I'm a product designer who built an app where you learn words from real video clips, then an AI tutor makes you use them in conversation

Wait 5 sec.

Hey everyone 👋 I'm a product designer by day (fintech, mobile apps). For the past year or so I've been building Voca in the evenings. It's an iOS app for learning English from real videos instead of textbook dialogues. Why I built it: English isn't my first language. Watching shows helped me understand more, but there were two problems. Words I looked up got forgotten within a week, and even the ones I remembered I never actually used when speaking. Passive vocabulary just stayed passive. So Voca does practice in two directions: 1. Input: watch and collect Pick clips you like: comedy, science, business, stand-up, animation (1000+ so far) Tap any word in the subtitles to see its meaning and translation in context Save it in one tap. Each word keeps the exact line it came from Review with spaced repetition, timed right before you'd forget 2. Output: speak and use Speaking practice with an AI tutor that knows your saved words During the conversation it nudges you to use them ("try using reluctant here"), so words move from "I recognize it" to "I can actually say it" Plus listening practice from real dialogue, a few mini-games, and a turtle button to slow down fast speech. Pricing, to be upfront: it's free with daily limits (5 min of watching and 5 new words per day, unlimited reviews). PRO removes the limits, and the yearly plan has a 7-day trial. I'd love honest feedback: Does the "watch → save → speak" loop make sense from the first screen? Is the speaking part useful, or does it feel like a gimmick?
