  1. Karel Bergmann-avatar

    great but on opening the app it won't open the book you're reading and you have to find the book. should be an easy fix for them. They just changed their fotmat. Took away the goodies and now it stinks. I'll be looking for something better. Product should be improving not worsening.

  2. Trisja Weiss-avatar

    This app was great! After the latest update however, it doesn't keep my bookmark and open up on it when going into the book as well as my folders that i created are no longer easily accessible. Overall not happy with this update and wish i could return to my previous version.

  3. Marielle Chevrier-avatar

    Marielle Chevrier


    Great book reader for my local pdf files. Would be nice if it let me read docx files without need to buy subscription. I'd be willing to pay $ (not monthly subscription) to read local docx files. (As requested, I changed my rating from 4 to 5. Thank you for passing my request to the developers.)

  4. Ahmed Isti-avatar

    This used to be my favourite app! Recent version won't let me import any pdf books (unlike the old ones) and application crashes on any attempt to import books, totally unacceptable! Please fix and I'll rate it five stars!

  5. Sari Stein-avatar

    New version broke the app - buggy, doesn't remember my place on restart, and filled with ads that cover the text. The new fonts are harder to read, too. Please allow rollback to the previous version until you've fixed this.

  6. Jill Fernandez Pajulas-avatar

    Jill Fernandez Pajulas


    the reason why ive downloaded ang used this reader for years is because u can costumize everything from margins, fonts, backgrounds...but what happened?? you removed many options....planning on downloading another reader

  7. Keisha Lyte-avatar

    I would love to know how my books that I had separated into collections by author are now all mixed up. What's going on with this app? I use to love it

  8. sajad borhani-avatar

    I enjoyed your app but I am not an english person hence reading this book is a little difficult, It would be very hood if there were a dictionary in app so i could understand the meaning of new word's thank you

  9. Hishan Rand-avatar

    In the past,I could hold a word and then I could take the meaning of the word by joining to oxford dictionary.But after this update I cannot do it.what is the reason for that

  10. Annа Boeva-avatar

    Can you please remove the bar that always shows at the bottom, it's so distracting!!!

  11. Spate Davis-avatar

    After the latest update the developers removed the awesome option of different types of pages it made the app worst

  12. Ariana Amador-avatar

    It used to be my favorite but since the latest updates it doesn't keep my bookmark open

  13. jason desmond-avatar

    I'm sad that I've lost 10 minutes from my life downloading this app , I searched for more then 20 books and novels I found non of them

  14. Deep Aman-avatar

    Such a wonderful app for book lovers .I really enjoying reading books and I developed a habbit of reading books through this app One thing I want to suggest that there must be a tag option so that whenever we don't understand the meaning of any word we can search its meaning on Google and tagged it with that word, so that next time don't need to Google that word again. Amazing app.

  15. khadidja khadouj-avatar

    khadidja khadouj


    It's a great app , but I have a problem I can't read offline books , because I'm student , and I only have an hour of reading books every morning when I take my bus , since we are quarantined it's ok but I hope you fix this problem at least my library

  16. Cindy Carvalho-avatar

    I did love this app. I plan on loving it again after they give us the ability to highlight and bookmark again. Until then, I'm shopping around for another app. P.s. Well how long do you think that will take? It's been a couple of months! It's May and this has still not been resolved.

  17. Sudhir Kumar-avatar

    I used to love this app so much. It had a great selection and variety of books. Books were available a day after their international release. But after the last update I am not able to download the books that were previously available and the range of books currently available is bad. Hopefully you guys can revert back and increase availability of books.

  18. Jayme Lawrence-avatar

    Was generally happy with this app except for the occasional bugginess. Purchased the premium version years ago. Recently, the splash screen promoting the subscription service began appearing. No big deal, I can navigate around that. However I'm now seeing ads when viewing my library of LOCAL content as well as ads while I am reading my own LOCAL books. If I'm going to be forced to see ads for a service I already paid for then I might as find another reader.

  19. Mahdi Gholami-avatar

    I used to really like this app. However, after updates some feautres are gone. For example, we could use the highlight function before, but now there's no such a thing and even writing a note.

  20. Bolla Rice-avatar

    I already paid for this app now I get an ad for the subscription every time I open the app. I'm never getting the subscription, how do I stop it? I already paid to remove ads. Edit - your answer below makes it clear you aren't paying attention. I paid to not have ads on the app. Every time I open it's or open a new book, I'm blocked by your ad for a new subscription service I do not want. Remove it or allow a "don't ask again" box. I literally paid to not have to look at ads, including your ad

  21. Masked Crab-avatar

    The app was wonderful and amazing last year the greatest app there was with amazing books from any one and everyone uploaded every day but now a lot of the book that were there last year are gone. Deleted and left only older book by good authors but are very old and not always attractive to younger audiences. The app was great but now it is hard to find a good book or the continuation of a series which you were reading before. Like I was reading the throne of glass and now its deleted. It is sad

  22. Jonardon Borah-avatar

    I guess this app wants to milk existing paid users by making them pay monthly. This app was a lot better and user friendly when it was a simple and useful ebook reader. Now it has lost its charm in the pursuit of monthly income by subscription. What a shame.

