# Lystra vs nu

The clearest difference is device support: nu at 3 against Lystra's 1. nu also leads on iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Lystra sells 2 in-app purchases, starting at $0.39 per 7 days and nu sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
