# TiZo vs Optogenetics Pro

The clearest difference is ads: Optogenetics Pro at none against TiZo's shown. TiZo's advantage is update cadence (every 6 months vs every 45 months) and iOS requirement (15.6 vs 17.0). On price, in-app purchases and device support there is nothing between them.

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

TiZo ships an update every 6 months, Optogenetics Pro every 45 months. The most recent releases landed on September 28, 2026 and September 20, 2026 respectively.
