Learn a language by talking (or texting) with realistic characters in realistic scenarios. Textbook dialogs are boring and artificial. Have your own dialogs about the situations and topics you care about. If you make mistakes, or need to use English words, don't worry! Your conversation partner can understand and keep the conversation moving. If you don’t understand something, translations, transliterations, and in-context explanations are only a tap away. After a conversation, get an in-depth review of how you did, with suggested improvements and ideas of where to take future conversations. You can even "snap a photo" to help you remember the conversation in the future. Supports 20 languages: Arabic, Chinese, Dutch, French, German, Greek, Hebrew, Hindi, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Swedish, Thai, Turkish, Ukrainian, Vietnamese Terms of Use: https://uptalkapp.com/terms Privacy Policy: https://uptalkapp.com/privacy

Shadowing, made simple. Paste any text — a news story, a podcast transcript, a page from your textbook — and SentenceDeck turns it into a sentence-by-sentence speaking drill: hear it, say it, hear yourself back. No scripted lessons, no grades. Just the method interpreters and polyglots swear by, applied to the exact text you want to master. HOW A SESSION WORKS For every sentence, SentenceDeck: 1. Plays a clear reference voice 2. Records you automatically — recording stops when you stop speaking 3. Plays your voice back so you can hear the difference Switch on A/B compare to hear reference and recording back to back, lock a tricky sentence to loop it, and change playback speed (0.75× to 1.5×) without regenerating audio. WHAT'S NEW IN 1.5 • A redesigned home screen: pick up where you left off, and see today's sentences, your streak and your lifetime total at a glance • A richer premium voice with selectable voice styles • Free Sample articles so you can try the flow before adding your own text • Backup & Export: premium audio is included in your device backup when backups are enabled and sufficient backup space is available. Only a SentenceDeck ZIP can import compatible articles and audio on a new device; practice progress is not restored. Exported merged audio is for listening only and cannot be imported • Clearer pricing: each sentence is generated as you practice. The same sentence is charged once and cached for replay with the same premium voice and style settings; changing the premium voice or style may generate it again and use characters again TWO VOICES — ONE IS FREE System voice: built into iOS. Free, offline, unlimited. Premium voice: natural, expressive male and female voices with several speaking styles. Pay only for the sentences you practice; nothing expires. 9 VOICE LANGUAGES English, Chinese (Simplified and Traditional), Japanese, Korean, Spanish, French, Italian, German.
