One take. Both cameras. DuoTake records with your front and back cameras at the same time, so you capture your reaction and the moment in front of you together. No filming twice, no stitching clips later. Built for creators who post everywhere. Reactions, reviews, unboxings, food tours, travel vlogs and family moments all look like a two camera shoot from a single iPhone. FOUR LAYOUTS ONE TAP AWAY Picture in Picture The rear camera fills the frame while your face sits in a small window. Drag it anywhere, pinch to resize and choose a rounded, capsule or circle shape. Perfect for reactions, reviews and walkthroughs. Split Screen Front and back views side by side or top and bottom in one finished video. Great for comparisons, interviews and duets. Dual Recording Front and back views saved as two separate videos, giving you full freedom when you edit. Landscape and Vertical One take creates a 16 by 9 widescreen video and a 9 by 16 vertical video with matching sound and timing. Shoot once and post to every platform without reframing or reshooting. LOOK AND SOUND YOUR BEST Live beauty and filters you can preview before you hit record. A scrolling teleprompter keeps your lines on screen so you never lose your place. Countdown timer, grid, exposure control and stabilization in one quick panel. Tap to switch zoom levels and flip the main camera in one move. YOUR PORTFOLIO IN ONE PLACE Every recording lands in your in app portfolio. Preview, share or save to Photos anytime. The smart editor reframes your footage into different aspect ratios so one clip works on every platform. FREE AND PRO Dual camera recording, all four layouts and the portfolio are free to use. The free version records up to 720p at 30 fps with clips up to 2 minutes, and exports include a watermark. DuoTake Pro is a one time purchase, not a subscription.

Nothing is uploaded to any server and there are no ads. Simultaneous front and back recording requires an iPhone that supports multi camera capture.

About

Interval Pro

Read full description

The iPhone's timelapse mode controls nothing. DSLR workflows control everything, but weigh a ton. Interval puts full control in a simple app. LOCKABLE MANUAL CONTROLS ISO, shutter speed, white balance and focus: leave each setting on auto, dial it in by hand, or lock it on the current reading. That lock is what removes flicker, the flaw that gives away amateur timelapses. THE INTERVAL CALCULATOR Give it the length of your event, the video length you want and the frame rate: Interval computes the interval and tells you the photo count, the storage and the battery you need before you even start. No more session ruined by poor planning. STABILIZED HYPERLAPSE Set a target point on your subject, walk, realign the ghost frame of the previous photo, shoot. At export, the analysis aligns every photo and smooths the path. Fluid results, no rig, no tripod. BUILT FOR LONG SESSIONS The screen genuinely lowers its brightness while capturing to save battery. The app pauses by itself if the iPhone gets too hot, then resumes. An incoming call no longer ruins anything: the session picks up exactly where it stopped, locked settings included. PRECISE FRAMING Native 4:3, 16:9, 3:2 or square, with a guide showing exactly what the video will contain. Rule of thirds mapped to your chosen frame, and a horizon line to set the phone up straight. YOUR PHOTOS STAY YOURS Every session keeps its full-quality HEIC photos. Re-export in 1080p or 4K, at 24, 25, 30 or 60 frames per second, as many times as you like. Nothing is thrown away. NO DATA COLLECTED No account, no server, no trackers. Your photos and videos never leave your iPhone. That is not a marketing promise: the app has nowhere to send anything. ONE PRICE, EVERYTHING, FOREVER The app is free with all manual controls, 1080p export and three full-quality exports to try everything. A one-time purchase unlocks 4K, removes the watermark and lifts the export limit. For good. Never a subscription. Built by a photographer who actually uses it in the field.