  23. Jelbrehir-avatar

    I really like this app. It's very user-friendly. My one problem is that I bought the Pro version to get rid of ads, but now I keep getting a message about "upgrading" to the monthly-fee version. I already paid for the pro version, there is no way I will pay monthly to get rid of ads that I already paid to get rid of.

  24. felix wekesa-avatar

    Not better than the last app. Very bored why this app can't import very many books...?! I used the last app UBREADER and it was good to import many books , and I could important over 5000 Books I wonder why it doesn't do so. Please improve this side...

  25. Uke-Aameh Winifred .F.-avatar

    Uke-Aameh Winifred .F.


    I have loads of book apps, but this is definitely my favorite. I can change the background, increase brightness, increase font, and do somuch more, this app makes not reading from paperback not so bad and they can publish your books too!

  26. Hanny Steiner-avatar

    As for your reply, I did contact your support, no help there!!This is a scam!!! They will charge you 30$ automatically and illegally, just for installing the app, claiming you didn't cancel after free trial, though you never agreed for it nor created an acount. Moreover, it will automatically create a recurring anual subscription for you, even if you didn't provide any details. They use your Google play account for charging. I never experienced such a scam before. Be ware not to fall as I did!

  27. Rajeev Singh-avatar

    I had purchased the premium version of the app for 332.83 Rs what happened to that version. Now it is free to install but i will have to pay monthly. What about my money! Worst development! I have no option otherwise I have given it not even a single star. Worst Experience ever!

  28. ShadowIsatis-avatar

    While I'm happy with the app as it let's ne read my epub files, I am utterly sick and tired of it constantly offering a yearly subscription upgrade every time I open it. Can't you guys program in a 'do not ask again' option?

  29. David Todorov-avatar

    Used to be amazing, I bought the product for 4.99 way back when you could upload your own ebooks. I used it for its text to speech, so I can enjoy my ebooks on my long commute. The function that I purchased this app for is no longer available. Very dishonest practices

  30. Christina Reuter Mitchell-avatar

    Christina Reuter Mitchell


    VERY DISHONEST DEVELOPER-Vendor of Media365! Media365 was called UB Reader. The ad-free full version of UB Reader Pro cost $4.99. It was great until the developer changed the name to Media365 ... and killed all the premium full licenses! Now, the new MEDIA365 reader is ad-infested as a Free version and a MONTHLY $3 subscription for the FULL version. EVENTUALLY, Greed always wins over Integrity! Do NOT trust this developer. NOTE: The actual developer is MobiSystems produced the best Office Suite app in the early days of Android. Office Suite became grossly overpriced ... and Microsoft finally produced good Office android apps for Word & Excel. YOU ARE WELL ADVISED TO AVOID MobiSystem apps ... they have become a total rip-off.

  31. Mr. Fahrenheit-avatar

    well i didint pay for the premium so i don't have problems just one there is a feature in manga apps that you can flip page just by touching the right side of the phone i wish had these feature in this app even though it's a great app

  32. xerotonin cake-avatar

    The highlight tool would be of very much help. I personally like to highlight some words and it's hard without that tool. Please bring it back

  33. James Ndumia-avatar

    This used to be the best reader for my books. However, The new version are devoid of the highlighter and bookmaker.These used to be the best parts of the App

  34. Melikeygama 21-avatar

    It pretty good but missing alot of good books and when I sign in with google account to go premium, it says "not logged in into google account" or "couldnt connect to google account".

  35. Julie Paradise-avatar

    I absolutely love this app. However, I also love widgets and I receive repeated errors when I attempted to add the widget to my home screen. (Note 9) Perhaps it's an isolated issue though. Otherwise, a truly great app!

  36. Mohammed Saqer-avatar

    It is a very good application ,but the only problem is lack of ability to put highlights, underlines and taking notes

  37. Sivakumar Gudapati Joshua-avatar

    Sivakumar Gudapati Joshua


    It is more than a book experience because of the extra features in reading. Very good app. Strongly recommend it.

  38. Dave Aspden-avatar

    I have been using this app for a long time and was happy enough to purchase it to be ad free. Now every time I open it up there is a full advert wanting me to subscribe to the same app I paid to be ad free. Not impressed. I understand it is optional to subscribe, but I already paid once to be ad free and it is not acceptable to now force this ad. 2 stars because it's a good reader, otherwise it would be one star.

  39. Cody Heath-avatar

    Love this app as it is the easiest way to read epub files from local storage. With that said these ads for the subscription service have been getting very pushy. I have been using this app since it was called ub reader. I think I even bought the premium version back then but I can't rember. It would be very nice if more fonts were available but I do not know if that is the app side or the epub file side.

  40. felicia w.-avatar

    This app is good. But I hope I could back up all of my data (the bookmarks, highlights, and notes). Everytime I got a new phone I lost all of those 😓

  41. King Zizou-avatar

    Rated this app 2 stars a while back and then stopped using it. Decided to give it a chance again and I'm glad to see how much it's improved and love how they actually listen to everyone's complaints. Great job on a great app

  42. Amarula Al-avatar

    Unimpressed. Bought this app years ago because it was good and I didn't want to see ads - but now Mediafire has ads all over the place (regardless that I bought it) and the app has also become less reader-friendly.

