# Optical Simulator vs Veda

The clearest difference is in-app purchases: Optical Simulator at none against Veda's 1. Optical Simulator also leads on iOS requirement (11.0 vs 15.0). Veda's advantage is update cadence (every 3 weeks vs every 4 months). On price, ads and device support there is nothing between them.

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

Optical Simulator ships an update every 4 months, Veda every 3 weeks. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
