# BeReal-Style Dual-Camera UI (Learn the Pattern, Free) > By Lawrence Arya, Founder & CEO of VP0. Published 2026-05-30, updated 2026-06-02. 4 min read. > Source: https://vp0.com/blogs/bereal-style-dual-camera-ui-template The interaction is the interesting part; the camera plumbing is a native capability. **TL;DR.** BeReal's pattern is simultaneous front-and-back capture plus a time-window prompt. Learn it and build the UI (dual preview, single shutter, composite, prompt) from a free VP0 design with your own brand. Use the platform's multi-camera capture (AVFoundation) for the photo, with a fallback for unsupported devices, and only upload with consent. BeReal popularized a distinctive capture pattern: when prompted, you take a photo with the front and back cameras at once, combined into a single dual image. It is a fun, recognizable interaction worth learning if you are building anything camera or social, with the usual rule: learn the pattern, not the brand. The short answer is, learn how the dual-camera capture and the time-window prompt work, build the UI from a free VP0 design with your own identity, and use the platform's multi-camera capture API for the actual photo. The interaction is the interesting part; the camera plumbing is a native capability. ## What to learn from the dual-camera pattern Two ideas make BeReal's capture memorable: simultaneous front-and-back capture (a composite of what you see and your reaction), and a prompt-based, time-boxed moment that creates a shared ritual. For the UI, that means a capture screen showing both camera previews, a single shutter, a clean composite result, and a prompt/notification that opens straight into capture. Engagement of this kind drives the daily habit retention depends on (around [25%](https://getstream.io/blog/app-retention-guide/) day one). The technical piece, capturing both cameras together, is handled by the platform (AVFoundation multi-camera on iOS), so your work is the interaction and composition UI. ## How to build a dual-camera capture UI VP0 is a free iOS design library for AI builders. Pick a camera or capture design, copy the link, and have Cursor or Claude Code build it in [React Native](https://reactnative.dev/) (with a camera library supporting multi-cam) or SwiftUI using [AVFoundation's multi-camera capture](https://developer.apple.com/documentation/avfoundation/avcapturemulticamsession). Show both previews (a small inset over the main view, like the familiar layout), a single shutter, and a composite preview with retake and share. Handle the time-window prompt as a notification that deep-links into capture. Respect camera permission clearly, and never upload or log images without consent. Brand it as yours, not BeReal. For a related capture pattern, see [document scanner crop UI like CamScanner](/blogs/document-scanner-crop-ui-like-camscanner/). ## Dual-camera UI building blocks Here is what each part should do. | Part | What to get right | |---|---| | Dual preview | Both cameras, inset layout | | Shutter | One tap captures both | | Composite | Clean combined result | | Prompt | Notification opens capture | | Permissions | Clear camera consent | ## A worked example Say you build a daily-moment app. From a VP0 design, build a capture screen with the back camera full-screen and the front camera as an inset, a single shutter that fires both via the multi-camera session, and a composite preview with retake and post. A daily push prompt deep-links into capture for the time-boxed moment. Ask for camera permission with a clear reason, and only upload after the user posts. Brand it your way. One detail worth getting right: capture both frames at the same moment, not back-to-back, so the front-and-back pairing feels authentic rather than staged, that simultaneity is the whole point of the format. For the health-tracking side of a daily app, see [Oura ring companion app UI clone](/blogs/oura-ring-companion-app-ui-clone/); for a playful layer, [Telegram clicker game UI clone](/blogs/telegram-clicker-game-ui-clone/). ## Common mistakes The most common mistake is copying BeReal's name, logo, or exact look instead of learning the interaction. The second is building dual-camera capture from scratch instead of the platform's multi-camera API (and note older devices may not support simultaneous capture, so handle a fallback). The third is a confusing capture screen where the shutter or previews are unclear. The fourth is uploading or logging photos without clear consent. The fifth is no graceful handling when permission is denied or multi-cam is unsupported. ## Key takeaways - Learn the dual-camera and time-window pattern, not the BeReal brand. - Use the platform's multi-camera capture (AVFoundation) for simultaneous front-and-back; do not build it from scratch. - Handle camera permission clearly and only upload with consent. - Build the capture UI from a free VP0 design with your own identity (engagement drives retention, around 25%). ## Frequently asked questions How do I build a BeReal-style dual-camera UI? Learn the pattern (simultaneous front-and-back capture, a single shutter, a composite result, a time-window prompt) and build the UI from a free VP0 design with your own brand. Use the platform's multi-camera capture API (AVFoundation) for the actual photo. Is it legal to clone BeReal? Learn the interaction pattern, but do not copy BeReal's name, logo, or identity. Build your own brand on top of the learned capture flow. Can every iPhone capture both cameras at once? Multi-camera capture is supported on many but not all devices. Use AVFoundation's multi-camera session where available and provide a fallback (sequential capture or single camera) where it is not. How do I handle photo privacy? Request camera permission with a clear reason, only upload images after the user explicitly posts, and never log raw photos. Treat captured media as sensitive. ## Frequently asked questions ### How do I build a BeReal-style dual-camera UI?
