Factory Ledger for Factorio

Plan your next Factorio factory with visual production diagrams, animated layout examples and an interactive research navigator. Factory Ledger is an independent companion for iPhone and iPad. SEE YOUR PRODUCTION LINE Choose from 323 recipes and 43 production modules. Set your output per minute and explore connected supply and machine nodes. Follow material routes, inspect production requirements and use the construction checklist while building. LEARN WITH ANIMATED LAYOUTS Explore a four-furnace smelter, the 3:2 copper-cable and electronic-circuit ratio, and two-lane belt transport. Reveal belts, machines and material flow step by step, then open the matching production plan. Pause animation at any time. MAP YOUR RESEARCH GOAL Choose a technology and see its full base-game prerequisite graph. Track completed research, find available next steps and open production plans for unlocked recipes. Shared prerequisites are counted once. SIZE YOUR FACTORY Calculate machines, supported mining drills, coal demand, belt capacity and finite crafting batches. Configure alternate recipes, external supplies, mining productivity and supported Space Age production. KEEP YOUR PLANS Save lines, notes, construction progress and research progress on your device. Export and import production plans through Files. Planning works offline. No account or advertising. Optional usage analytics can be disabled in Guide. Calculations assume normal quality, steady supply and clear outputs. Modules, beacons, full power simulation, spoilage and automatic physical belt routing are outside the calculation scope. Research stages show prerequisite depth rather than estimated completion time. Layouts are original learning guides. Independent companion, not affiliated with or endorsed by Wube Software.
