Press anything
Keyboard, gamepad, MIDI pad, Arduino, a big red HID button. Open the Inputs panel, hit Bind next press, press the thing. Done.
Press anything.
Count down. Snap.
OhSnap! runs full-screen with your branding, not ours. Map any button on any USB device by pressing it once, swap the background from a camera, a still or a video on the spot, and every photo lands in a folder you can find.
- One installer, no product keys
- Works offline at the venue
- Admin on Ctrl+Shift+A, never on screen
Backgrounds, live
Live camera, still image, looping video or a flat colour. Drop a file into the panel and the stage swaps it without leaving idle.
Your brand, every pixel
Logo, frame, watermark, text, and any number of logos and stickers you drag, resize and turn right on the screen, with a live picture of what will print. Positioned in percentages, so what you see on the wall is what lands in the photo. Strips get a footer for the client's logo. Export the preset, load it on the next machine.
The stage is theirs. The drawer is yours.
Guests see only what the client set up: their logo, their prompt, their frame. Everything else sits in a drawer on Ctrl+Shift+A, with an icon per panel, a dark theme for dim rooms, help built in, and a PIN when the laptop is left alone at the venue. The pictures are the real app.
Every panel, explained
How a snap happens
- 1Idle. Full-screen, cursor hidden, whatever background you chose.
- 2Trigger. Any mapped input. A tap on the screen if you allow it.
- 3Countdown. 3, 5 or 10 seconds, a flash, and a tick if you want one.
- 4Composite. Background, guest, frame, watermark, text, at full camera resolution.
- 5Review. Keep, retake or print, and a QR to save it to a phone if you switch that on. Then back to idle for the next guest.
