# Thread Fever vs Load Zone

The clearest difference is in-app purchases: Load Zone at none against Thread Fever's 16. Thread Fever's advantage is device support and iOS requirement (13.0 vs 15.0). On price there is nothing between them.

Both are free to download. Thread Fever sells 16 one-off in-app purchases. Load Zone asks for nothing beyond the download.
