# AWS Wickr vs Rack Builder Pro

The clearest difference is price: AWS Wickr at Free against Rack Builder Pro's $0.99. AWS Wickr also leads on rating (4.7 vs 4.3) and ratings volume (2.3K vs 27). Rack Builder Pro's advantage is review sentiment (69% vs 46%) and chart position (#44 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

AWS Wickr is free to download; Rack Builder Pro costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

AWS Wickr holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: AWS Wickr has 2.3K ratings behind it against 27, so its average is the more settled of the two. Written reviews complicate that: 46% of AWS Wickr's written reviews are positive against 69% of Rack Builder Pro's, so the app with the better star average is not the one people write more warmly about.

AWS Wickr ships an update every 4 weeks, Rack Builder Pro every 2 weeks. The most recent releases landed on September 26, 2026 and September 28, 2026 respectively.
