# Brain Code vs Not Not 2

Brain Code and Not Not 2 both sit at 4.6 stars, but that hides the real split: 77% of Brain Code's written reviews are positive against 51% of Not Not 2's. Brain Code also leads on ratings volume (1K vs 80). Not Not 2's advantage is update cadence (every 2 weeks vs monthly) and iOS requirement (13.0 vs 15.0).
