# Sci vs Molecular Model Simulator

The clearest difference is in-app purchases: Sci at none against Molecular Model Simulator's 1. Sci also leads on ads (none vs shown). Molecular Model Simulator's advantage is update cadence (every 10 days vs every 5 weeks) and iOS requirement (11.0 vs 13.0). On price and device support there is nothing between them.

Both are free to download. Molecular Model Simulator sells 1 one-off in-app purchase. Sci asks for nothing beyond the download.

Sci ships an update every 5 weeks, Molecular Model Simulator every 10 days. The most recent releases landed on September 13, 2026 and September 8, 2026 respectively.
