Not getting the photo you want? The composition feels off, the angle doesn’t work, and it’s hard to explain what to adjust. With OneSnap!, you can preview your partner’s camera in real time. See the frame before the photo is taken, guide the pose and composition, and stop guessing. OneSnap! recreates the “remote preview + shutter” experience from Apple Watch, but extends it to two phones: You see the frame here. They shoot over there. Clear communication, better photos, together. --------------- Use Cases - Collaborative Shooting The person being photographed can view the live camera preview on their own device. Both of you see the same frame, adjust together, and get better results faster. - Assisted Selfies Set the phone in place and use the other device to preview and press the shutter. Take natural, well-framed selfies — even when you’re on your own. - Extended Perspectives One device previews, the other captures. Move the shooting phone to high angles, low angles, or tight spaces while still seeing the view. Discover new angles and more creative compositions. - Additional Scenarios · Photograph animals from a distance without disturbing them · Use remote shutter to reduce shake · Group photos without walking back and forth Flexible for everyday shooting situations. --------------- Core Features - Live Shared Camera Preview Shooting and preview are synchronized so both sides see the current frame. - Remote Shutter Control Either person can take the photo from their own device, making it easy to capture the right moment together. - Private Peer-to-Peer Connection OneSnap! uses direct device-to-device communication. No remote servers. No uploads. The camera feed never leaves your devices. --------------- Every photo is a shared decision. Every shot is a shared moment. OneSnap! — Capture together.
