BiLens — Two Cameras, One Perfect Shot You don't need the latest iPhone to shoot with both cameras at once. BiLens uses your front and rear cameras simultaneously, capturing two perspectives in a single shot to make your photos and videos more lively and fun. Travel vlogs, parent-and-child moments, food and street exploring, everyday memories — capture it all in one shot. 【Dual Cameras, Shot Together】 Turn on the front and rear cameras at the same time and capture both views with one tap. The front camera records your reaction while the rear captures the scene in front of you — truly "what you see is what you shoot." 【Live Photos】 Your dual-camera shots can be Live Photos too. Just touch and hold to replay the motion and sound of the moment, with support for 48MP high-resolution Live Photos. 【Flexible Layouts】 - Picture-in-Picture: a rectangular or circular window you can freely drag and resize; two-finger tap to switch shapes instantly - Top/Bottom or Left/Right split screen: both views shown equally - Diagonal split: left- or right-leaning creative framing for a distinctive look - Swap the main and secondary cameras with one tap for full control over your angles 【Pro-Level Capture】 - Up to 48MP high-resolution photos and 1080p / 4K ultra-clear video - Selectable 24/30/60fps frame rates with video stabilization - Zoom from 0.5x ultra-wide to 5x telephoto - Multiple ratios: Full, 16:9, 4:3, 5:4, 1:1, 9:16 - Portrait-and-landscape cinematic mode with 4:3 recording 【Beauty & Color】 - Skin smoothing and brightening beauty effects, rendered in real time with high-performance Metal — for both photos and video - Fine-tune with the color panel: brightness, contrast, saturation, grain, coarse grain and more - A range of filters and film-grain textures to give your shots more character 【Photo Editor】 Fine-tune every shot right after you capture it: - Text tool: horizontal or vertical layouts, multiple fonts, one-tap outlines and background colors - Smart eyedropper: pick any color straight from your photo for perfectly matched styling (Live Photos too) - Aspect-ratio fill: switch ratios and your image fills the crop frame automatically - Export in original quality, with date and location preserved 【Teleprompter】 No script memorizing for vlogs or pieces to camera: on-screen floating prompts with adjustable speed and font size let you speak smoothly right into the lens. 【Tap to Focus & Exposure Control】 Tap anywhere on screen for precise focus, swipe up or down to adjust exposure, and press and hold to lock focus and exposure (AE/AF Lock). 【Date & Location Watermark】 - Multiple time formats: 24-hour, 12-hour, US/Europe/Asia styles, ISO 8601 and more - Multiple location formats: city name, GPS coordinates, full address, altitude and more - Pin the watermark to any corner or drag it freely; adjustable opacity, lockable to prevent accidental moves, with custom text support 【Shooting Countdown】 3-, 5-, or 10-second timer, perfect for selfies and group photos. 【Audio Settings】 Choose mono or stereo, with AAC or Apple Lossless audio quality. 【Flexible Photo Saving】 - Merged: a single photo containing both camera views - Separate: the merged photo plus the original front and rear shots — 3 photos in total - Orientation and metadata handled just like the native camera 【More Details】 - Grid lines to help you compose, with customizable PiP border color and thickness - An easy onboarding guide, a clean and elegant interface, and smooth performance Have suggestions or feedback?
