# Data Structure Display vs Wealth

The clearest difference is ads: Data Structure Display at none against Wealth's shown. Data Structure Display also leads on device support (4 vs 2) and iOS requirement (13.0 vs 18.0). Wealth's advantage is update cadence (weekly vs every 5 months). On price and in-app purchases there is nothing between them.

Both are free to download. Data Structure Display sells 1 one-off in-app purchase and Wealth sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Data Structure Display ships an update every 5 months, Wealth weekly. The most recent releases landed on October 13, 2026 and October 6, 2026 respectively.
