# Derivative vs Nodal

The clearest difference is in-app purchases: Derivative at none against Nodal's 1. Nodal's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Nodal sells 1 one-off in-app purchase. Derivative asks for nothing beyond the download.
