# Algorithms HQ vs Population Simulator

The clearest difference is in-app purchases: Algorithms HQ at none against Population Simulator's 1. Algorithms HQ also leads on ads (none vs shown). Population Simulator's advantage is update cadence (every 7 months vs every 16 months) and device support (3 vs 1). On price and iOS requirement there is nothing between them.

Both are free to download. Population Simulator sells 1 one-off in-app purchase. Algorithms HQ asks for nothing beyond the download.

Algorithms HQ ships an update every 16 months, Population Simulator every 7 months. The most recent releases landed on September 24, 2026 and October 5, 2026 respectively.
