# Spark VPN vs Nerd AI

The clearest difference is review sentiment: Nerd AI at 100% against Spark VPN's 28%. Nerd AI also leads on monetization model (free with in-app purchases vs subscription). Spark VPN's advantage is ads (none vs shown) and iOS requirement (11.0 vs 15.0). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Spark VPN sells 8 in-app purchases, starting at $7.99 per 7 days and Nerd AI sells 10 in-app purchases, starting at $2.29 per 7 days. Whichever you choose, the download price is not the number that matters.
