A wearable device to assist with memory that includes a processor, a haptic output device, and a button. When a wearer of the device encounters a piece of information they want to remember but thinks they may forget (e.g. the name of someone they just met; a phone number; a coupon code; an address; a new word definition, etc.) they simply press the single button on the device. The single button press initiates a pre-set schedule of tactile reminders about that piece of information. The reminders are vibrational and/or haptic outputs triggered by the processor that come quickly at first, and then become more spaced out over time. The device beneficially assists users in implementing the empirically supported ‘spaced retrieval’ memory strategy—where spaced retrieval refers to a method of retrieving information at longer and longer intervals to aid memory retention for selected pieces of information.
