“Took a while to understand how to make it work for me, but I got there, and this is essentially my only tool now. Love it. Would be nice to have asterisks on the cards to denote part limits in play, and would be double…”
“I cannot imagine playing Satisfactory without a calculator, this tool is beyond essential for late game”
“very useful tool! wish it had tabs so i could switch between models without having to import/export files”

“If you play Satisfactory, then this is a must have companion for it. Easy, updated, clean, you can plan all your builds quickly without much trouble. And it helps you identify huge time-wasting problems (like forgetting…”
“App is not bad for getting the gist of what you need figured out but it doesnt really work with more complex setups where you want to loop back byproducts back into the flow from what I have noticed but that is fine…”
“This is the best software ever. I used to keep track of all of my satisfactory builds and calculate them on paper and pencil. Now its so much easier, something that would have taken me hours to calculate I can now do in…”

“The de facto factory planner for Satisfactory. It has saved me so much time, it keeps getting updated, and it's free. Feels like steeling.”
“Amazing application for planning your factory. I realize you've released it as Free To Play, but you're killing your userbase by only showing one preview image with DARK MODE. Replace some of those retina searing light…”
“Fantastic Partner application for an already fantastic logistics game. Highly recommend for anyone needing help with planning as it provides a top down perspective on your builds. (Please don't start charging for it we…”

“The single best tool for Satisfactory. The only thing that would make it better would be an alternate mode for the Satisfactory Plus mod.”

“It's generally exactly what you need it to be, and accurate. However, it does lack a few features. You cannot have the program respect the map limits for resources, or set those limits for resources yourself. So for…”

“confusing at first, but once you get used to it, the modeling becomes your best friend”
“Man i started using this at like 20 hours not knowing what it did and kinda questioning why it was so popular. Coming back to it after hundreds of hours makes me regret doing all that math manually. Amazing app. Worth…”

“AMAZING tool, is so extremely helpful to plan things out, it helps tremendously, I don't think I could play the game as well as I do without it. (or at least it would take a TON more time to figure things out) Also, [b]…”
“Incredibly intuitive and easy to use. Utilizing steam for cloud saves is also very convenient. My only qualm is sometimes unexpected/inconsistent behavior when it comes to splitting outputs - but this is minimal…”

“Very useful. Some momentary clunkiness, but an extremely good planner. Recommend for anyone going phase 3 and beyond”
“Just started playing Satisfactory recently. Hooked up. Satisfactory Modeler is invaluable to prototype and plan layouts, from just a simple "Coal Power Plant" to probably the whole ecosystem of connected factories.…”

“Fantastic app! This has helped so much with planning my factories. The only thing I would like to see the Dev add is a basic text block so I can label my factories and leave notes, but even without that, it is a top tier tool.”
