently completely unusable on my iPhone 4. Do not bother with this app until they fix it. ### 1/5 — Unusable *2012-03-27, version 4.0.3* Great on the iPad but the iPhone version crashes after a few minutes (4S). Once this has happened it crashes again within a second every time the app is restarted. Killing the process doesn't help either. Simply inexcusable for a paid app. ## Frequently asked questions about WorldABC Blue ### What kind of information does this app provide?
