### 1/5 — Can't highlight

*2026-01-11, version 2.6*

Highlight function does not work.

### 3/5 — Can not highlight on iOS

*2025-11-25, version 2.6*

I have tried everything and I can not highlight the words in the textbook.

### 4/5 — Dark/ Night Mode?

*2025-10-13, version 2.6*

How do I use DARK/ NIGHT MODE for reading my books?

The white background feels too bright at times.

Thank you

### 1/5 — Mal

*2025-10-06, version 2.6*

Horrible aplicación , no me deja entrar

### 1/5 — Sloooooooooow

*2025-09-12, version 2.6*

It’s so slow it’s impossible to read in!

### 1/5 — No puedo iniciar sesión

*2025-09-04, version 2.6*

No puedo iniciar sesión.
Registró mi correo institucional y no es válido según la aplicación

### 1/5 — No dark mode is a dealbreaker

*2025-06-21, version 2.6*

Give us options to select or change the voices for the audio. 

For a reader app, dark mode is quite essential. The lack of dark mode makes this app unusable especially at night.

The last update for this app was 4 years ago.

### 1/5 — Highlight text option

*2025-05-06, version 2.6*

It’s an amazing app, but just because the option to highlight doesn’t work I give it a 1*. It looks like there’s no plan to fix it any time soon.. I mean last update was 2 years go which is really frustrating.

### 1/5 — Still can’t highlight and write notes on iPad in 2025

*2025-02-08, version 2.6*

Such waste that I can't even highlight or write notes through my iPad. I'm so looking forward to studying on the go but seems like this ain’t gonna work

### 1/5 — Please fix the highlight and notes functions

*2024-09-14, version 2.6*

They are like half the point of the app! Otherwise it’s just a basic e-reader.

A cleaner Library
•  Expired books no longer show up by default, so you don’t have to scroll past them to find the book you’re looking for.
•  Your expired books can still be viewed by applying the new Expired filter.

Book returns
•  If your school lets you “borrow” books, you can now return ones you don’t need anymore before their expiration date.
•  Returning books early removes clutter from your Library and makes books available to others who need them sooner.
