3/5Look up option not working after update
Hi Cantook team, After the update the option look up is not available, this is a very important option when reading a book since it allows you to read the definition of a word without exiting the app.

5/5Works well with Internet Archive LCP files
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.

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

5/5is the app still being updated???
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. <333

5/5Nice and simple e-reader
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.

2/5
Copying text to search or highlight a word/phrase/expression is major pain & ⚠️most likely an epilepsy risk due to the high amount of flashing.Cannot sort by expiry date,filter changes nothing. Speed control for TTS is not fine grained or accessible,it doesn't go slow enough.Books take a long time to load.Pretty simple to add Internet Archive PDFs on loan, remembers last page read & last book read.No dark mode for PDFs only color inversion works in phone settings for PDFs

why is there another reader app😞

3/5
It's a great app except for one extremely annoying defect. While in vertical scroll mode, even the minutest lateral drag of the finger causes flipping if pages/chapters. Nine out of ten times that I'm scrolling VERTICALLY, it still flips the page in whatever direction my thumb last found itself. Highlighting text is also a horror because there I've to drag my finger horizontally. After I finish my current book I am switching to another app, because this defect makes reading almost impossible.

This was my favorite e-reader, too many changes to the UI and options. Where's the option to import books from your external? Why the pale interface or the changes to the library , where's the recent reads? Too many why's . The UI and other options missing weren't broken, why fix them. Fix what's broken compatibility issues but please leave the rest alone. it's not about a positive experience .We might as well just buy physical books . this is what happens when other people take over

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.",

          "body": "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.",
