Factory Ledger for Factorio

Plan a Factorio production line from the first miner to the finished item. Factory Ledger is an independent calculator and reference for iPhone and iPad.

BUILD A WORKING LINE
Choose from 323 recipes and 43 production modules. Set your output per minute, then follow a connected material map and a checkable construction plan. See which machines to place, what recipe to set, the inputs each step needs and where its output goes.

INCLUDE YOUR RAW MATERIALS
See rounded drill counts for supported ores. Choose burner, electric or big mining drills and set mining productivity. Include coal demand for supported burner drills and furnaces, plus uranium-mining acid where applicable. Each supply card keeps the required rate and equipment together.

PLAN BELTS AND BATCHES
Size belt lanes for material rates and review bottlenecks. Turn a finite crafting request into whole batches, subtract ingredients already in storage and check off what remains to collect.

KEEP YOUR FACTORY PLANS
Save lines, notes, completed construction steps, mining settings and favorites. Explore research references and supported Space Age recipes. Export and import JSON copies through Files. A guided starter line helps you learn the workflow.

No account, advertisements, analytics or tracking. Planning works offline.

Calculations assume steady inputs and normal quality. Mining, machine and fuel assumptions are shown in the app. Modules, beacons, a full power simulation, spoilage and physical belt routing are not modeled. Batch tickets cover direct deterministic solid ingredients.
