## What is SubjectCards?

Type a sentence you wish you could say in Vietnamese. It comes back as a flashcard with native audio, and spaced repetition brings it back the day before you would have forgotten it.

SubjectCards is for adults learning a language for a reason: a trip, a partner's family, a job in a new city, a grandmother who never learned English. Nothing here is a game. There are no points, and nothing asks you to protect a streak. There is a card with a voice saying it properly, and a schedule that knows when you need to see it again.

YOUR OWN PHRASES, IN A LOCAL'S WORDS

Type what you want to say in English. Up to three ways a local would put it come back. Each carries a short hint about who to say it to. The form you use with a shopkeeper differs from the one you use with a friend. Already know the words? Type them in the language and they come back as your card with the marks in place. Ask for something more casual or more respectful and the card changes. Pick one and the press makes it a card: Vietnamese on the front with a play control, pronunciation and English on the back. Cards you make are stamped YOURS.

The free plan includes three phrases of your own. Premium lifts that cap.

HEAR EVERY CARD

Every card has a play control on the front and the back. Audio plays when a card flips, so you hear the tones before you read the letters. Every card in the library plays for free, so you can listen before you add it.

SPACED REPETITION THAT SHOWS ITS WORK

Grade the card (Not yet, or I know it) and the SM-2 schedule decides when it returns. Today shows where each word stands, from new to learning to known, with how many come back tomorrow. Review ahead whenever you like. Studying is never locked behind the schedule.

A LIBRARY YOU BUILD FROM

Start with a curated core of 200 cards in nine categories, from greetings and food to directions and numbers. Add packs on top. Or make a subject of your own, name it for the trip or the person, and fill it from the library and your own phrases.

MONTHS, PRESSED

Practice on enough days in a month and you claim that month's seal, ink on paper. Miss a day and nothing breaks.

FOUR LANGUAGES

Vietnamese, Korean, Mandarin and Spanish, each with its own library and its own review queue. The first language is free. Premium opens all four.

WORKS ON A PLANE

Your cards and their audio live on the phone, and so does the schedule. Reviews sync when you are back online. No account is needed. Sign in with Apple or Google only if you want your progress on a second device.

FREE AND PREMIUM

Free: one language, a starter deck of about 25 cards built from your level and your goal, three phrases of your own, and a listen to every card in the library.

Premium: the full library with every pack across all four languages, and phrases of your own beyond the three-card cap.

SubjectCards Premium is $6.99 per month or $39.99 per year. The annual plan starts with a 7-day free trial. Payment is charged to your Apple ID account when you confirm the purchase.

### 5/5 — Using it to learn Vietnamese as an expat

*2026-09-08*

If you like learning with flashcards, recommend it. I can make cards for things I actually want to say and practice. Vietnamese tones are tricky, so having audio to hear how everything should sound is a lifesaver.

## Version history (last 3 releases)

### 1.0.2 — 2026-09-10

Your phrase is now a conversation. Type it in English and up to three ways a local says it come back. Type words you already know in the language and they come back as your card with the marks in place.

Also includes misc onboarding and product improvements.

### 1.0.1 — 2026-09-04

Tap a word. On a custom card that holds a full sentence, the key words now carry a dotted underline. Tap one to hear it on its own and see what it means in that sentence.

Vietnamese phrases now come back three ways: northern, southern, and a respectful form for someone older than you.

Subjects and packs can be removed from their own page or from Today, which now lists them separately.

Fixes for stale decks after a sync and for drifting card counts.
