I was ecstatic after I found Clear (on the App Store for my iPhone) some time ago -- finally, a great basic tasks manager for someone who just wants to make lists. I wasnt looking for scheduling, reminders, graphics, whatever -- I just wanted to make lists. Simple grocery lists, to-do lists, work lists, who-wants-what-from-ChinaEats list; whatever. It just plain worked.
And using the app couldnt be easier -- simple to create new lists, simple to check stuff off (and a touch of fun, too, in the pops and bloops for marking stuff as completed/gotten). And I always had my iPhone with me, so adding to the list was as near as my pocket.
Still, I wished I had the ability to use it on my Mac; quickly call up a list and type it there (I type worlds faster on a physical keyboard). And my wish was answered -- Clear was available for the Mac -- and it syncd between devices as well. No matter where I was, and what I was using (iPhone, Mac, iPad), I could check, mark, and update my lists, and know that they were syncd across devices. Nirvana for a list-maker.
Flash-forward to 2016: sync has been broken since last year, repeated emails to RealMac go unanswered. The "Support" link above is broken. Searching the RealMac site, youll find a Product Road Map on their blog section dated November of 2015 that says: "I dont have a timeframe for when well ship this new sync update, but I just wanted to let you know that its in the works. After weve "fixed sync", well be back to adding new features and more timely updates to Clear."
Just accept that this program has been abandoned on all platforms, and find a replacement.
