# CompositesAI vs Engineering Materials for Exam

The clearest difference is in-app purchases: CompositesAI at none against Engineering Materials for Exam's 10. Engineering Materials for Exam's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Engineering Materials for Exam sells 10 one-off in-app purchases. CompositesAI asks for nothing beyond the download.
