Verdict
The clearest difference is in-app purchases: Basic Capital at none against OneArbitrage's 1. Basic Capital also leads on ratings volume (14 vs 2). OneArbitrage's advantage is update cadence (every 2 days vs weekly). On price, rating, ads and device support there is nothing between them.

On the App Store both sit at effectively the same score — 5.0 for Basic Capital against 5.0 for OneArbitrage. That said, the two scores are not equally well evidenced: Basic Capital has 14 ratings behind it against 2, so its average is the more settled of the two.
