From script to finished blocking. back-to-one is the blocking tool for directors and cinematographers. Import your screenplay as FDX and the app builds the project for you: every scene with its slugline, and every character. Instead of starting from scratch, you start where the work begins. SCRIPT IMPORT - Import FDX, TXT or PDF - FDX creates the project, scenes and characters automatically - Pick scenes individually, OMITTED scenes are excluded - Each scene's text laid out in proper screenplay format CANVAS AND STAGING - Top-down canvas, smooth on iPad and Mac - Place characters, cameras, lights, walls and props - Import a floor plan as a background image - Scene templates, and save your own - Large prop library, import your own PNG props - Background actor groups as a single object CAMERAS - Auto-aim: the camera turns with the character it is linked to - Field of view from focal length and sensor format (S35, FF, S16, MFT, ARRI LF, anamorphic) - Six rig types: tripod, Steadicam, handheld, drone, action cam, crane - Multi-cam setups, grouped by color - 180-degree line with a crossing-the-line warning SHOT LIST - Every camera creates a shot, linked both ways with the canvas - Shot numbers by setup (1A/1B) - A storyboard image per shot - Coverage status: open, shot, cut - Estimated shooting time per shot, with totals - Shoot day per scene, and a shoot-day filter ANIMATION - Timeline with keyframes, play, loop, speed - Characters walk to target points, facing direction per keyframe - Camera moves and orbits on smooth curves - Follow: the camera tracks a character LIGHT AND EXTERIORS - Key, fill, back, practical, HMI, Kino, reflector - Watts, dimmer, gel, diffusion, height, color temperature - Real sun position by location, date and time, with golden hour detection SET DOCUMENTS, READY TO HAND OUT - Scene PDF with plan and shot table - Lighting plot with numbered fixtures and a legend - Project overview as a PDF - Shot list as Excel and CSV - Canvas as an image ON SET - Full-screen presentation mode - Dim, night and red-light modes for a dark set PROJECTS AND COLLABORATION - iCloud sync between iPad and Mac - Share projects through iCloud sharing - Scene-level merge, auto-save, backups YOUR DATA No server of our own, no tracking, no ads.

Character, camera, light, prop, door or window: grab it in the menu, drag it onto the stage, let go — it sits exactly there. On the Mac the mouse drags right away, on iPad your finger after a short hold. The previous way (pick it in the menu, then tap the stage) is unchanged and still there. Also fixed: • The sensor format from the project settings did not stick. It was not saved reliably, not read back when opening a project, and missing from backups. Same cause, same bug: the setting carried over into the next project, and a change made on iPad never reached the Mac. • Dragging your own PNG props let the browser take over the gesture instead of keeping the object on the pointer. • On iPad the drag broke off as soon as your hand drifted up or down — the list scrolled instead of following. This affected storyboard frames from the shot list too. ### 1.4 — 2026-08-28 Now on iPhone. back-to-one now runs on iPhone, iPad and Mac — with an interface built for the phone, not a shrunken one. Plan, shot list, script and viewfinder sit where your thumb can reach them. • Room scan: where LiDAR is available, the app captures the room and turns it into a usable floor plan — as editable walls or as a background image, including doors, windows and openings. • Viewfinder: live image in the project's aspect ratio, focal-length wheel from your lens set, shutter. The frame lands on the shot of the camera you picked. • Storyboard frames on the plan: drag an image from the shot list onto the diagram — it stays where you drop it, and a thin line ties it to its camera. • Works offline: open, edit and save projects in airplane mode. iCloud catches up as soon as you are back online. • Language: the app picks up your device language on first launch, and you can switch it on any device. Plus many smaller improvements to the plan, the animation and the export. ### 1.3 — 2026-08-11 Scale, measuring, and German shot sizes • The grid has a scale. You decide how many metres one grid square stands for, and a scale bar appears at the bottom left if you want it. It is aligned to the grid — so you can count squares — and it now also travels into the PDF and the exported image, where it is most useful. • New ruler in the toolbar: tap two points, read the distance. It snaps to object centres and wall corners so the number is actually right. • Metres or feet and inches, set per project. • An imported floor plan can now be moved: switch on "Align background" in the stage panel, drag the image into place, switch the mode off again. • German shot sizes are now actually German in the German app. Two additional sizes were added to complete the ladder. • In the shot list the focal length now sits next to the shot size, and the estimated shooting time has a row of its own. • Fixed: with camera setups, the shooting times of the individual cameras were added up. Cameras in a setup shoot simultaneously, so the time belongs to the setup and is no longer counted more than once. • Fixed: exporting an image could produce black borders if you had zoomed out beforehand. • The "Movement" column is gone from the Excel, CSV and HTML exports. It only held technical abbreviations, and what the camera does is told by the camera symbols and movement paths in the plan. • The help has a new chapter "Scale & measuring" and now also covers the context menu, the zoom slider and the aspect ratio. ### 1.2 — 2026-08-08 Aspect ratio, and one stubborn click • Every project now has an aspect ratio — 2.39:1, 1.85:1, 16:9, 4:3, 1:1, or one you type in yourself. Storyboard images now appear everywhere in the frame you are actually shooting: in the shot list, in the plan PDF, on the storyboard page and in presentation mode. The framing can be shifted, and the original image is kept in full — nothing is cut away. • Fixed: dragging a slider and releasing outside the window closed that window unintentionally. This also affected selecting text in the project settings. • The settings gear is larger and easier to spot. Existing projects start at 16:9. If you shoot in a different format, set it once in the project settings. ### 1.1 — 2026-08-07 Order in large projects • Folders can now be collapsed and expanded — in the project list as well as for the scenes inside a project. A collapsed folder shows how much it holds, and the view stays the way you left it. On a series with several seasons, you only see what you are working on right now. • On iPad, storyboard images and floor plans can now be taken straight with the camera or picked from your photo library — no longer only from the Files app. A sketch from set makes it into the right shot in seconds. • The App Store listing now correctly lists the app as available in German and English. ## More apps by ERIK HAFFNER - [Believe in me!
