A camera that shoots without you pressing the shutter. Sound, movement, brightness, heading, what's in frame — Snappy watches the sensors and releases the shutter the moment the condition you set is met. Use it with the phone on a tripod or a table, from a distance, when your hands are busy, or when you want to be in the picture yourself. The shutter button still works, of course. It's an ordinary camera too. ■ Eight trigger conditions • Shake — shoots when you shake the phone • Sound — shoots when it hears a loud noise • Motion — shoots when something moves in frame, with a threshold you can set by performing the movement once • Brightness — shoots when it gets brighter • Distance — shoots when something comes closer than the distance you set, using LiDAR or TrueDepth • Compass — shoots when the phone faces a heading you choose • Object — shoots when something you picked appears in frame, from 77 kinds including people, cats, dogs, birds, animals and cars • Gesture — shoots on a peace sign held up to the camera, or on both arms raised, which reads from right across a room Most conditions can be flipped to shoot when the value *falls* instead. When it goes quiet, when it gets dark, when the movement stops — the reverse works too. ■ Set the threshold with your finger The indicator just above the preview shows what the sensor is feeling right now. Drag the white line and the threshold moves with it, while you watch the frame. No need to open Settings. ■ Two trigger modes • Continuous — keeps shooting for as long as the condition stays met • Standby — shoots once, then waits until the condition is no longer met before it will shoot again Choose Standby when the situation holds steady — someone standing still, a room that stays bright — so you don't end up with a hundred of the same photo. ■ Features • Shot count (1–10; 11–100 or unlimited with Pro) • Interval Time between shots, from 0.0 to 99.9 seconds • Delay Time before the shot, from 0.0 to 99.9 seconds, with a countdown ring around the shutter button • A sound when the condition is met, so you know it noticed even from behind the camera • Automatic capture lock — the sensors keep watching, but nothing is taken • Grid (thirds / center) • Inclinometer showing side-to-side and front-to-back tilt at once, turning with the way you hold the device • Aspect ratio (default / square) • Saved size (1/4; Full and 1/2 with Pro) • Save to Photos, or with Pro to a folder on this device or in iCloud Drive • Add location • Capture review • Disable Auto-Lock, so a long session isn't cut short by the screen turning off • Front and back camera Photos are saved to the iOS Photos library — or, with Pro, to a dated folder on this device or in iCloud Drive — with what triggered the shot written into the file's EXIF. ■ Some ways to use it • Leave it by the door or in the garden and catch whoever — or whatever — turns up • Clap your hands to take the shot from across the room • Raise both arms from across the room and be in the photo yourself • Catch fireworks and lightning on brightness • Put it beside a path and shoot whatever comes within a metre • Shake the phone to shoot • Shoot when the phone faces a particular direction Open the Quick Guide from Description in Settings. It includes recipes like these. This app shows ads. The Pro in-app purchase removes them, and unlocks the Full and 1/2 sizes, saving to this device or iCloud Drive, and shot counts of 11 or more and unlimited. Without Pro, photos are saved at 1/4 size to the Photos library, and Shot Count is 1 to 10.

Keep ordinary days in one finite roll of film. filmroll diary is an iPhone video journal for quietly recording everyday light, movement, voices, and atmosphere. Create a roll with a fixed length, capture short clips in order, and develop them into one finished movie. Choosing film, shooting, playback, music, export, and watching the finished result in your private screening room are connected as one calm analog ritual. 【A finite roll】 Choose a name, recording length, and 1080p or 4K when loading a new roll. A limited duration gives each recording—and the light and sound in front of you—more meaning. 【Four original film stocks】 Choose one distinct look for each roll: ・Summer Indie 2002 Soft, warm color inspired by early-summer air and backlight ・Rainy Platform 2003 Quiet blue-green tones and low contrast reminiscent of a rainy station platform ・Autumn Letter 2004 Warm, faded red-brown color inspired by an old letter ・First Thaw 1991 Bright, delicate color reminiscent of light after thawing snow Your selected film remains consistent across the live preview, playback, thumbnails, and finished movie. 【Shoot like a film camera】 Adjust exposure and zoom, use the light, and switch between front and rear cameras. Slow shutter and silent slow motion are also available. Portrait and landscape clips remain in shooting order when developed into one movie. 【Develop with music】 Choose music that complements the film, then balance it with the original recorded sound. Finished movies can be saved to your Photo Library. 【A private screening room】 Every successful export is also preserved in the app’s screening room. Choose a movie from its film reel box and begin with a projected countdown inside a dark, empty auditorium. When the movie ends, a film-textured “Fin” card remains on the screen. Select a specific movie, start a random screening, or let continuous random screening play through your collection. Finished movies remain independent even after their original rolls are reorganized. 【A quiet film archive】 Rolls are stored on a physical shelf of metal film cans and paper records. Selecting a roll reveals five frames sampled across its complete timeline as a short filmstrip. Multiple rolls can also be selected and organized together. 【Languages】 日本語, 繁體中文, 한국어, and English 【Accessibility】 Supports VoiceOver, Dynamic Type, Reduce Motion, and state indicators that do not rely on color alone. Try filmroll diary free for30days from the first launch. After the trial, a single purchase unlocks continued access to all features. Existing rolls and completed movies are never removed when the trial ends. Passing light, fleeting movement, and the sound of that day—preserve the moments that will never return in quite the same way.
