# Monte Carlo Pi vs Physics Constants Library

The clearest difference is in-app purchases: Monte Carlo Pi at none against Physics Constants Library's 1. Monte Carlo Pi also leads on ads (none vs shown) and iOS requirement (15.0 vs 18.4). Physics Constants Library's advantage is update cadence (every 7 months vs every 22 months). On price and device support there is nothing between them.

Both are free to download. Physics Constants Library sells 1 one-off in-app purchase. Monte Carlo Pi asks for nothing beyond the download.

Monte Carlo Pi ships an update every 22 months, Physics Constants Library every 7 months. The most recent releases landed on October 16, 2026 and October 22, 2026 respectively.
