FLIM is a disposable camera you share with your friends. Start a roll for the birthday, the trip, the night out, and everyone shoots into it. Nobody sees a frame until the whole roll reveals at once, twelve hours after it started, not even the person who took it. The waiting is what makes the reveal worth showing up for. Shots you take for yourself land in your Darkroom right away. FLIM is invite-only. You join with a code from a friend, so everyone you meet here is someone a friend chose to let in. Real film feel. Every photo gets FLIM's film look baked in at capture: warm color, fine grain where film puts it, and the soft red glow real film gives a bright window or a streetlight. No filters. No sliders. One look, applied the moment you shoot, the same for everyone. Share a photo and it goes out with the orange date stamp burned in, as a print, a story, or the full frame. Every roll you are in is yours to save, all of it. Rolls for your people. Start a shared roll with up to 50 friends and shoot into it together. Everyone's photos land in the same place, and the whole roll develops at once. Trips, parties, nights out, all revealed together. Watch a roll fill up as its reveal gets closer, with a countdown on your lock screen, then play it back one shot at a time. Near-identical shots stack, a frame that came out black or blurred is marked so the call is yours, and once you have watched a reveal it stays watched on any phone you sign into. Join with an invite code, comment on each other's photos, react with emojis. When the reveal ends, start another with the same group in one tap; everyone gets an invitation they can decline. A roll's code even gets a friend who is not on FLIM yet in, with the roll ready to shoot into. Chapters. On the first of every month, the month you shared arrives on your page as a cover. It plays like a reveal, fifteen frames picked on your phone, and ends on the month in numbers: your most reacted shot, your biggest fan, the hour you shoot at. You decide which numbers other people see. Every past month is already there, and any month can be shared as a contact sheet. A feed that's yours. Follow friends, see what they post, react and comment. Your photographs are seen by the people who follow you, and nobody else. Mention someone with @ to bring them into it. FLIM is invite-only, so everyone you see is someone a friend chose to let in. The friend who invited you is named before you join, and you follow them from the start. Find friends by who you already know: people who follow you, people in your rolls, the people your inviter brought in. No public like counts. No algorithm deciding what you look at. No strangers. FEATURES • One film look, applied at capture, no post-processing • Twelve hour development window, with a roll's shots revealing together • Shared rolls with up to 50 members, joined by invite code • A reveal that plays your roll back one shot at a time, with a lock screen countdown • Chapters: every month you shared, as a playable recap with the month in numbers • Exports with the date stamp burned in: print, story, or full frame • A private feed from the people you follow, and friend suggestions that say why • Reactions, comments, and @mentions on photos and posts • Photo tagging you can edit any time, and you can untag yourself from anything • Blocking and reporting, reviewed within 24 hours • One daily notification rounding up what friends posted, instead of one per photo • Email sign-in with a one time code, invite only • Dynamic Type up to the largest accessibility sizes, VoiceOver labels throughout You need an invite to join.

Knurl is a camera for people who would rather develop the photo themselves. It captures true Bayer RAW: the sensor's own mosaic, written straight to a DNG with none of the computational photography that normally happens on the way. No multi-frame fusion, no tone curve, no sharpening. What lands in your library is undeveloped data with all of its latitude intact, ready for Lightroom or Photos to interpret however you like. THE CONTROLS ARE THE POINT A mode wheel you turn, with the real designations: P for program, Tv for shutter priority, Sv for ISO priority, M for full manual. Every position clicks. ISO and shutter move in thirds of a stop along the standard photographic ladders, on a dial that detents at every rung. Whole stops click harder than thirds, so you can count them by feel without looking. The ends of each ladder are the sensor's genuine limits rather than round numbers, which means base ISO, the cleanest the sensor gets, is actually reachable. Exposure compensation on its own scale, in thirds, with a firmer detent at zero. In manual it becomes the meter, because compensation has nothing left to act on when both controls are already fixed. An AF/MF switch and a focus ring you turn like a ring: relative, so touching it never jumps focus, and marked near to far rather than in invented distances. Three lenses, each at its native focal length, read from the hardware. HONEST ABOUT ITSELF Bayer RAW is 12 MP and does not permit zoom. The 48 MP path would mean Apple ProRAW, which is demosaiced and partially processed, so Knurl does not offer it. When the exposure you have asked for is not achievable, it says so rather than pretending. Your shots go to a Knurl album you can browse in the app, pinch to zoom, and swipe through. Volume buttons fire the shutter. Add the Control to your Action Button, Lock Screen or Control Center to open it without unlocking.
