Everyone carries a smartphone but hardly use it to it's fullest capacity.
My phone has become my eyes, thanks to bad vision that can't be corrected for a short time, I'm relying on the magnifying app to see everything and the camera to take pics of stuff too far away (bottom shelf, top shelf, etc.) so I can see prices, etc. It's the best real world hack around.
HOWEVER, that's not the main topic, my main topic might seem so silly and trivial yet most of you don't use it - THE CHECKLIST. I had an app called Color Notepad that let's me put in free form text or a checklist. I have several checklists for anything from just general todo lists, shopping lists, restaurants to try lists and even lists of things to do on my web sites so I don't forget as they come to me. No, I don't sit there typing all the time as I keep my general checklist open most of the time and click the voice input and just say whatever it is I want to add to the ever growing list. Now the trick is to be disciplined enough to check it before you leave the store, leave the house, etc. and make sure you got everything you came for or need to take with you.
I'm hoping someone will make a location-based reminder app that you can have remind you to check the checklist when it senses you're leaving a location, that's an app I'd buy.
I have a really good memory but even mine isn't THAT good and I'm finding I'm getting way more things accomplished and spending a lot less time doing it just using this silly checklist on the phone.
I always remember to take my pills in the morning and at night but I have one that has to be taken during the day about 3PM that I almost never remember because I'm busy doing something else and not thinking about stupid pills. The daily alarm goes off with voice now to remind me daily and it says "PILLS THREEE ZERO ZERO P M" and I pull the pill pack out of my pocket and take it. Quite amusing but it's another cyber enhancement I can't live without.
Other time saving things are my music player has an option to start playing the minute you insert the headphone jack instead of fumbling around looking for the app, clicking play, etc. It also turns down the volume automatically so you don't blow your ears or the car speakers out when you do it.
Not to mention the flash in the camera has become my go-to flashlight that I use all the time.
It's not a phone, it's a Swiss Army knife with a level, compass, ruler...
It is my lifeline, phone or cyber enhancement?
Since it's in my hand most of the time, I'm going cyber enhancement which is why I'm foaming at the mouth to get my eyes fixed so I can try Google Glass so I can quit carrying this phone around :)
