What you get
Bring your own Google Sheet
Cards live in the user's Google Drive as a normal spreadsheet. Edit on a laptop, sync instantly to the phone. The app does not store a duplicate copy on a remote server.
Speak mode (recall with STT)
Tap to record, say the answer, and see it transcribed and graded on the spot. Pronunciation feedback comes from the same speech recognition stack the device uses for dictation.
Listen mode (hands-free review)
Auto-play TTS for each card with adjustable pause between cards, speed, voice per side (Q/A), and flip behavior. Works as a passive review while commuting or doing chores.
AI card generation
Describe a topic or upload up to 5 photos of study material; Gemini turns it into Q&A cards with a sensible sheet title. Useful for converting textbook pages or vocabulary tables into reviewable cards.
Premium TTS voices
Google Cloud TTS voices (vs the device's default voice). Audio is cached per text + voice combo, so repeated reviews are free after the first synthesis.
Stats and reminders
Daily/weekly/monthly attempt counts, cumulative cards learned, accuracy, per-sheet performance. Optional daily study reminders.
Short URLs for phone → desktop
Share a word-based short URL (e.g. vcrd.quest/swift-fox-7) that resolves to the underlying Google Sheet — type it on a laptop to edit cards without copy-pasting a 50-character spreadsheet URL.
Who uses it
Language learning
Vocabulary, phrases, and conversation drills with native-quality TTS in 14+ languages. Speak the target language; the app checks pronunciation against the expected answer.
School & professional exam prep
GRE, TOEIC, civil service, CDL interview, medical boards — anything that boils down to question-answer recall. Real users prep CDL Interview, school subjects, and entrance exams.
General memorization
Historical dates, scientific definitions, scripture verses, song lyrics, codebook quotes. Topic-agnostic: any Q&A pair you can write into a sheet.
How it works
- Put your cards in a Google Sheet. Two columns: question and answer. Edit on a laptop with the full Google Sheets keyboard.
- Add the sheet to VoiceCards. Sign in with Google. The app reads the sheet directly from your Drive.
- Study by voice. Speak mode for active recall (STT grades your spoken answer). Listen mode for autoplay TTS review.
- Track and adjust. Per-sheet stats show daily speak/listen counts, accuracy, and trends. Set a daily reminder if you want one.
Languages
Card content can be written in any language. TTS and STT are tested with Korean, English, Japanese, Chinese (Simplified), Spanish, French, German, Italian, Portuguese, Russian, Vietnamese, Thai, Indonesian, Arabic. The app interface is localized to English, Korean, Japanese, Simplified Chinese, Spanish, French, and German.

Privacy
Cards stay in the user's own Google Drive — VoiceCards does not store a duplicate copy on its servers. Learning statistics (attempts, accuracy, streaks) are kept on Supabase, scoped to the signed-in user. The app requests microphone access only when the user taps record in Speak mode.
