Verdict
3D Brain and NinerEngage+ both sit at 3.6 stars, but that hides the real split: 75% of 3D Brain's written reviews are positive against 33% of NinerEngage+'s. 3D Brain also leads on ratings volume (146 vs 9) and iOS requirement (6.0 vs 13.4). NinerEngage+'s advantage is in-app purchases (none vs 1) and update cadence (every 3 weeks vs every 2 months). On price, rating, ads and device support there is nothing between them.
