Update to my review - JR now my first choice for all books

Justread is now my place for ‘casual’ PDF reading as well as EPUB. It’s not LiquidText or MarginNote but for the first time, I have all my ‘reading’ books in 1 place and 1 app. Annotations are a breeze and easily exported to Craft. Moreover, if necessary I can go back to the book to look at my highlights in context. No more scrambling around for the latest ‘definitive’ annotated version.

And - the improvements/enhancements keep coming - I’m impressed

Thank you very much for the review and the title (about successor) you wrote. It says it all. Because that was my aim in the first place, as a Marvin user. And looks like I am going the right way. Have a nice day, PJ.

Amazing and Feedback is heard!

I just recently got this app specifically for changing my font out (I noticed I read better using a bionic reading (similar) font, but it wasn’t working with this app initially. I was bummed initially because it’s a great app so I reached out with the send feedback via email and they quickly responded and resolved my issue, and let me know it will come out in the next update they’re pushing! I am STOKED especially because their are many features that the Apple Books app doesn’t have like reading stats, changing reading layouts, reading voice assistance, and the assistant has functionality for asking book related questions! There’s even a tab where you can vote on feedback given and if a feature should be added, and they let you know when they’re working on a feature in that tab too! It’s very well made and I’m so happy I found it especially as I can organize by series too. 10/10

Response from developer

Hello and thank you so much for this nice and detailed review. We are glad we sorted out the bionic reading font for you. Feedback is something we care about really deeply, which is exactly why this roadmap/voting tab exists. And it's great to hear you like it. If you'll ever run into anything else, you know where to find us :-) Happy reading!

Great app, absurd prices

I like the app and the 20-20-20 reminders, but I don't like that since the free trial ended, I get a popup to pay which I cannot remove to check my book progress.

Response from developer

Hi Moon, thank you for the review, and we're really happy you like the app and the reminders. The app comes with a 14-day free trial so you can try every feature before deciding. After that, a subscription is needed to keep using it. This lets us keep developing the app without ads or selling your data. Your progress is safely saved, so if you subscribe (or buy lifetime), everything will be right where you left it.

É bom mas depois tem que pagar

Acho que é o melhor aplicativo que encontrei até agora mas o fato de precisar pagar pra continuar usufruindo é bem desanimador

Response from developer

Olá! Muito obrigado pelo carinho, ficamos felizes que você goste tanto do app! A assinatura é o que nos permite manter o app sem anúncios e sempre melhorando.

Made me enjoy reading again

I'm pretty sure I've tried every epub reader in the App Store, and this is the only one that manages to provide tons of customization while still looking nice and being easy to use. The app is fast, handles an iCloud folder full of epubs with no issues, syncs book progress instantly between my iPhone and iPad, and is in active development. The reading statistics screen is also super fun to look at.

I came from 18 years of using the Kindle app and watching it get worse and worse with every update. This app shows it's still possible to make a good ebook reader if you actually care about your product. I'm buying a lifetime subscription.

Response from developer

Oh, my. Reading this made our day! As a developer (and a reader first and foremost), there is nothing better than reading that the app made someone enjoy reading again. This is exactly why my son Jachym and I buitd it. Thank you for giving it a chance after 18 years with Kindle, and for supporting us with the lifetime subscription. We’ll keep working hard to deserve it! P.S.:Mac version in the making.

Absurd price but good app

$80 for a lifetime subscription is ridiculous. This app seems great but be serious. That’s the same price as buying a AAA video game.

Response from developer

Hi Bob, thank you for the honest review, and great comparison. The difference is time: most AAA games are finished in a few dozen hours, while Lifetime is meant to be your reader for years. Every future update is included, there are no ads and no tracking, and Family Sharing gives it to up to five family members at no extra cost. If $80 up front is too much, Yearly is $29.99, and the 14-day free trial lets you try everything before paying. Glad you like the app :-)

Just(My)Read

I’m adding this after getting my hands on the 5.2 update released today. I love the updated look, but honestly the constant stream of tweaks and fixes and features is the thing I’m loving most about a really great reading app. The level of support is something I’ve *never* experienced before - between that and all of the customization options it feels almost like this is an app being made just for me.

