About

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 iPhone, iPad and Mac - Place characters, cameras, lights, walls and props - or drag them straight from the menu onto the stage - Room scan: on LiDAR devices the app captures walls, doors and windows and turns them into a usable floor plan - Import a floor plan as a background image - Scene templates, and save your own - 146 props at true size - furniture, tableware and decor, animals, vehicles, film gear - each drawn in its own material, and the material switches off for plain outlines - Import your own PNG props - Background actor groups as a single object - Copy the walls and openings of one scene into another 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 - Camera icon size adjustable, setup number large on the label or in the body - Multi-cam setups, grouped by color - 180-degree line with a crossing-the-line warning - Viewfinder: live image in the project's aspect ratio, focal-length wheel, shutter - the frame lands on the shot of the camera you picked SHOT LIST - Every camera creates a shot, linked both ways with the canvas - Shot numbers by setup (1A/1B) - A storyboard image per shot - drop it on the plan too, tied to its camera - Coverage status: open, shot, cut - also visible on the plan, as a tick or cross on camera and storyboard - 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 waypoints, facing direction per keyframe - Camera moves and orbits on smooth curves, dolly track drawn on the plan - 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 - also as a compact one-pager per scene - 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 - Works offline: open, edit and save in airplane mode, iCloud catches up when you are back online PROJECTS AND COLLABORATION - iCloud sync between iPhone, iPad and Mac - Share projects through iCloud sharing - Scene-level merge, auto-save, backups, duplicate whole projects - Colour labels per scene, with a filter - shared along with the project YOUR DATA No server of our own, no tracking, no ads.

What's New in back

1.10

October 15, 2026

The plan now tells you more, without opening the list. SHOT AND CUT, RIGHT ON THE PLAN Anything shot carries a green tick, anything cut a red cross — on the camera and on the storyboard. Both have a dark outline, so they stay legible on any background, and they always sit at the back of the camera, never in front of the lens. THE CAMERA ICONS DO AS YOU SAY They now grow with the scale of the plan, like figures and furniture — and under Stage ▸ View you set their size anywhere between 70 and 200 per cent. The setup number sits large in front of the camera name ("1A · OTS Caty") or fills the body; either can be switched off. STORYBOARDS WITH AN ADDRESS The boxes on the plan carry what gets called on set above, and the technical line below — "[50 mm · OS]". On a restrained panel, so they read on a light stage too. Also: • Fixed: on a full-circle orbit the camera's setup number disappeared. • Fixed: the number inside the camera body was tiny and touched the edge at some angles. • The ruler is now black on a light stage instead of brownish.
