Love this app!

I've been an Omnifocus user since v1 and still use it to keep track of my multiple work projects. Love its power and features, but sometimes I just want - and need - sometihing simple, especially as I'm getting a little older. My daily workflow evolved around my Mac and iPad screens in split view with Omnifocus and the Calendar app sharing the space. It worked, but I still preferred something simpler that might integrate the 2 apps.

So glad I found Opus One! It's been a blessing! Reminds me of the good old days with my FranklinCovey paper planner, down to the Compass, Mission, Values and Goals. So a huge thanks to the developers. While others might think the old planner look is a bit cheesy, I love it! And I absolutely love the Meeting tab and its features. Makes planning my day and meetings a lot easier.

One suggested feature is a Projects tab with the capability to track projects and their associated tasks. I can kinda do that now with the Goals section, but having a Projects feature would be awesome!

Opus One is Fantastic!

Opus One is unlike any other app in the productivity category. What makes it completely unique is its emphasis on life leadership rather than just project or task management. If all you’re looking for is a simple way to list your things to do, there are many lighter programs to accomplish that. But if you want a comprehensive program that does a deep dive into exploring and connecting how your life mission and personal values determine your goals and projects, and how those help to create life balance, positive motivation, and steady progress toward life success, this is the only program I have ever seen that accomplishes all that.

The structure is similar to a very popular paper organizer that includes tabs for the most important aspects of an organized life. Starting with defining mission and values, Opus One walks you through the process, step-by-step with great tutorials, so that by the time you’re finished, you have identified what’s most important to you in the various roles you play, how you want to express that through projects and goals, and how to break those down using a weekly “compass” and daily to-do’s to keep you on track to achieving a sane, balanced life.

A very reasonable yearly subscription is required to access all the features I mention above, but one fee opens the app on all devices and I have found its value in terms of increased focus and productivity well worth the price.

Best Productivity App I Have Purchased

I think I have only written one other review, but I am using this app so much that I thought I would give the team there a “shout out.” I have purchased and/or used about a dozen calendar and to-do apps over the past few years. It always seemed that something was missing in each of them—not so with Opus One. It lets me use the hybrid David Allen, Franklin Covey system I use, just like I would on paper. Syncs well with iPhone, iPad, MacMini and MaxAir. As one other reviewer mentioned, I initially had a glitch getting them all to sync, but the support team worked it out and set good information on what needed to be done and where. Unlike a lot of apps, this one has a full user manual. Although it is very easy to use, I have opened the manual (access from the Mac version) and got familiar with some of the deep functionality. I like the Eisenhower Matric and the Weekly Planner for that productivity overview I sometimes need. The only think they could add that would set my world on fire is the ability to use my Apple Pencil in the notes view on the iPad, but even there they thought things through with an icon for a date time stamp. Great app.
