Apptivus

Apptivus is an indie game studio run by solo developer Aaron Geisler. Games are built from scratch — no Unity or Unreal — using the in-house Pine Engine. The result is software that is lightweight and accessible to gamers on modest hardware and devices like the Steam Deck.

Founded in 2013. Products have been featured on the App Store, Kickstarter, and Steam.
