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?

Swipe through your photos, swipe up to mark what you no longer need, then review and confirm your deletions together. Organize photos, videos, Live Photos, and GIFs in your iPhone or iPad library. Keep your favorites, clear out unwanted items, and sort the rest into albums in Photos. Features: • Search image content and text on your device, such as “cat” or “order”, then open the results to continue sorting • Use Unreviewed Photos to track progress from swiping, marking for deletion, and sorting into albums • Use the app on iPhone and iPad, with layouts that adapt to iPad orientation and window size • Scroll the thumbnail strip to change the current photo; browse in order, in reverse, or shuffled • Review pending deletions, keep individual items, or clear all deletion marks at once • Turn on classification mode and drag photos or videos down onto album covers to add them • Create empty albums, reorder album covers, rename albums, and delete regular albums • Filter the overview by album, Favorites, Videos, or Screenshots, and jump to the newest item • Tap the expand icon or double-tap for a full-screen view, then pinch to zoom and drag to explore • Crop still photos freely or use 1:1, 4:3, 16:9, or 9:16, with undo during the current session • Toggle Live Photo autoplay from the Live icon, or hold to play the current Live Photo • Videos start muted; changing the sound control sets your preference for subsequent videos • Sync Favorites with Photos and share through the system share sheet • Adjust browsing and classification in a compact settings panel, with language and dark-mode controls Pro features (one-time purchase, no subscription): • Unlimited deleting: the free version deletes up to 30 photos a day; Pro has no limit • Video compression: adjust quality and size, including batches • Photo compression: shrink photos, including batches • Live Photo to still: keep the key photo or pick your favorite frame The three features share 3 free tries; only successful saves count. Everything is processed on your device, and originals move to To Delete only after the new copy is saved. After you grant Photos access, the app gradually prepares search on your device. The first scan takes time; you can keep sorting elsewhere in the app while recognition continues. Progress is saved for your next visit. Recognition may miss some matches. Image recognition and the search index stay on your device and are not uploaded. No account is required, there are no ads, and the developer runs no online service for the app. Your media and usage records are not uploaded automatically. When you choose to share, iOS passes the selected content to the app or recipient you choose. If an original is stored only in iCloud, the system Photos service may download it. Swiping up only marks an item. Nothing is deleted until you confirm in the iOS system prompt. Confirmed items normally move to Recently Deleted and remain recoverable during the system retention period. Support: asa24@qq.com Xiaohongshu: Asa阿洒
