### 3/5 — Corrections à apporter

*2026-06-21*

Les livres et les documents qu’on rajoutent manuellement ne se synchronisent pas d’une application à l’autre (téléphone + tablette par exemple). Le même problème se produit lorsqu’on télécharge un extrait d’un livre d’un catalogue d’une bibliothèque. De plus, les livres sur l’application se retrouvent dans notre dossier document sur notre téléphone; si nous avons le malheur de cliquer dessus, cela les effacent à la fois dans notre téléphone et dans l’application. Sinon le reste va bien.

### 4/5 — Really good reading app but has a minor issue

*2026-05-06*

Loving the app so far, but it just has one issue I’m facing. Sometimes swiping right would end up skipping past the entire chapter instead of a single page. Then I have to go back to where I left off manually. 
Could we have more fonts as well ? Thank you!

### 4/5 — Translation not functioning

*2026-02-26*

I use Cantook to borrow and read books in french. Lately, I have been having issues with the Reverso translation apo not functioning.  Anyone else?

### 2/5 — Ne fonctionne pas avec les livres achetés

*2026-02-14*

C’est dommage ajouter les livres achetés format epub/drm ne fonctionne pas du tout. J’ai cherché à comprendre mais j’ai rien trouvé.

### 4/5 — Fantastic calibre integration

*2025-11-20*

I use this as a daily driver for mobi and epub format, as well as the odd pdf. 

I am able to access a catalog of books hosted on a calibre-web docker container, downloads are simple and flawless from within the app. 

It loses a star for not being able to lock orientation in spite of the host OS. When this app rotates it sometimes skips ahead pages and pages. 

Also the font size and justification settings could use some tweaking. I’d like to choose a stable pixel size or number rather than toggle larger and smaller again and again. Could we also play with margin size? 

Would I recommend? Absolutely. It does the job and I’d gift this to family who enjoy carrying a library in their pocket. 

Kudos to the author!

### 2/5 — Doesn’t support komga with SSO

*2025-04-21, version 1.12.3*

Unfortunately this app is unusable simply because it does not integrate with komga instances that use SSO. I think komga tries to create a pop up for auth and this app can’t handle that

It’s a real shame because every step up until then was smooth and easy, this was looking to be the best ebook app I’d seen so far! If they can fix this, I think maybe I’ve found the app for me. Hopefully it’s a simple fix?

### 3/5 — Pas d’option

*2025-03-07*

Les characteres ne sont pas ajustables et on ne peut mettre le mode dark.  Ce qui est dommage

**Developer response:** Bonjour, vous pouvez normalement modifier les polices de caractère et/ou la taille du texte dans les réglages accessible lorsque vous êtes dans un livre.

Le mode sombre est aussi accessible dans la même section: le bouton "Aa" affiché en haut de l'écran lorsque vous êtes en mode lecture. Le thème général de l'application peut aussi être changé dans les réglages principaux de l'application.

### 2/5 — Notes? Highlighting?

*2025-02-23*

Perhaps I’m missing something, but it’s driving me insane. I was forced to download this app to read an academic text securely. When I’m reading to retain information from an ebook, I NEED to at the very least highlight and bookmark things. Making notes would be better. I can’t even highlight text in this app. It’s awful. So I guess good job providing an app that lets you read? But I need more than that.

### 3/5 — format des polices ne changent pas

*2025-01-24*

au moment d’écrire ces lignes, si je veux agrandir la grosseur des caractères, l’application augmente les interlignes seulement, merci de corriger.

**Developer response:** Bonjour, ce type de problème est normalement causé par une mauvaise configuration du fichier ePub. Vous pouvez nous contacter à aide@demarque.com si vous souhaitez faire un suivi avec nous. L'équipe Cantook

### 2/5 — C’était parfait dommage

*2025-01-15*

C’était l’appli parfaite pour lire sur tablette j’ai tout aimé… jusqu’au moment de réaliser que l’équivalent de 2go de ePub équivalait presque à 40go d’espace mémoire sur la tablette. Beaucoup trop energivore je n’ai trouvé aucune solution à part supprimer l’app

### 2/5 — Cannot choose format in OPDS

*2025-01-05*

Not able to choose what format to download for books on OPDS server when a book has more than one.

### 3/5 — Nice but basic

*2024-11-30, version 1.11.3*

You can’t adjust the margins so the text fills the screen. The issue is immediately obvious when reading one of the free books, Alice in Wonderland.

### 2/5 — False advertising regarding Calibre support

*2024-09-23*

If you don’t have authentication you don’t support Calibre. Sending some message that it needs authentication is not very helpful if you don’t have a mechanism to support it….

### 3/5 — No sync?

*2024-09-22, version 1.11.3*

Sounded great. Apps for iPad, iPhone, and Mac. Supports OPDS. Unfortunately, each app is a silo when using OPDS. Even if you’re connecting to the same library, accounts don’t sync, books don’t sync, read status doesn’t sync.

### 1/5 — Application compliquée

*2025-09-21*

J’ai acheté un livre en ligne dans un cadre scolaire et il fallait absolument utiliser cette application. Sur mon téléphone ça fonctionne mais mal, ce n’est pas fluide, pas d’option de dicter le livre. Sur mon Mac j’ai tout essayé mais rien ne fonctionne.

