For anyone who wants a Factorio-like on iOS, there's a great game called Builderment. It's not as complex as Factorio but it does get rather involved. Works well with touch and even works well on the smaller screens of iPhones.

I was going to check it out, but IAPs are full of gem packs, which is not very encouraging. How is the freemium aspect?

Sorry for the late reply. It works fine for free. There's no impediments to the actual gameplay. Gems aren't mandatory for anything. It's been a while since I last played, but when I did, gems weren't needed for anything other than random decorative items.
