# TS vs TPE Amplifier

The clearest difference is device support: TPE Amplifier at 3 against TS's 1. TS's advantage is iOS requirement (9.0 vs 12.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
