# SmarterNoise Pro vs WHY Salon

The clearest difference is in-app purchases: WHY Salon at none against SmarterNoise Pro's 4. SmarterNoise Pro's advantage is device support and iOS requirement (12.0 vs 16.0). On price there is nothing between them.

Both are free to download. SmarterNoise Pro sells 4 one-off in-app purchases. WHY Salon asks for nothing beyond the download.
