FFT excels at quickly detecting abnormal signals (e.g., AFib) in the frequency domain, making it primarily used in everyday healthcare products like the Apple Watch Series 9, Fitbit Sense 2, and QardioCore.

On the other hand, wavelet transform simultaneously analyzes time and frequency, resulting in higher QRS detection accuracy, making it suitable for medical and precision monitoring devices like the Samsung Galaxy Watch 6, BioBeat BB-613, and Zio XT Patch.
