Factory Ledger for Factorio

About

Plan your next Factorio production line with Factory Ledger, an independent calculator and reference for iPhone and iPad. CALCULATE YOUR FACTORY Browse 323 recipes or start with 43 editable production modules covering science, electronics, materials, chemistry and supported Space Age manufacturing. Set a target rate, choose machines and explore the ingredient chain. See exact utilization, rounded machine counts, external supplies and co-products. ORGANIZE YOUR BELT BUS Estimate belt capacity and the parallel runs needed for your planned throughput. Include intermediate products when you want to understand more of the line. PREPARE A BATCH TICKET Turn a finite request into whole crafting batches. Enter the ingredients you already own, see what remains to collect and check supplies off as you gather them. Save your ticket for later. SAVE AND REUSE YOUR PLANS Keep production lines, notes and favorites locally. Browse research references. Export and import JSON copies through Files without replacing existing plans. No account, advertising or tracking. Planning works offline. Supported machine productivity and recipe surface conditions are included where stated. Factory calculations assume steady inputs and normal quality. Modules, beacons, research bonuses, spoilage, mining, fuel and a full logistics or power simulation are outside the model. Batch tickets cover direct, deterministic solid ingredients; they do not recursively plan an entire factory.
