# Zeno vs Eira

The clearest difference is in-app purchases: Eira at none against Zeno's 3. Zeno's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 26.0). On price and ads there is nothing between them.

Both are free to download. Zeno sells 3 one-off in-app purchases. Eira asks for nothing beyond the download.
