Frequently asked

You hear an expressive spoken line with one new word or pattern in it, guess what it means, then tap to reveal. Rate yourself Good if you got it or Again if you didn't. Flua adapts the next review to your memory; that two-button loop is the whole app.

No. Flua works fully without signing in — your progress lives on your device. An account is optional, and only used to back up and sync your progress across devices and to restore a purchase.

Yes. After your language and its audio finish downloading the first time, you can study with no connection at all. Syncing (if you use an account) catches up next time you're online.

Seven languages: French, Spanish, Japanese, Chinese, German, Italian and Korean. Each language is one path, checked word by word — nothing to choose between or configure.

Open Settings → Recalibrate my level any time to run a quick calibration — it estimates how many words you already know and drops you in at the right place instead of card one.

Go to Settings → Daily goal and pick a daily time (or a new-words target). Flua clears your due reviews first, then fits in as many new words as that allows.

Open Settings, sign in with the same email, and tap Restore purchases. Your unlock and your synced progress will come back on the new device.

It's your choice: own one language forever for $89.99, use one language for $39.99/year, or unlock every language for $14.99/month. Annual and monthly plans renew automatically until cancelled. Every plan includes every card we've published for your language, teaching 551 to 959 words so far, and future levels we publish are included. The first 150 cards are free with no account.

Plans bought in the app cancel in your App Store or Google Play subscription settings; plans bought on the web can be cancelled from your receipt email or by writing to us. Cancelling stops future charges and you keep access until the period ends. For a refund, email support@tryflua.com — purchases made through Apple or Google are refunded through their own store process, and we'll point you to the right place either way.

Completely normal, and most common early on. Flua uses expressive full-speed audio because that's the listening target you're training for. Lean on the sound, guess before you read, and it clicks fast. You can also slow playback in Settings → Audio speed.

Email support@tryflua.com with what happened (and your device model if it's a bug). We read everything and reply.
