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 (That’s my guess, not a fact) The look of the app is outdated, hence the lack of updates.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. ### 4/5 — Much, much better! *2010-08-26* Well, I rated this app one star awhile back, but I came back to amend because it's been getting better and better. I have a few major gripes with it which is why I've withheld two stars. One is that there is no "stop" button to allow you to stop loading if you mistakenly hit a link. This is especially annoying when I'm on a slow connection where I have to allow a page to load fully so that I can use the back button to get back to where I need to be. If I use the back button while loading, it will take me to the page earlier than the one I just left, so the only way not to have to load two pages would be to have a "stop" button. I find it surprising that such a simple function would be ignored in the first place. Also, I would very much like to see some documentation. No matter how simple the app, there should be a help page. Another thing that bugs me is the browser's (online browser, links outside of Wikipedia) "loading" icon never goes away. It just stops spinning. There should be a different icon and you should be able to refresh the page with that. Not sure that thing was neglected ether but hopefully the devs will care enough to fix this. I think they do given all of the updates they've been giving us lately. Lastly, I wish there was a way to go "back to last link/view" so when I click on an in-page link (on the same page), i can easily get back to the same spot I was just in. It would make it easier to jump to a note and get right back to where you're reading Otherwise, this is a cool and nicely functioning Wikipedia reader. I'm very glad I purchased it, and that is one thing I don't often say about other apps that I've purchased. Also, I felt compelled enough to come back and raise my vote and I will gladly do so again when these features are added. I'd raise my vote even just for the "stop" loading functionality. I'm very happy to see the devs really staying on top of developing this app and adding to it. There was awhile where the app was sort of stagnant.. And the title was changed to "Knowledges", heehee. Glad to see they listened to their users and fixed it right away! Also, I love the new icon!! Four stars, only one to go with those additions! I tend to lower my votes one star at a time if the app never gets updated and fixed after some time, so I've raised it for now and hope to see updates soon! ### 5/5 — Good app! *2010-07-13, version 0* I always use this,very good! ### 5/5 — The Best is Back! *2010-07-10* When Simplepedia was temporarily unavailable from the app store, fearing the worst, I tried the so-called best wiki client of all - the one with the brown icon. It doesn’t really measure up to this fantastic app. Besides finding more relevant articles, one of Simplepedia’s ace features is you can quickly change languages from the search field without having to go to settings. Neat! ### 3/5 — Almost there... *2010-07-02, version 0* Edit: removed 1 star as 3 updates have been released since getting this app and it still crashes every time I load a large image. *** Incredibly attractive app that automatically saves content to view offline, lets you customise the look, makes searches for headings easy. Wikipanion+ might have a couple of extra features, but none that matter to me (find an article, save it, read it in an attractive format, search in page - that's all I want). 'Articles' is in the same league in terms of graphics, but you can't view articles offline and it's a pain to access some features. The reason I haven't given 5 stars is that it crashes when I view large images - not just occasionally, but every time, if the image is large enough. If I'm looking at art or detailed photography, that's a serious problem, and it's meant that I've had to keep other wiki apps on my phone just in case. A way to organise your saved articles into folders would be a bonus too. ### 2/5 — I would love to get beyond opening it *2010-06-26, version 0* Unfortunately I cannot. Every time I open this app and look up the first article, it tries to inform me of the operating features of this app and then it crashes. Really? I'm very envious of all of you who have gotten to use it or still have your $1.99. ### 5/5 — good app *2010-06-12, version 0* It provide notes with offline,great! ### 5/5 — Great app *2010-06-12, version 0* great app! the offline feature is very useful! ### 4/5 — So cool app *2010-06-12, version 0* haha I like it...great app. ### 5/5 — cljgood *2010-06-11, version 0* very good! ## Most critical reviews (10 lowest-rated) ### 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. ### 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. ### 1/5 — crashes after every opening after the update *2012-03-22, version 4.0.3* after the march 21st update it crashes upon every opening. used to be the most solid wiki app up until now. FIX. ### 1/5 — Crash *2012-03-21, version 4.0.3* Crashing all the time after launch. iPhone 3GS, iOS 5.1 ### 1/5 — Used to be good *2012-02-20, version 4.0.2* What a crying shame, it wasn't broke and they tried to fix it. Saving articles for offline is hit and miss. ### 1/5 — Crap *2011-12-22, version 4.0.2* After first search, giant hint overlay about tapping upper or middle or bottom WON'T GO AWAY. So unreadable. Features look meager ANYWAY, despite AppAdvice's INEXPLICABLE "Essential App" recommendation. 99 cents down the drain. ### 1/5 — Worst updat ever *2010-06-17, version 0* I hereby delete "Knowledges" from my iPhone. All the other wiki apps appear better. What a waste!!!!! ## Most praised reviews (10 highest-rated) ### 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. ### 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! ### 5/5 — Please update :( *2012-02-15* I love reading options only aval in this app, however I would love to see more things which are present in other wiki apps. Also some article wouldn't go for offline list. ### 5/5 — 地震后为什么用不了？ *2011-03-29, version 3.3.1* But why Unavailable after the earthquake? ### 5/5 — easy use *2011-02-12, version 3.3.1* this app is great. Read the offline notes are convenient. ### 5/5 — Love.  *2010-08-21, version 0* Like I said. Love it. But I wish there were a home screen so it wouldn't consume time loading the previous search ### 5/5 — 很好，不错 *2010-07-17, version 0* 下了就支持 ### 5/5 — 好用 *2010-07-17, version 0* 很方便，推荐。 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
