Verdict
The clearest difference is rating: PostPro at 5.0 against AI Caption Writer's 4.6. PostPro also leads on review sentiment (100% vs 83%) and iOS requirement (13.0 vs 15.0). AI Caption Writer's advantage is update cadence (every 5 days vs fortnightly) and ratings volume (50 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.
