# AI Caption Writer vs PostPro

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.

Both are free to download. AI Caption Writer sells 3 in-app purchases, starting at $0.99 per 7 days and PostPro sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

PostPro holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: AI Caption Writer has 50 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 83% of AI Caption Writer's written reviews are positive against 100% of PostPro's.

AI Caption Writer ships an update every 5 days, PostPro fortnightly. The most recent releases landed on September 28, 2026 and September 11, 2026 respectively.
