Back in the day, back to the last century, back to the past, we could carry Macs in a backpack, and long before the iPhone revolutionized personal computing, I owned, used, loved and sought after the ubiquitous, made-up from-a-day-dagplanleggeren.
You remember them, right? The big, fat, over-filled multi-ring binder day planner who recorded your entire life for posterity, minute by minute, hour by hour and day by day. Well, the days of carrying around a wooden body to take notes are gone, but not forgotten. Here is one of the smart 21st century digital day planners that you can actually use right away because it's so familiar (more so if you're old and used day planners right back in the day).
Opus Me, Opus You
One of the most popular day planner apps for Mac is Opus One. Opus One looks exactly like today's yesteryear planners, from tabs to calendars to ring binders; skeuomorphism is alive and well with Opus One. Perhaps this is a recall to the last century, and perhaps Apple's chief design hero Sir Jonny Ive deprives skeuomorphism as a plague on humanity in the 21
Here is an example. What does it look like to you?
If there is no exact copy of a planner from last year, then I am a monkey's uncle (please do not contact my relatives for confirmation of this claim). Everything you need to build a better future by taking care of the day's minutes is built into Opus One.
Set daily tasks, check status, adjust priorities in planes, add notes for each entry, get crazy with GTD (get things done) focus method, or add a blast from the past with the Eisenhower method. Opus One handles everything.
Opus One is a good Mac citizen, which means the app works fine with Apple's built-in applications, including event integration with calendar, notes that can be shared with messages, Facebook or Twitter, and you can easily enter text, maps, pictures, checklists, drawings and audio clips.
This means that Opus One is a high level of SMART goals, compass and master task lists, a mission section to set up personal task task and personal values, and even motivational quotes to help you get through a difficult day.
 Above all, I see Opus One as a day planner for your lifestyle. It's not just for business meetings and notes. It's for today, tomorrow, and your future; everything neatly organized, but infinitely flexible and adjustable, with the ability to sync Google Calendar and other Macs.
There is another weather forecast built in so you don't have to switch to another app. Opus One is like kitchen synchronization for day planners, what Franklin Day Planner would have been and should have been.
Even better, it's an Opus One for iPhone and iPad. It's good because unlike the Franklin Day Planner from a few decades ago, I don't carry my Mac around where I go. I could. But I don't.
Instead, I take the iPhone everywhere, and the iPad occasionally goes, but rarely will I empty my Mac anywhere except a trip.
What about the inevitable warnings?
To get all the features you pay a subscription price, compared to some subscriptions, the message seems to be a few dollars a month. I'm pretty sure I spent about the same on the Franklin Day Planner refills every year.
