CapWords

Point the camera at anything and CapWords identifies it, cuts the subject out of the frame, and turns it into a bilingual flashcard. It also reads text from signs, books and screens, so both objects and printed words become study material. Live Photos and video frames work too, which lets you capture things that won't hold still.

Each captured word lands as a designed sticker that keeps the image attached to the term. The visual link is the whole point: the photo becomes the memory anchor, so you recall where and when you learned the word. You can long-press a sticker to save it and reuse it in notes, chats or printed labels.

The review system tracks what you've captured and brings words back just before you'd forget them. It leans on the forgetting curve, and the app flags the words you stumble on most so your time goes where it matters. A hat icon on the home screen opens the review any time.

The app doesn't stop at a dictionary entry. It reads the context of your photo to give a meaning that fits, plus an example sentence and usage notes. That helps with words whose sense shifts by situation, where a bare definition leaves you guessing.

A daily counter tracks the words you've collected and your consecutive study days, which turns vocabulary building into a habit you can see. Seeing the streak grow is part of why people keep coming back, especially when a plain wordlist feels like a chore.

Beyond recognition, CapWords adds practice modes such as listening and spelling and example-sentence shadowing. These bridge the gap between recognizing a word and being able to produce it, which is where a lot of vocabulary apps stop short.

CapWords doesn't store the photos you capture and runs without its own servers. A photo is sent once to a third-party model for recognition, then discarded, and review progress syncs between iPhone and iPad through Apple's CloudKit. You can use the app without an account.
