Frequently Asked Questions

How do I import an EPUB file?

In the Library, tap Upload EPUB in the “Import your book” card and pick your EPUB file from your device or the Files app. Files up to 150 MB are supported. The book is securely uploaded to our server so TeakReader can process it for reading, vocabulary, and analytics. Link an account if you want easier access across supported devices.

How do I look up a word or phrase?

While reading, tap any word once. A popup shows its meanings, examples, pronunciation, and a translation in your language. To translate a phrase or sentence, press and hold to select it, then tap Translate. The same menu has five highlight colours.

How do I listen to a book (read aloud)?

Open a book, tap the middle of the page to show the controls, then tap the headphones button. TeakReader reads the page aloud, highlights each sentence, and turns pages for you. Use the small player to pause, change the speed (0.75× to 1.5×), or pick a voice. It keeps playing when your screen is locked.

The read-aloud voice sounds robotic. How do I get a better one?

TeakReader uses the voices on your phone. Tap the voice button in the player and follow the steps shown. On iPhone, download a free Premium or Enhanced English voice in Settings › Accessibility › Read & Speak (or Spoken Content) › Voices. On Android, install a high-quality voice in the Google text-to-speech settings.

How do I change the font, spacing, or theme?

In the reader, tap the middle of the page and then Aa. You can choose Light, Sepia, Dark, or AMOLED, ten fonts (including Literata, Atkinson Hyperlegible, and OpenDyslexic), text size, line spacing, margins, alignment, paragraph style, page-turn animation, brightness, and warm light.

How do I search a book or jump to a chapter?

Tap the middle of the page to show the controls. The list button opens the contents with the current chapter marked. The magnifier searches the whole book; tap a result to jump to it. After any jump, a “Back to” button takes you back to where you were.

Where are my highlights and bookmarks? Are they synced?

Tap the bookmark list button at the bottom of the reader. It has Bookmarks and Highlights tabs, where you can jump, change a colour, add a note, delete, or share all highlights. Bookmarks, highlights, and your reading position are saved to your account, so they are there on your other devices.

What are the tinted words and the “new words in this chapter” card?

Words you marked as Learning are lightly tinted in every book so you notice them when they come back. When you move into a new chapter, a card can show the new words in it so you can study them first. Both can be turned off under Learning in the Aa menu.

How do the flashcards work?

Every word you look up can be saved as a flashcard. TeakReader uses the FSRS algorithm (Free Spaced Repetition Scheduler) to schedule reviews at optimal intervals. Flashcards work in guest mode and linked accounts; linking an account helps keep your review history available across supported devices.

Does the app work offline?

An internet connection is required to start a guest session, link an account, import books, process subtitles, and use definition or translation features. Once a book is loaded, you can read it offline. Premium users can also download offline dictionary data for supported reading workflows.

How do I delete my data?

You can permanently delete guest data or linked account data from within the app (Profile → Delete Account, or Delete Guest Data for guests). You can also use the Account Deletion page or email us at support@teakreader.com. Deletion requests are processed within 30 days.

My book is not displaying correctly. What should I do?

Some EPUB files use non-standard formatting. Try: ensure the file is a valid .epub file (not PDF or MOBI), check that the file is under 150 MB, and try re-downloading from the original source. If the issue persists, email us at support@teakreader.com with the book title and author so we can investigate.

Is my reading data backed up to the cloud?

TeakReader stores reading data, imported books, and flashcards on our servers for your guest or linked app identity. Link an account if you want the most reliable way to pick up your library and progress on another supported device.

Which languages are supported for translation?

Translations are powered by Microsoft Translator, which supports more than 100 languages. Choose your language when you first open the app, and change it any time in Profile. If you skip that step, the reader asks for a language the first time you translate. Definitions are in English.
