To the Editor: Prescription medication cost has been on the rise in the United States, outpacing inflation and increasing medication nonadherence. Mobile applications and discount programs have arisen in response to this problem, but limited data exists regarding whether these entities actually reduce costs, whether cost savings are similar across entities, or whether cost savings are consistent over time. This observational cost analysis assessed 3 prominent mobile medication applications: GoodRx, Blink Health, and SingleCare. One of the authors of the study created a list of 21 of his most commonly prescribed dermatologic medications (Table I). The lowest price of each medication was researched on the 3 applications on May 10, 2017, and then again on June 10, 2017. Prices that could only be obtained by paying for a membership in a pharmacy chain’s discount program were excluded. The pricing of the 21 medications from the 3 applications on May 10, 2017, and June 10, 2017, alongwith the overall GoodRxpricing analysis, can be found inTables I and II.Not a singlemedicationhadan
