Not that there's anything wrong with devices. However, the need for a separate device has been largely obviated by contemporary smartphones. Mobile phones in general are arguably today's main wearable technological companion. The ubiquity, portability, and convenience along with the rapidly increasing capability, customizability, and decreasing cost make these the preferred platform for everyday memory aids.
I've wondered why the work is mistaken for a physical device. Sure, it runs on a device and it would not surprise me if I've been imprecise with my words from time to time (and I probably have a recording of such gaffes :-). Perhaps the word "aid" connotes device (like "hearing aid"). I've also used the phrase "memory prosthesis," which also might imply a physical device. Or I can just blame the press since they tend to prefer pretty pictures of futuristic toys with blinking lights :-)
One of the important aspects of a successful memory aid is availability. Throughout my dissertation work, I recorded many conversations. Ironically, one of the reasons I missed recording some conversations was because I forgot to charge or carry the memory prosthesis (i.e., a prospective memory problem). But, I had my mobile phone with me nearly always. Adding another device to one's utility belt of portable gadgets along with the associated memory burden of remembering to charge it, carry it, etc. seems to be counterproductive towards the goal of improving memory. Hence, running software on your existing device is the way to go.
While I'm on the topic, I'll also mention that the memory aid is not a pill, liquid, or other late-night remedy. But, if you prefer to go that route, here's one I found. Note: I haven't tried the recipe below; if it works for you, drop me a line.
Take seven almonds and immerse them in a glass of water in the evening. Next morning, after removing the red skin, grind the almonds. Mix the ground almonds with a glass of milk and boil. When it has boiled, mix in a spoonful of ghee (clarified butter) and two spoonfuls of sugar. When it is lukewarm, drink it. Take this on an empty stomach in the morning and do not eat anything for the next two hours. Do this for 15 to 40 days.
