## About MarcX Studio

MarcX Studio is an independent app studio that builds small, practical apps for iPhone, with a focus on language learning, education and everyday tasks. The studio's own description is simple: it builds practical apps for everyday tasks, such as keeping loyalty cards ready and practising spelling and number listening.

The apps share a few habits. Each one does one job clearly. Most of them work without an account. They keep your data on your device unless you choose to back it up or share it. And they are free to download, with optional upgrades for people who want more.

The studio website, https://www.marcx.app, is available in many languages, including English, Chinese, Japanese, Korean, Spanish, French, German and others. The apps themselves are built for learners and families around the world.

This introduction covers the studio's main apps: Snap Spell, NumListen, 成语拾光 (Idiom Shiguang) and RooCards.

## Snap Spell: spelling practice from real school word lists

Snap Spell is an iPhone spelling practice app for the word lists students actually bring home. You scan a printed list, import a photo or screenshot, paste text or type the words. You then check the list before saving it, and the school's spelling stays exactly as written.

Snap Spell reads every word aloud and checks each answer. Missed words come back in Tricky Words, and each word is tracked as To Study, Practicing or Mastered.

### Who Snap Spell is for

- **Families with weekly spelling words.** Practise the exact list from school without reading it aloud every night.
- **Students preparing for spelling tests and spelling bees.** Run through the whole list alone before test day.
- **ESL/EFL families.** Every English word is read aloud, so practice does not depend on a parent's accent.
- **Teachers and tutors.** Classroom and tutoring lists become practice each learner can repeat.
