Great picture, terrible sound? Import the video and Voice Isolation hands it back with the noise gone — same footage, clean voice, captions if you want them. Most clips come back in about a minute. No desktop session, no re-syncing an audio file to your timeline. It works the same way on plain audio: voice memos, interviews, dictation, or anything you can share in from another app. ▸ WHAT IT FIXES • Wind on outdoor and beach clips • Café and restaurant chatter • Traffic and street noise • Room echo and reverb • HVAC hum, fan noise, and other steady backgrounds ▸ HOW IT WORKS Pick a video or an audio file, then the part you want — slide the handles and only that part is uploaded and cleaned. Voice Isolation runs it through an AI speech-enhancement model and blends the result back against your original. For video it puts the cleaned audio back onto your footage automatically, so what you get is a finished MP4 — not an audio file you have to line up yourself. One tap A/B: switch between the original and the cleaned version and hear exactly what changed before you export anything. Cleaning runs on our servers, so your clip is uploaded over an encrypted connection while it is processed. Uploads are deleted automatically within 48 hours, and we never train on your audio. ▸ CAPTIONS Write captions in one tap. They are transcribed on your iPhone, not uploaded. Fix any word, pick a style — Classic, Bold or Pop — and burn them into your video, placed clear of TikTok's and Reels' buttons. Pro exports SRT subtitles and plain transcripts too. Captions need iOS 26. ▸ BRING IT IN • Record in the app with a live level meter — or start recording straight from Control Center, the Lock Screen or the Action button • Import audio (M4A, WAV, MP3, AIFF) or video (MP4, MOV) from Files • Pull videos straight from your Photo Library • Send anything in from another app through the iOS share sheet • Run Clean Audio in Shortcuts, or ask Siri ▸ GET IT BACK OUT • Share the cleaned audio to any app • Save the cleaned video as a new MP4 — free with a small watermark, clean with Pro • SRT subtitles and transcripts (Pro) • Export as WAV (Pro) • Save to Files or Photos ▸ FREE • 3 cleans a day, up to 60 seconds each — on longer recordings, pick the part to clean • Audio and video draw on the same 3 — video is not walled off • Captions, with the full editor • Video export with a small watermark • Full A/B preview, player, and cleaned-audio sharing • Ad-supported ▸ PRO • No daily limit — clips up to 10 minutes, and 90 minutes of cleaning a month • Videos and captions without the watermark • SRT subtitles and transcripts • Podcast and Social loudness presets: the level podcast apps, TikTok and YouTube expect, with peaks held under the limit • WAV export • Adjustable cleaning strength, so you can dial back how aggressive it gets • Re-clean up to 10 saved clips in one batch • Zero ads ▸ SUBSCRIPTION Voice Isolation Pro Monthly — $7.99 per month Annual — $39.99 per year, including a 7-day free trial Payment is charged to your Apple ID at confirmation of purchase.

Teleprompter Duo

Features
Read full description

Teleprompter Duo makes it easy to record narrated videos: narrate over a photo, a video, or a document — or record your front and rear cameras at the same time. A built-in teleprompter keeps your script in view the whole time, without it ever appearing in the final video. It's built for anyone who needs to sound natural on camera — creators, marketers, educators, and presenters who'd rather read a script than memorize one. TELEPROMPTER, BUILT RIGHT IN • Scrolling script overlay that never appears in your exported video • Adjustable font size, scroll speed, text color, and background opacity • Countdown timer before scrolling starts • Smart pace-following: scrolling speeds up or slows down to match how you talk • Manual controls: play, pause, rewind, fast-forward, reset SCRIPT LIBRARY • Write and save multiple scripts • Import scripts from plain-text (.txt) files • Edit anytime, with autosave built in • Share scripts with teammates or collaborators DUAL-CAMERA & FLEXIBLE BACKGROUNDS • Your presenter camera appears as a movable, resizable picture-in-picture window • Choose what's behind you: a photo, a video clip, a live rear-camera feed (on supported devices), or a PDF document • Great for product photography, screen-recorded footage, slide decks, and printed materials RECORD IN MULTIPLE TAKES • Record as many clips as you need in one session • Preview and delete individual clips before finishing • Teleprompter Duo automatically merges everything into one finished video BUILT FOR CONTENT CREATORS • Product reviews & demos • Tutorials & how-to videos • Online course lessons • Talking-head videos for YouTube, TikTok, Instagram & Reels • Sales pitches, webinars, and presentations YOUR LIBRARY, YOUR VIDEOS • Review, favorite, and share your finished recordings • Save directly to your photo library • Delete clips or full recordings anytime Teleprompter Duo Pro unlocks unlimited video downloads and early access to new features, with monthly, annual, or one-time lifetime options. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your account settings.
