Раздражает неимоверно. В добавок к этому в той же справке третий уровень иерархии кликом на втором после Collapse all не раскрывается вообще, только через Expand All, что тоже адски неудобно. Писала и про первое, и про второе - за два года исправлений так и не вышло. В общем, поддержка у приложения отвратительная, испорченное не исправляют. ### 3/5 — Precisa consertar a opção de notas *2017-11-23* Quando coloco uma nota não consigo ver as primeiras linhas e nem quando eu as acesso consigo ver oque esta escrito ### 4/5 — ios10になってから変 *2016-09-21* とても具合が良くて 最高だったんですが 注釈のところカーソルが出ない 非常に困る なんとかしてください！ ### 3/5 — Good app *2016-09-18, version 6.8.7* I like this app in that I am able to read the .chm books I have, however some of the functionality needs work. The buttons on the top that are supposed to allow you to bookmark pages etc, are hidden beneath the page and not accessible. With some clean up of function I would give it a higher rating. ### 4/5 — Need more features. *2016-01-17* Excellent app. But frequently crashes while adding document via iTunes app share. Also please introduce export/backup directly to cloud or network drive instead of manual backup via iTunes. ### 3/5 — does it work on a mac *2016-01-05* i have dowloaded the app on my iPad & mac book. but it does not seem to work on my mac. is this app only for a iPad & iPhone??? does this work on a mac book laptop. please help. ### 4/5 — App crash after The last update *2015-11-06, version 6.8.2* Please fix this problem ASAP. I cannot access the app anymore ### 3/5 — 환불 부탁드립니다(would you please refund this app) *2015-11-03* 제가 원하는 기능을 지원하지 않아 환불하려 합니다.(This app doesn't support function that I need. please make refund for this app. Thank you) ### 3/5 — バグ改善して下さい *2015-09-25* 時々マーカーが色が変える事が出来ない 色を変えたりゴミ箱などの表示がほんの一瞬で消えてしまうので色の変更などができません。 バグ改善お願いします ### 2/5 — Вылетает на ipad air *2015-07-13* До этого нормально работала. Сделайте что-нибудь, пожалуйста! Много важных файлов не могу открыть ### 3/5 — ePub reader *2015-05-02* This ePub Reader is working, but when you use a certain link inside a publication then the type size increases very much. This is not acceptable. It seems to be a bug. Your programer should correct this asap. Btw. the price for the App is too high in comparison with IBOOK which is free of charge. ### 5/5 — I like to use this application! *2015-03-16* This application is very useful! ## Most critical reviews (10 lowest-rated) ### 1/5 — Some crushes *2018-10-24* Not searching in whole documents when the book is large ( 5000 page ) like Nelson textbook of pediatric ### 1/5 — Never buy it, there are many ads in premium version *2016-04-29, version 6.8.3* After updating latest version of CHMate Premium, there are many ads in it. It is really terrible and disappointed. ### 1/5 — Disappointed *2015-12-11, version 6.8.2* There is no help. Don't like the way to use annotation. Not worth the money spent ### 1/5 — Crash *2015-10-03* Ne fonctionne pas.... ### 1/5 — アプリが消えた *2015-10-02* アップデートしたら有料版のアプリが無料版になってました。購入済みの中にも有料版はなく、再ダウンロードができると信じて購入を進めたらまた課金されてしまいました。しかも中の資料も復元できませんでした。本当に最悪な気分です。 新たに資料作って作業してますが、かなりバグってます。 気に入って買ったアプリですので、早めの改善をお願いします。 ### 1/5 — 改善要請 *2015-09-23* iOSを9にアップデートしたら、全体的にバグっています。とても使いやすいリーダーですので早く元に戻してください。 ### 1/5 — Не все .chm файлы открывает. *2014-12-06* До последнего обновления работала неплохо. Сейчас перестал открывать некоторые .chm файлы. Не понятно почему. Жаль, была хорошая программа. ### 1/5 — Disappointed *2014-12-01, version 6.5* I restored my backup and I missed my chm files. Your app dont support "open in app" option for chm files. ### 1/5 — Crashes *2014-11-26, version 6.5* I imported a chm file into the app and it's been crashing on startup ever since. ### 1/5 — Глючная программа *2014-11-13* Вроде бы хорошая программа, но очень часто вылетает на этапе загрузки chm файла с почты или с другого приложения. ## Most praised reviews (10 highest-rated) ### 5/5 — Good *2020-07-11* Все хорошо, отображение и чтение. Из минусов, в заголовке не отображает кириллицей названия глав. Разработчики не бросайте приложение! ### 5/5 — Great EPub CHM Reader *2018-04-29* Love this app! ### 5/5 — 최고 *2016-09-11* 더이상 무슨 말이 필요한가 ### 5/5 — CHMate Premium *2016-08-02, version 6.8.5* excellent app ### 5/5 — Love & use this frequently *2016-05-18* I have been using this app for long. Very useful serves the purpose. Doesn't not annoy you to rate it in middle of your reading. Since this app is so useful to me & I admire that it never sends pops up for rating, I put in extra effort to search it in App Store just to express my gratitude to the app creator. Thanks. ### 5/5 — A superb reader for chm & ePub ebooks *2015-10-28* CHMate Premium is the best chm e-book reader at App Store. It allows you not only to highlight but also to annotate a particular portion of texts that may interest you. Also, it allows you to import e-books from iCloud & Dropbox or Desktop web browser. Moreover, it allows you to organize your e-books based on collections. Although it is quite versatile, it is quite easy & smooth to use it. I highly recommend it. ############################## [last review] Better than ever! Now, it can read ePub e-books. ####################### [Old review] Several years ago, I suggested that the developers should have added highlighting & annotation ability in this app. Surprisingly, they did listen, and added these features in a short time. Ever since, I've been comfortable with using CHMate Premium! In a word, CHMate Premium is the best CHM e-book reader on the iOS platform. #################################### [very old review] This is a very nice e-book reader for e-books in chm format. However, it would be perfect if the developer could add new features such as highlighting & annotation in the very near future. ### 5/5 — No question. THE BEST *2015-10-08, version 6.8.2* This app is so fluid and has a nice hierarchical view of the CHM-style navigation. I tried the CHMplus Pro for $3 bucks less but it was really slow to turn pages. The navigation was bad. Multiple taps to open a search. Forget it. I like that I can open files on Dropbox, but I would prefer to see Google Drive integration. Thanks. ### 5/5 — Good apps *2015-10-04, version 6.8.2* Please make it possible to share and open files with other apps and add wifi option for send receive files. ### 5/5 — Хорошая программа *2015-06-09* Хорошая программа, работает стабильно, кириллицу поддерживает везде (по крайней мере для моих файлов; иногда, правда, нужно выбрать кодировку в настройках), но в целом очень достойно и удобно. ### 5/5 — Great app! *2015-05-30, version 6.8* If you need to use chm files, you will be ok with this app. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
