Shadowing, made simple. Paste any text ā a news story, a podcast transcript, a page from your textbook ā 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 ā 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 (0.75Ć to 1.5Ć) 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.

Verdict
The clearest difference is in-app purchases: AyperZ at none against SentenceDeck's 3. AyperZ also leads on update cadence (every 2 months vs every 6 months) and iOS requirement (15.1 vs 17.0). SentenceDeck's advantage is ads (none vs shown). On price and device support there is nothing between them.
