# SBF Theorie vs Xylopedia

The clearest difference is in-app purchases: Xylopedia at none against SBF Theorie's 10. Xylopedia also leads on ads (none vs shown) and iOS requirement (15.0 vs 18.6). On price and device support there is nothing between them.

Both are free to download. SBF Theorie sells 10 one-off in-app purchases. Xylopedia asks for nothing beyond the download.
