Bad broken desktop app fixed

Update - The developer posted an update for the desktop version of the app a few days ago and it did fix the issue. Yay! Its much better now. My issue is with the length of time it took. But its fixed now and i can use the app. There are still some minor styling issues and when thats resolved i have no problem giving 5 stars. It is a really nice app.

Past review - If you plan on using the desktop version of this, good luck! It broke where you cant even read certain parts of it due to styling and contrast issues and its going on two months where the developer promised a fix and nothing. They say they will fix it and never do. Paid for a subscription which I will cancel.

Great Planner

This is a great planner app for those who like the set-up of a Franklin Planner. It could be improved of course in some ways (e.g. in the level of task complexity —- sub tasks etc), but its performance overall is superb and flexible and It is easy to use! You can slide tasks around to reorder them. You can also slide a task from the task column into your schedule column. Those two abilities are a big plus for someone like myself who wants a planner to be user friendly right from the start. The app has a lot of functionality and has been well thought through. Frankly, I am surprised that it isn’t rated higher than many of the other planning apps out there. I have tried so many of them and I keep coming back to Opus One for its ease of use and performance. The developers are to be commended for their fine work!

Been waiting a long time for this!

Ever since my original iPad I’ve been looking for an app that truly replaces my old Franklin Planner. I finally have it in Opus One! It has everything I need, and I especially love the flexible daily notes. It’s clunkier on the iPhone but still usable, and I prefer iPad or Mac for bigger planning, anyway. The developer seems responsive (based on others, I haven’t needed to contact support) and I think some of the features I hope to eventually have are already on their list: better Apple Pencil integration, more customization of the Franklin Covey-type screens (compass, planner, etc.), sublists for tasks.

I have encountered one glitch I hope will be fixed ASAP—when editing a repeating event it does the opposite when I select “for this event only” or “all events.” Weird.

Thank you for bringing me back my planner!!
