Distributed practice and retrieval practice have strong research support. Quiet wakeful rest has encouraging but mixed evidence across settings. Hidden randomized timing is an experimental product hypothesis and is not claimed to be scientifically proven superior to fixed study schedules. Experimental 432 Hz, 528 Hz, and soft 40 Hz modulation options carry no medical, therapeutic, healing, or guaranteed memory-enhancement claims.
