Trigger Keeper
Read full descriptionHide full description
Prop your phone anywhere, step into the frame or keep your hands on the job, and say the word. Trigger Keeper hears it and takes the photo. No timer sprint, no asking strangers, no one missing from the picture. HOW IT WORKS Pick up to three trigger words. Any words you like, from "cheese" to something only your family says. Frame the shot and tap Play. Trigger Keeper starts listening. Say the word. The flashlight blinks so everyone knows it heard you, and the shutter fires. Or just smile. With Smile to shoot on, it takes the photo when everyone in frame is smiling. MADE FOR REAL PHOTOS Your word, not a wake phrase. No "Hey Siri" required. Works in English, Spanish, and Chinese. Burst mode takes three shots in a row, so blinks and mid-laugh frames don't cost you the photo. Live Photo support captures the moment around the moment. 0.5x ultra-wide to 6x zoom, with pinch or one-tap lens presets. 4:3, square, and 16:9 framing. The volume buttons and Camera Control work as a manual shutter. PRIVATE AND LOCAL Speech recognition and smile detection run entirely on your iPhone. Trigger Keeper contains no networking code at all. It cannot send your audio, your photos, or anything else anywhere. No account. No ads. No analytics. It works in airplane mode, because nothing it does ever needed the internet. Listening stops when you tap Stop, when you leave the app, or after 10 quiet minutes. A note on permissions: Trigger Keeper asks for full photo library access only because creating and managing its own album requires it. The gallery shows only the Trigger Keeper album. Your other photos are never read. GOOD FOR Family gatherings and holiday photos. Group shots where the photographer finally gets to be in them. Solo creators who need a camera operator. Anyone tired of the 10-second timer dash. Hands-busy moments: under a sink, up a ladder, or mid-repair, when you need a clear photo of a part to send to a colleague or customer. Requires iOS 17.2 or later. Ultra-wide and telephoto options appear on devices that have those lenses.

Natural RAW camera. Leica, FUJI & Kodak styles. Luxa is an iPhone camera for natural texture, expressive color, and thoughtful control. Choose how your photos are captured, explore film-inspired styles, and keep the experience simple—from framing the shot to saving the image. YOUR CHOICE OF IMAGE PROCESSING Choose from three imaging engines: • Process Zero RAW — develop Bayer RAW with Luxa’s own rendering pipeline for a more restrained starting point. • Apple ProRAW — combine RAW flexibility with Apple’s computational photography on supported devices. • Apple Processed — use Apple’s image processing for ready-to-share HEIF photos. RAW and ProRAW availability depends on your device and camera. The amount of Apple processing varies by engine. PHOTOGRAPHIC STYLES Explore looks inspired by Kodak, Fujifilm, and Leica—from warm film color and understated tones to expressive monochrome. Choose a lighter touch or a stronger look with adjustable style intensity. Monochrome styles use their full effect to preserve their character. Add grain with separate controls for amount, size, and roughness. Styles and grain are applied to the finished photo, so you can keep your attention on the scene. CONTROL, WHEN YOU NEED IT Adjust focus and white balance, or use manual shutter speed and aperture where supported by your device and iOS. Stay in Auto for everyday moments, then take more control when the scene calls for it. RAW MADE APPROACHABLE Save in RAW, HEIF, or RAW + HEIF, depending on the selected engine. Keep an original RAW file for editing, a finished HEIF for sharing, or both. When styles or watermarks require a rendered image, Luxa can save a HEIF companion alongside your RAW. THE FINISHING DETAILS Add a clean information-bar watermark with capture details and a signature. Use composition grids and a horizon level to help frame your shot. Open the built-in gallery to browse your photos, mark favorites, and view capture information. Less Processing. More Control. More Texture.