日本語対応の中では良さそうだけど…

iPad mini 7で使用

▶︎良いところ
・日本語対応している、2026年10月現在の既存のPDF,EPUB書籍リーダーの中では一番良さそう
・読書記録もある
・デザインがモダン
・ダウンロードから14日間は無料ですべての機能が使えること

▶︎気になったところ
・書籍一覧メニューのリストの1項目が横に長いのに、タップが反応するのは文字のあるあたりだけ
・書籍一覧メニューが横幅がかなり余っているのに、縦一列でしか表示されない。書籍アイコンが並んだような画面も欲しい。切り替えても縦一列に並ぶだけ。iPad miniの横幅の問題かもしれないが、画面を横向きにしても同様。シリーズがある場合は横に並ぶためなのかもしれないが、手持ちのデータの書籍はシリーズものがないので、ライブラリが見づらいものになる。
・書籍内写真が下部に出るのは不要に感じる
・書籍内画像がネガポジ反転している?(バグ?)
・価格が高過ぎる。上記のバグや開発途上のところがありそうなのに、7000円代は高すぎる。インディアプリの応援の課金ですら、高くても5000円以内。よっぽど大手で評価もユーザーも多くて安定しているアプリならギリギリ7000円払えるけど、という感覚。14日でこの価格を払うかどうかジャッジするのは難しいと思う。せめて1ヶ月は必要。でも個人的には今の状況でこの価格は払えないなと思った。

Excellent. 10/10!

This is simply the best e-book reader available - by a huge margin! Comprehensive reading statistics and deep Integration with Calibre are my favourite features. This is the most feature rich ebook app available- and I have tried them all. I downloaded the trial (14 days) and within 2 days purchased a yearly subscription, and deleted all my other ebook readers. It’s simply the best. I have no idea why it’s not #1 in the App Store for its category.

Hello Harry and thank you for the review. Hopefully, one day it will be #1. Have a nice day :-) PJ & JJ

3 apps in 1- Five stars

Five stars,
I left a 5* review when this app was first released, but that never seemed to make it to the store. The app can now work with books, audiobooks and comics. I have the app on: an iPad with comics on it, an iPad mini with epubs, and iPhone with audiobooks. Absolutely fantastic.

Response from developer

Hello Richard and thank you for those 5 stars! And you can expect the MAC version in the near future to manage your library the simplest possible way. Thank you and happy reading. PJ & JJ

Your Books, Your Way

I’ve been reading with KyBook3 forever but was getting increasingly worried about the fact that it hadn’t received any updates in years. I bought the lifetime subscription as soon as the free trial ran out, and had just been waiting for iOS 27 to officially release so Apple would let me leave this review.

I’ll start with my one little complaint. Just one. The all-lowercase name justread makes a little spot at the back of my brain twitch. This is an app for *readers* and I can’t be the only one. JustRead, justRead, justREAD. Please?

Other that, the app is great - ridiculously customizable, works great with both my Calibre library and ODPS, syncs across devices, and the stats tab (especially the end of month summary) is very cool. Even supports audiobooks. Best of all, the developer has been *AMAZINGLY* responsive. There have been three updates adding new features and fixes (including two things I’d requested) in as many weeks. It actually has a roadmap tab to show what’s coming next (if you want to see it - did I mention how customizable the app is?).

If you’re an iOS reader, especially one that likes to maintain your own library, this is your app.

(Edit - did I mention how responsive the developer is? My one silly little complaint has been addressed in today’s update. JustRead it is.)

Better than any other!

This app is the best ebook reader out there. Better than kybook3 even!

Response from developer

Hello and thanks for a quick and nice review!

Finally a worthy successor to Marvin

The app fully deserves my 5* score - not only on its existing features, but also on what is promised. Peter’s track record of improvements and enhancements is impressive and continuing. A reading app should fulfil 3 basic functions
1. A good reading experience with easy access to the look & feel of the words on the page. This is combined with control of brightness of the screen for bedtime reading
2. Adroit use of metadata to organise your library - a big tick on this
3. Synchronisation back & forth to your choice of the one true data set of your books - in my case Calibre

In the short time since I found this app and paid the full price (I hate subs), the author has improved it by leaps & bounds. He has even implemented a couple of my suggestions.
Support is wonderful - fast & helpful - bugs (aka features that do not work in the way you expect) are explained & sorted

There is also a growing list of features that are present/fixed/to be fixed/or on the list to do. You can add to this list your favourite wish - I presume that if this is sensible/has support then it will bubble up to the top of improvements.

