Compatible with select Android and iOS devices, Octaland 4D+ is the first in a series that will expand into houses, vehicles, and more, making it a comprehensive educational tool.

Minimum system requirements include Android 5 or iOS 11.0+, Qualcomm processors, 1 GB RAM, and a 5 MP camera. Not compatible with some older devices like certain Asus and Lenovo models.

- App fails to install, start, or stay open on several devices (black screen, forced close, crashes)
- Device registration limit and reset problems; users can't register a new phone or receive codes by email
