Verdict
The clearest difference is rating: ReadySub at 2.0 against Swing Subs's 1.7. ReadySub also leads on ratings volume (136 vs 23) and iOS requirement (12.0 vs 15.0). Swing Subs's advantage is update cadence (every 2 months vs every 5 months). On price, review sentiment, ads and in-app purchases there is nothing between them.
