The clearest difference is in-app purchases: Pi Design at none against Star Memories's 3. Pi Design also leads on iOS requirement (15.1 vs 17.0). Star Memories's advantage is ratings volume (7 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Star Memories sells 3 in-app purchases, starting at $0.99 per month. Pi Design asks for nothing beyond the download.
