Your photos already know where you have been. Stourk reads only the date and place stored with them and turns the whole collection into a journey: a stork carrying your memories across an illustrated atlas, city by city, year by year. WATCH THE JOURNEY Choose a year, or your whole life, and watch the places become a route. The map is a printed atlas, not a satellite view; the route is drawn as the shortest arc between the places your photos know. Scrub through it, jump to a moment, and see the photographs from that stop as you pass. THE POST Every city you stayed in writes to you. Its letter is addressed by hand, stamped with the city's own postage, and postmarked by the Stourk postal service. Tear one open and the city's own note comes out first, then the photographs from that city. THE PASSPORT Every country you entered is stamped into a passport: rubber ink, struck askew, dated. Turn the pages. Tilt your iPhone and the pages keep a surprise for you. THE CASE Journeys earn luggage labels. They stick to a suitcase you keep. KEEPSAKES Save a journey as a poster or a short film, and share it. PRIVATE BY DESIGN Stourk has no account, no server and no analytics. It reads photo dates and locations on your iPhone, keeps what it builds there, and never uploads a photograph or a place. Your library is read-only to it. Clear the local data whenever you like; Stourk will not read your library again until you ask. The only network traffic is the map itself, vector tiles from OpenFreeMap with data from OpenStreetMap contributors, and, for a photo that lives only in iCloud, that photo from Apple. English and Turkish.

Turn everyday photos and videos into cinematic stories. GradeLab is a color grading editor for iPhone and iPad with LUT filters, vintage looks, professional color tools and video editing, all in one app. Pick a look, dial in its strength, then make it your own. From warm portraits and moody travel clips to soft film tones and retro aesthetics, GradeLab gives you full control over the light, color and atmosphere of every edit — across the whole frame or just one part of it. CINEMATIC LUTS & VINTAGE FILTERS - Browse cinematic LUTs with live previews on your own photos and videos. - Explore signature looks like Warm Cinema, Teal Orange and Soft Film, plus a full collection of film-inspired LUTs. - Adjust look strength for a subtle finish or a bold cinematic style. - Import your own .cube LUT files and use them just like built-in looks. - Save your color grading as presets and apply them to any photo or video for a consistent style. PROFESSIONAL COLOR GRADING - Exposure, contrast, highlights, shadows, whites and blacks. - Temperature, tint, saturation and vibrance. - Eight-band HSL to shape individual colors. - Color wheels for shadows, midtones and highlights. - Color Warper: shape colors with Hue/Sat and Chroma/Luma modes. - Master, Red, Green and Blue curves. - Hue, saturation and luminance curves for precise color control. - Fade, sharpening and vignette. - Before and after comparison as you edit. MASKS & LOCAL GRADING - Grade one part of the frame instead of the whole picture. - Ellipse, rectangle, gradient and freehand masks. - Feather the edge, set the strength, or invert a mask to grade everything outside it. - Stack several masks on one clip, each with its own grade. - Track a mask to a moving subject and let it follow through the shot, forward or backward. - Use the same masks on photos. KEYFRAMED COLOR GRADING - Animate the grade itself, so a look builds through a shot or falls away at the end. - Keyframe exposure, contrast, temperature, saturation, HSL, color wheels, vignette, curves, film effects and look strength. - Adjust any keyframe by hand, including motion created by mask tracking. TRANSITIONS - 45 transitions between clips: dissolves, dips, wipes, slides, zooms, blur dissolve, whip pan, film burn, glitch, prism, page turn and more. - Set the duration of every transition on the timeline. FILM EFFECTS - Film grain, bloom, glow and halation for an authentic analog feel. PROFESSIONAL SCOPES - Histogram, waveform, RGB parade and vectorscope for accurate grading. APPLE LOG, HDR & PRORES - Grade Apple Log and Apple Log 2 footage, plus HLG HDR video. - Apple Log 2 from iPhone 17 Pro uses its own wide-gamut transform, never Apple Log's. - Export ProRes 422 and ProRes 422 HQ on compatible devices. - Export in 4K or your source resolution, with custom frame rate and bitrate. EDIT VIDEO & PHOTOS - Trim and split clips, change playback speed, and add titles and audio. - Grade photos with the same color tools you use for video. - Export photos as full-resolution JPEG, HEIC or lossless PNG. - No watermarks on your exports. TEXT, LAYERS & MOTION - Add titles with curated font families or your own imported TTF fonts. - Layer overlays with blend modes. - Mask a layer with an ellipse, rectangle or split line so the track underneath shows through. - Feather or invert a layer mask, and keyframe it into a wipe or reveal. - Animate text, transforms and color grading with keyframes. Whether you're grading a travel vlog, a short film or a single portrait, GradeLab helps you create a look that's unmistakably yours. Feature and format availability depend on your source media and device capabilities. Some features require a subscription or one-time purchase.
