A little more help.
A bigger world to explore.

Unfold the story. Make room to think.

Open iPhone Duo into a landscape storybook: a clue or story in one pane, your ideas or an investigation notebook in the other. Optional help, worked examples, read aloud and the dictionary give you familiar ways to explore. Your answer and hint stay with you as you fold and turn.

Listen at your own pace.

Read stories, clues, visible answer choices, open help steps and dictionary entries aloud with your device’s built-in English voices. Answer choices include their A, B, C and D labels in the spoken order. Pause, resume or stop; choose a voice and a comfortable speed. The sentence is highlighted as it is read, with word highlighting when the voice supplies timing. The page follows the spoken text as it reaches the bottom of the reading area. Listening leaves answers and progress unchanged.

Keep a dictionary close.

Look up a word from the top bar, or double-click reading text with a mouse for a quick definition. Open the full entry when you want more meanings, and listen to the headword or its definition. Open English WordNet is bundled in the native app and saved in the browser after a small first download when browser storage is available. Lookups stay on your device.

Find your way from the first visit.

A four-step introduction explains subjects, stories, clues, listening, word lookup and family settings. Skip at any time, or reopen it through Family → Show me around.