  43. Chamara Mohottiarachchi-avatar

    Chamara Mohottiarachchi


    i have used this app a lot. but after recent updates it keeps going blank. cant open any book. hope this will be fixes soon

  44. anzela ghimire-avatar

    I really like the app. You guys can make it better by including books from more authors.

  45. Sadek 2011111-avatar

    It's really a good app , however ; im not able to move from one page to another when it's magnified . I have to resize it back to normal in order to move . This is really bothering me , Plz fix it to receive 5 🌟 . P.s. I changed my rating now to 5 after your answer . Yes pdf cant be resized , rather extensions like epub and others can be .

  46. A-avatar

    Very good reader bought the app and now 6 months down the road trying to sell a subscription to remove ads. Can't say I've ever noticed ads when reading except the one pestering me to buy a subscription. How can a buyer be expected to trust a company that invalidates a sale to sell the same product back to you again.

  47. Dr. S S-avatar

    Good app as we can also publish our own book but there are not too much books in it. The book I was finding didn't appear, please add some more Books.

  48. Nina R-avatar

    awesome get to have my books there no other app lets your books get sent over there great i love it !!!! Ok first just changed my phone and now i lost all my books i love to read now i can not read none of them only one book came back ,? Like what the heck am not happy it is bullcrap thank u very much they should all be coming back not just one maybe i should find a different app? If am going keep having this problem !!!

    I wish there was a nightmode to adjust the brightness because I usually read at night and it really hurts the eyes.

  50. Zarine Arya-avatar

    It's supposed to have a free version, but it keeps pushing the paid version in your face :( .. and an expensive one, at that :( I uninstalled it :(

  51. Ged Reilly-avatar

    Was the best but now, with the ad banner across the bottom of the page you are reading, it is now the worst!!!! Am looking for a new reader app and deleting this. Thanks for the next day response. The ad banner has now gone! Back to 5 stars

  52. Tahmi-avatar

    It'd be better if we could read books free offline without having to subscribe.

  53. Jennifer Floyd-avatar

    Love this app so much! Not to mention the price is right! I read 30.00 worth of books in month! 😊😊😊

  54. Kostas KostasKostas-avatar

    Kimber Holbrooks


    Went to find a specific genra and none were available I love reading books about werewolves but not a single book could be found seems you would have something for everyone very disappointing. Uninstalling oh and if you are reading reviews before you install be carefull and do not hit the get started button at the beginning it will charge you x out and skip it for free reading

  56. Ken Yakiwchuk-avatar

    Terrible business practices! I had previously purchased a license to be ad-free. Fine. No problem. Now, I'm expected to buck up for a subscription? For what I have already paid for? No way! You got my money once, you won't get it ever again.

  57. vaughan edgar-avatar

    Excellent reader. Only occasionally loses place or crashes. However despite the promise of local books being free from ads with a purchase. Every time the app is opened it displays an ad for the new sub service, maybe it should just display when accessing the store.

  58. Ohene Nkatabo-avatar

    This apps has been good to me.It has helped me to download many ebooks.I have a miniature library on my phone where I read books during my leisure time.

    Not helpful in opening .pub documents. Requires you to do a free trial and input cc info to open them and even then, it took several tries to get the doc to inport... and then it's nearly impossible to access your settings to delete the account.

    It used to be my favorite app gor a long time although I am not a premium user.I even recommended this app to my friends but I think something happened, I couldn't find any books of Cassandra Clare, J. K rowling or any other authors as well as other books that I want to read😢

  64. Maica Macaraig-avatar

    I love the app, but for some reason the highlight/note features were not available in my phone, unlike on the phone of my friend that recommended this app. Note that we have the same model of phone. Might be deleting the app soon.

  65. Paul Earnshaw-avatar

    Can't seem to make highlights anymore or bookmark pages since I updated.

  66. Matey Mateev-avatar

    Excellent app. There are many interesting books in the library. I would recommend it to anybody, who likes reading.

  67. J Owner-avatar

    10 minutes and uninstalled. Had a downloaded mobi book in my downloads folder, will not allow uploading. Waste of everyone's time.

    Xochitl Valverde


    Signed up for 7 day trial. Cancel at 7 day still was charged me 29.99. No phone to call just email. Who ever is in charge of emails clearly has no idea for customer care. Although, I send my screenshot of the cancelation, she was reluctant to say "if I had cancel within the 7 days, they wouldn't of charge me. A picture is worth more than 1000 words. I guess not when they have an agenda to commit FRAUD to take your money.

    Stop asking me to upgrade to a monthly subscription. I paid for the pro version already. This is ridiculous. I'm going to find a different app.

  72. Debayan Sinha-avatar

    I love reading. But, I couldn't found any better app like this. Its convienient and easy to use. And you can put bookmarks. So thats an add on to any reading app.
