Hear a word you don't know? Say "Hey Siri, define that in Unpack" or shake your head with AirPods on. Get the right definition for what you're listening to.
Pause a podcast to look up a word? Never again.
Unpack is a podcast player that listens with you. When you hear a term you don't know, ask Siri or shake your head with AirPods on and get a definition that's right for the conversation. "UGC" in a marketing podcast means User Generated Content, not Uganda. Unpack already knows.
HANDS-FREE, IN THE MOMENT
• Say "Hey Siri, define that in Unpack." Works with the screen off, phone in your pocket.
• Shake your head with AirPods Pro, Max, 3, or 4 to trigger a definition. Nod or shake to navigate. Hear the answer spoken back.
• Built for driving, cooking, running, and the gym, when picking up your phone isn't an option.
• Tap any word in the live transcript to define it instantly.
DEFINITIONS THAT FIT THE CONVERSATION
Generic dictionaries don't know what you're listening to. Unpack reads the transcript around the moment you ask, so the definition matches the topic: economics, biology, marketing, history, whatever the show is about. Same definition quality for free and Premium users. The AI is not a paywall.
MORE THAN SUMMARIES AND HIGHLIGHTS
Other AI podcast apps summarize an episode or save the good parts for later. Unpack works on the part you didn't understand, while the episode is still playing. Definitions are generated on your device first using Apple's on-device model, so most lookups never leave your phone, and they work without a signal.
LEARN, DON'T JUST LOOK UP
• Every term you define joins your personal glossary, sorted by subject.
• Unpack quizzes you on terms days later, so they actually stick.
• See how many terms you've learned and which subjects you're strongest in.
• Premium adds comprehension quizzes during playback, checking what you understood and not just what you heard.
• Premium highlights unfamiliar terms in the transcript before you even ask, based on what you've looked up before.
A REAL PODCAST PLAYER
• Subscribe via RSS or import your shows from Apple Podcasts, Overcast, Pocket Casts, or Castro with one OPML file.
• Speed control, skip, sleep timer, lock screen and Now Playing controls.
• Download episodes for offline listening.
• Live Activity and Dynamic Island while you play.
PRIVACY-FIRST
Your podcasts, your glossary, and your listening history stay on your device. We never see them. Definitions run on-device first. When one needs the cloud, it goes through our proxy with no identity attached, and Settings has a switch to turn that off entirely. Read the full policy in-app.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Podcast search now shows how many episodes a show has and when it last published, so shows with the same name are easy to tell apart.
Downloading a second episode from a show no longer overwrites the first. If one of your downloads has been playing the wrong episode's audio, delete it and download it again. Downloaded episodes also stay out of your iCloud backup now.
The AirPods head gesture no longer listens while your audio is playing on the phone speaker. Put your AirPods in and it picks up from there.
