# CheckBAC Enterprise vs i

The clearest difference is rating: i at 4.0 against CheckBAC Enterprise's 2.1. i also leads on review sentiment (67% vs 27%) and update cadence (every 3 weeks vs every 2 months). CheckBAC Enterprise's advantage is ratings volume (22 vs 4) and iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