Disclaimer - I only use this app for my ePubs, and can’t comment as to comics or PDFs

Forget the other e-reader apps - this is the one to go for

Wow great app, awesome dev

I have been trialing this app after having tried a great number of different iOS reader apps. I was very pleased with the features on this app. And when two features I missed from KOReader were missing I made a recommendation that they be added and within the week they were!

Response from developer

Hello and thank you for a kind review. I am glad you are glad :-) And whenever you'll have another idea, please let us know. Happy reading. P.S.: MAC version is in the development and there will be one surprise for Kobo users as I am a big fan and user of Kobo ereaders.

Best e-reader app

Literally the most useful and up to date app I’ve seen. VERY satisfied

Hello Bogdan, thank You very much for a short and nice review. VERY thank YOU :-)

Response from developer

Thank you very much for this long review, and for sticking with the app since the trial. It means a lot coming from a longtime KyBook3 reader! I know how hard it is to trust a new app with a library you have spent years building. I'm really pleased with the customization feedback. Also the end-of-month summary is one of my favorite parts too. And thank you for the feature requests. A lot of what's on the roadmap came from readers like you, so please keep them coming. As for the name: fair point, and you're not the only one who's mentioned it. I've added it to my list to think about (not the roadmap). No promises yet, but your brain twitch has been officially noted. Happy reading!

Finally! I can use my library the way I want to

I have been waiting for years for an app like this, and I've tested too many to count. JustRead has allowed me to make sense of my library, to find what I'm looking for, to read it on any of my devices, and customize it to my preference. I would give it 10 stars if I could. Well, maybe 9.5 stars because there are occasional glitches--but the developer is very responsive.

THANK YOU. Really thanks. Nice to hear :-). Happy reading.

Leider ziemlich gut

Diese App ist eine besondere Lese App. Sie kann neben viele Buchformaten auch Hörbücher, aber das lasse ich hier aussen vor, weil es mich nicht interessiert.
Interessant hingegen finde ich die Möglichkeit, mit Calibre zu synchronisieren. Also starte ich mit dem Sync: Über 4000 Bücher, 100 teils sehr große PDFs: Eine gute halbe Stunde hat es gedauert, ohne Fehler. Wow, das hätte ich nicht erwartet. Das Zusammenspiel mit Calibre ist großartig.
Es gibt viele Extras wie "Lesefortschritt" oder andere Statistiken. Das brauche ich nicht. Wie schön, dass ich das alles von der Benutzerfläche ausblenden kann.
Das Menü steht erfreulicherweise auch auf Deutsch zur Verfügung, da fühlt man sich zu Hause.
Wichtig: Die Formatierungsmöglichkeit der Epubs. Sehr umfassend und übersichtlich präsentiert. Wenn man die entsprechende Einstellung erst einmal findet, kann man auch jedes Buch einzeln formatieren. Eigene Schriften können problemlos importiert werden!
[OBSOLET! DIESES PROBLEM WURDE WIE ANGEKÜNDIGT VOM ENTWICKLER MIT V4.6 BESEITIGT: Für mich ein Negativpunkt: Wählt man den Verlagsstil (Formatierung und Typographie des Buches werden übernommen) muss man ohne Silbentrennung auskommen. Sie ist dann nicht mehr auswählbar. Das ist im Deutschen mit seinen sehr langen Wörter durchaus nachteilig. Schade, ich hätte gern öfter den Verlagsstil genutzt!?]
Ansonsten nur Lob. Die App läuft sehr flüsssig, ohne Fehl und Tadel.
Leider ist der Preis entsprechend. Ein Abo kommt für mich nicht in Frage und die hohe Einmalzahlung ist eine Wette auf die nächsten drei, vier Jahre. Ich habe noch 10 Tage Zeit zu überlegen. Leider ist die App schon ziemlich gut, das Beste, was ich in diesem Bereich getestet habe. Deshalb alle Sterne.

Vielen Dank für die ausführliche und freundliche Bewertung! Gute Nachricht zu Ihrem Kritikpunkt: Die Silbentrennung im Verlagsstil ist fertig und kommt mit Version 4.6. Viel Freude beim Lesen!
