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 your trigger word. Any word 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. 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.

Atelier helps you fix a photo's composition after the shot. Everything runs entirely on your device — your photos never leave it, and no account is needed. Pro is a one-time purchase, not a subscription. AI-ASSISTED COMPOSITION Powered by Apple's on-device Vision, Atelier reads the subject, horizon, and negative space to suggest the best crop. "AI Auto-Compose" picks the ratio and straightens the horizon in one tap. Guides for rule of thirds, golden ratio, diagonal, and golden triangle let you fine-tune by hand. CROP & RECOMPOSE • Free crop and a full set of ratios (1:1, 4:5, 16:9, 9:16, 2.35:1, …) plus custom • Horizon straightening and subject-aware snapping • Batch auto-compose for many photos at once COLOR • One-tap film-style filters • Import your own .cube LUTs as custom filters • Manual exposure, contrast, highlights, shadows, saturation, temperature, and more • Press and hold the canvas to compare before/after BEAUTY • Natural skin retouch: smooth, brighten, relight • Slim face, enlarge eyes; lipstick, blush, eyeshadow • Faces are detected on device and only skin is affected — all offline FRAMES • Border (with corner radius), Polaroid, Fit, Info, and Palette frames • Any color via a color wheel; adjustable shadow and band height • Date stamp, caption text, or import your own logo • Multiple type styles: standard, serif, rounded, handwriting, and more EXPORT • Choose format (Original / HEIC / JPEG / PNG), size, and quality • HDR Ā· 10-bit export for supported photos • Multi-ratio batch export (e.g. 1:1, 4:5, 9:16 at once for social) • Optional removal of location (GPS) metadata PRICING Free to download, with a 7-day full trial on first launch. After that the core stays free (cropping, all filters, basic adjustments, basic beauty, single export, AI Auto-Compose & Auto-Color, all guides, HDR). Atelier Pro (a one-time purchase — pay once, unlocked forever) unlocks custom ratios & sizes, advanced color (saturation, effects), advanced beauty (reshape & makeup), advanced frames (Polaroid, Fit, Info, Palette, custom color, logo), .cube LUT import, GPS removal, and batch export — Pro effects are previewable, and the purchase removes the watermark and lets you export. PRIVACY Fully offline. Zero data collection, no ads, no tracking. Your photos stay on your device. For iPhone and iPad (iOS 18 and later). iPhone is portrait; on iPad in landscape the controls move to a side panel so the photo fills the height. IN-APP PURCHASE (Atelier Pro) A one-time, non-consumable purchase that unlocks the Pro features permanently. Payment is charged to your Apple ID at confirmation of purchase. It does not auto-renew and there are no recurring charges. The purchase is tied to your Apple ID and can be restored on your devices via "Restore Purchases".
