Verdict
The clearest difference is review sentiment: Openferry at 67% against OASA's 14%. Openferry also leads on rating (4.6 vs 2.5) and ratings volume (162 vs 4). OASA's advantage is monetization model (free vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.
