# Fourier App vs EigenAlpha

The clearest difference is in-app purchases: Fourier App at none against EigenAlpha's 1. Fourier App also leads on iOS requirement (13.0 vs 26.2). EigenAlpha's advantage is ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. EigenAlpha sells 1 one-off in-app purchase. Fourier App asks for nothing beyond the download.