### 1/5 — Mauvais

*2025-09-16*

VOUS NE POURREZ LIRE LES LIVRES ACHETÉS

### 1/5 — Terms and Privacy

*2025-07-17*

The Terms of Use and the Privacy Policy leads to a blank page. The Developer’s Privacy Policy on this download page is also blank. The website requires the acceptance of cookies before I could read Terms of Use. For me that’s a no.

### 1/5 — How do I import my books?

*2025-06-07*

The startup asked to import my books. After selecting one PDF, the import window closed and my book was there. Great, but I can’t find any way to add more of my collection. No, I won’t be emailing support so respond to this review here.

### 1/5 — The app is spyware.  Not usable in current form.

*2025-03-29*

The app has potential, but it’s not usable due to several fatal flaws:

-Categories function totally broken. Can’t create categories, so no way to organize books.

-Changing font size or color is incredibly clunky due to full screen settings page that obscures the effect of font size changes: you just blindly push + or - buttons umpteen times

-Predatory and unacceptable privacy policy. It tracks what you read, including content, notes, and highlights, and sends it back to the developer.  This is a total non-starter and is absolutely unacceptable.  Even in countries where the privacy of books you check out from the library is protected by law, this app wants to spy on you.

The developer should respect the absolute privacy of what you read and the notes you take, or get out of the business.  This behavior is disgusting.

### 1/5 — Terrible App

*2025-01-29*

Cannot find login info or migrate books from my PC. Why can’t they just use Kindle so that it is easier to use and I can read my books.

### 1/5 — Beware

*2024-11-07*

I haven’t downloaded this app but it shows in my apps list as requiring an update. Fishy.

**Developer response:** Hi, the app was previously called "Aldiko Next" and has been rebranded. If you had downloaded Aldiko on your phone, that is why you might not recognize the app.
Best,
The Cantook Team

### 1/5 — Livres et app aldiko disparus

*2024-06-14*

Je n’ai jamais été informée du passage de aldiko à une autre app. L’application et mes livres téléchargés et achetés ont tous disparus, comment les retrouver? Au secours, merci

### 1/5 — Can we have the old app back please?

*2024-05-02*

With the beautiful red icon and clean design

Thanks!

**Developer response:** Hello, we are sorry you did not have a positive experience with our app. Could you please explain in more details the problems you had with the app? We will forward it to our tech team for future developments. please contact us at help@demarque.com. The Aldiko team

### 1/5 — Lecteur déficient

*2024-04-25*

La lecture assistée est déficiente. Votre lecteur lis les en-têtes de pages  à haute voix, ce sont des informations inutiles et ça rend l'expérience insupportable.
Votre application est nulle et n'est qu'une pâle copie de lecteurs bien conçue comme Thorium ou Livres de Apple.

**Developer response:** Bonjour, vous pouvez nous contacter à aide@demarque.com pour que l'équipe de développement jette un coup d'oeil à votre problème. L'équipe Aldiko

### 5/5 — is the app still being updated???

*2026-05-10*

i hope it is. it’s my favorite book reader.

i wish it had the “save style,” like how it looks, that yomu did. because it’s hard to correctly transfer a styling change that one makes from one book to another.

another thing i wish it had is a few more fonts, but if not, that’s all right.

one thing that i’d love is changing how scrolling is tracked in scroll mode while TTS is on, or being able to press and hold a word and the bar pops up and having an option for TTS to start there instead of the first paragraph the page is at when turning on tts mode.

### 5/5 — This is great!

*2025-11-01, version 1.12.3*

Amazing reading app, only suggested features would be custom order in collections and selecting specific books for widgets. Best pdf reading app I’ve used so far tho :D

### 5/5 — Smooth app just like Aldiko

*2025-09-20*

I like the cloud feature and would like to suggest a feature or tab where you could see all your highlighted texts in one place.

### 5/5 — Fixed opds

*2025-07-29*

I‘m not sure what causes the crashes but I guess it was not clientbased in the end so I fixed the rating.

### 5/5 — Works well with Internet Archive LCP files

*2025-06-07*

Zero complaints. Does what it's suppose to.  Just download a LCP file from the Internet Archive (which is a small data file and not the book itself), from the Files application "share" that downloaded file to Cantook, and after adding the requested passphase (your email address used to login to IA) Cantook dutifully downloads the PDF or EPUB and opens it up. I couldn't ask for more. Being able to so easily read IA LCP PDFs on the iPad is much better than using my MacBook. Credit to the Cantook's UX designer for a clean interface. Highly recommended and thanks Aldiko for making this application.

### 5/5 — Ｂｅｓｔ  so far

*2025-06-02*

This is really impressive and I so much love how it works. Thank you so much for creating this 🙏♥️

I now read much more better than I used to on phone

### 5/5 — Feature Request

*2025-03-20*

It is a great reading application and I use it on daily basis. I had one feature request, that Highlight of the selected text in the book should be first option while reading the book. 
This would really make it easy to highlight text and add value to the readers.

### 5/5 — Très bonne appli

*2025-01-30*

Très bonne appli au style simple et épuré - navigation facile et claire.

### 5/5 — Schlicht, einfach, schön

*2024-09-26*

Feature request: Kavita works like a charm > maybe support for kavita api, so that we can use kavita features like such as volume filtering etc.

### 5/5 — Nice and simple e-reader

*2024-09-06*

This is definitely one of the better e-readers I've found on the here. A lot of the ones I've used either have a horrendous UI, or the book formatting looks awful, but this app gets both of those things right and for that it deserves 5 stars.
