# Unity vs Light

The clearest difference is ads: Unity at none against Light's shown. Unity also leads on monetization model (free vs ad-supported) and iOS requirement (8.0 vs 12.0). Light's advantage is update cadence (every 4 months vs every 28 months). On price, review sentiment, 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.

Unity ships an update every 28 months, Light every 4 months. The most recent releases landed on October 22, 2026 and October 16, 2026 respectively.
