TransferViewer

A real-time photo viewer app for studio and on-location shoots. Displays photos transferred via Wi-Fi FTP from your camera instantly on your tablet.
Available in 7 languages: Japanese, English, Korean, Spanish, Simplified Chinese, Traditional Chinese, and French.
■ Instant display on transfer
Photos transferred via Wi-Fi FTP from Sony, Canon, Nikon, or Fujifilm cameras are displayed automatically the moment they arrive. Keep your shooting rhythm without interruption.
■ Receives in background and during sleep
FTP transfers are received even when the app is in the background or the device is asleep. Leave your tablet aside and focus on shooting.
※ Reception may be interrupted depending on your device's power-saving settings, such as Wi-Fi hotspot auto-sleep. For extended shoots, we recommend disabling power-saving features.
■ Zoom optimized for focus checking
Pinch to zoom or double-tap to enlarge in steps. Each double-tap increases the zoom level, letting you check focus and fine details clearly. Performs well even with high-resolution JPEGs, and supports cameras with 50MP and 100MP+ sensors.
■ Real-time EXIF display
ISO, aperture, shutter speed, and focal length are displayed on screen at all times. Check your exposure without leaving the app.
■ Select function
Mark your favorite shots with a check, then export the file name list as a text file. The exported list works with "CheckRAW Select" — a free Windows app by TRES Inc. — to instantly extract the corresponding RAW files from your shoot.
■ Export function
Export checked photos as JPEGs to your device's gallery. Export one at a time or multiple shots at once.
■ Delete unwanted shots
Use the trash button to delete unnecessary shots on the spot.
■ Folder management
Organize shoots by job or date using separate folders.
■ Compatible cameras
Sony / Canon / Nikon / Fujifilm (models with Wi-Fi FTP transfer support)
※ FTP transfer timing varies by camera manufacturer and model. Some cameras, such as the Fujifilm GFX series, begin FTP transfer only after writing to the memory card is complete. This may result in a delay of several seconds to tens of seconds between shooting and display. This is a camera-side specification.
■ Free and Pro versions
The free version supports up to 2 folders with 36 photos each. Upgrade to Pro via in-app purchase for unlimited folders and photos.
Requires Android 12 or later
Recommended RAM: 6GB or more (operation confirmed on 4GB devices up to approx. 24MP)
※ For cameras with 50MP or more, RAM of 8GB or more is recommended.
