I tried out one of the CareKit apps this morning (I think the first four were released today) and they&#x27;re really nice. Very simple, good use of notifications to remind the user to take pills&#x2F;add progress, and they&#x27;re still useful even if your doctor isn&#x27;t signed up.<p>I wonder why Apple is the only big company doing something like this? It just seems like a really great idea and I&#x27;m surprised Google for example hasn&#x27;t got in on it (that I know of).
