No. There is no sign-up. All 21 units, the audio and the phrasebook are inside the app and work offline.

iPhone 13 or newer (A15 chip or later). Older iPhones don't have enough memory for the speech model, so the app shows a message instead of the download button. Lessons, audio and the phrasebook work on every iPhone running iOS 17 or later.

1. Open the Translate tab.
2. The first time, tap Download model: a one-time download of about 950 MB (use Wi-Fi), then wait for it to get ready.
3. Tap the mic and let the other person talk. In Live mode each sentence is translated as they pause; in After mode everything is translated when you tap stop.

Yes, after the one-time download. It runs OpenAI's Whisper large-v3 speech model on your iPhone, so nothing is uploaded. Preparing it the first time can take a few minutes. You can delete it in Me → Translator to free the space.

It works best with clear speech, one sentence at a time, with the phone close to the speaker. Fast, slangy everyday Tehrani, mumbling, background noise or several people talking at once can come out less accurate or garbled. For long or fast talk, Live mode translates each sentence separately. It is machine translation: for anything important, double-check with a person. If a phrase comes out badly, email the example — failures help most.

No. Lesson audio is synthetic text-to-speech made with Microsoft's Persian neural voices (via edge-tts), not recordings of native speakers. The clips were then run through an automatic listening check: Whisper transcribes the audio and we compare what it hears with the intended Persian, and flagged clips get another look. That catches clear mistakes, but a machine check can't catch every unnatural stress, vowel or intonation.

Not yet. The words, spellings and romanization follow a written style guide and were checked in several review passes plus automatic linting, but no published teacher or native-speaker panel has signed off on the lessons. Treat it as a fast start, and check with the Persian speakers in your life.

In the app (version 1.0.1 and later), tap Report pronunciation under any new word card, or open the word in the Phrases tab and tap it there (long-press works too). Your Mail app opens with the word's ID, Persian spelling and finglish filled in; add what sounds off and send. Zood itself sends nothing. On 1.0, just email us the word.

Zood 1.0 is free: no in-app purchases, no ads, no account. If that ever changes in a future version, it will be stated on this page and in the App Store listing before it ships.

Zood isn't available in the EU yet. It is on the App Store in most other countries.

Not yet. Zood is an iPhone app for now. Android and web may come later, but there's no date. There is no sign-up list; this page will say when anything changes.

Zood is designed for iPhone (iOS 17 or later).

None reaches the developer. Progress and history stay on your iPhone. The only exception is an email you choose to send yourself, such as a pronunciation report. Read the full Privacy Policy.
