# Optogenetics Pro vs Pupil Detection

The clearest difference is ads: Optogenetics Pro at none against Pupil Detection's shown. Optogenetics Pro also leads on device support (3 vs 1). Pupil Detection's advantage is update cadence (every 2 weeks vs every 45 months). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Optogenetics Pro ships an update every 45 months, Pupil Detection every 2 weeks. The most recent releases landed on November 1, 2026 and November 4, 2026 respectively.
