The moment you press the shutter, your photo arrives wirelessly on your iPad / iPhone. ShotTetherPro is a wireless tethering receiver built for professional photographers — with every unnecessary feature stripped away. [Why we built it] ShotTetherPro was developed in-house by arcion Inc., a production studio specializing in photo and video shoots, focused only on the features that truly matter on set — rebuilt from the ground up to eliminate wasted screen space, slow transfers, and sluggish response. [Key features] ■ Stay on camera Wi-Fi Keeps your iPad / iPhone connected to the Wi-Fi of the camera you registered. Even if you open the app while connected to another Wi-Fi network (such as at home or the office), it switches to the camera’s Wi-Fi automatically. If the connection drops during a shoot, a banner at the top of the screen and a vibration let you know, and the app tries to reconnect every 10 seconds until it succeeds. You can also tap “Connect” to reconnect yourself. On iPadOS 18 / iOS 18 or later, once you register a camera, no confirmation screen appears on later reconnections. To set it up, join the camera’s Wi-Fi, register the camera’s name, and enter the Wi-Fi password once. ■ Register multiple cameras Register the Wi-Fi of several cameras, such as a second body, and simply choose the one you want to use from the list. ■ A perfectly optimized display An immersive UI that fills the screen with your photo, at maximum size with aspect ratio preserved. ■ Zero bloat — blazing fast and light No editing, social sharing, ads, or histograms. One tap from launch to the incoming shot; jumps instantly to the newest frame even in burst shooting (pausable while a client reviews). ■ Freely customizable thumbnail position & size Switch between horizontal scroll (bottom) and vertical scroll (left); drag to resize freely. ■ Works with every FTP-capable camera Any camera that can push photos over FTP / FTPS works, regardless of brand: Nikon Z9 / Z8, Sony α1 / α7R V, Canon EOS R5 / R3, FUJIFILM GFX / X-H series, Panasonic GH series, OM SYSTEM, and more. ■ Immersive single-photo viewer A full-screen viewer without unnecessary menus. Tap left/right for the previous/next shot. ■ Auto-display on arrival The newest photo appears the instant it's captured, even in burst shooting. Lock it for a closer look. ■ Photo grid & save to Camera Roll Browse in a grid, select multiple, and export to the iOS Photos app (Camera Roll) with one tap. ■ Project management One project per shoot, named automatically by date and time; switch with one tap. ■ 5-star rating Rate favorites instantly with the five stars on the right edge. Filter to speed up your selects. ■ Instant EXIF display ISO, aperture, shutter speed, focal length, and file name shown at the lower left — toggle on or off. ■ Aspect-ratio-preserving thumbnails Tell portrait and landscape shots apart at a glance and avoid mistaps.
