Ulti-Planner is the culmination of over 20 years experience in building mobile calendar and organizer apps. The original Ulti-Planner was conceived in 2004 on Windows Mobile. We have since made top level productivity apps including Extreme Agenda and The Grid Calendar, with great success. We have taken that experience and put over 1200 hours in to make our engine the most modern, fast, small, clean, and flexible calendaring system for iOS. The results are the new Ulti-Planner.


We are known for our technical support so contact us directly from within the app in the settings with any issues you may have. Or explore our website for answers you may want on how things work. A question that does come up a lot, is people think that our app is responsible for Apple Event data disappearing. Please check that you just don’t have the data filtered out but more importantly Apple has a setting in Calendar in the main Settings app that is called ’Sync’ that can hide older events from you.

Note that for some of the advanced features like icons, lists, and hashtags, info will be added to your event and reminder notes in order to save and sync this info.

The Ultimate in Organization. Your calendar evolved.

The best calendar app

The new version has a more sophisticated look than the previous one. I like this calendar because it allows you to use emojis so that you can tell at a glance what your schedule is. You can also have a detailed month view vs the little dots on Apple’s calendar which tells you nothing. It’s frustrating that a smart company like Apple can’t see that this view is useless. Ulti-planner also shows a detailed day view. There’s no other calendar apps that does this as brilliantly as Ulti-planner. And I’ve looked at dozens. The developer is also very responsive to correcting some glitches in the early software version

Seems Nice, But…

*** Thanks for your response. • You wanted to know about the glitch in Extreme Calendar. So I have written up a description of it and will post it as an Extreme Calendar review (it is somewhat difficult to describe so hopefully you will be able to understand what I am trying to convey). ***

I was excited when I discovered Extreme Calendar and eventually got the paid version. It was great in many ways and I used it for years. However, it stopped being updated long before it was replaced, despite at least one troublesome glitch that should have been addressed years ago. Now there is Ulti-Planner (nice name!) which, while also pretty nice (as far as I can tell from the free version), requires you to pay for several features that came free with Extreme Calendar, and has a one-time paid version that is almost twice as expensive as Extreme Calendar’s paid version was. I have considered biting the bullet and paying for this new calendar as well. However, my experience with Extreme Calendar made a memorable impression and I really have to wonder whether, in time, regular updates for this calendar (or any updates at all) stop coming as well. That is a real concern with any app as expensive as this.

Developer Response ,

Thanks for giving it a try and for the support of Extreme Calendar. We would love to have heard what the “glitch” was as we still do maintain the Extreme line of products, but settled into a very stable build to slow down with while focusing more on this. *Update: Thanks for following through with the report, it has already been fixed internally and will go out in an Extreme update in the coming weeks.

The cheap one time purchase model is a problem all developers face, and while we are glad you used and enjoyed it “for years” for one cheap price, in the end it doesn’t keep the lights on.

We hope that with real support and revenue we can continue to support this and grow and evolve our whole line. We already have completed a big update for UP that will add contacts along with over 100 fixes and enhancements, and have a cool roadmap planned that this new enhanced code base allows us to do, that the Extreme line made much harder(a lot of that code is over 13 years old).

Just a small point, I would think our company is the exact opposite of your concern, as the Extreme apps came out in 2010, and are extremely stable and yet still getting a small update now. So if you are expecting all apps to last 13 years with full support for one small one time purchase, I'd like to think you would re-think your expectations on the app world. We are kind of the exception...

Thanks again.

Clean, easy & useful

Ultimate-Planner is a terrific calendar and planner app with a pleasing UI. Keeping track of events, appointments and reminders/tasks is a breeze. The ability to easily create calendar filters in order to view individual categories (for example, medical appointments) without interference from other scheduled items is truly useful. All in all, I am very pleased with Ulti-Planner. So much so that I purchased the pro version. YMMV, of course. Apps are such a personal thing, and what works for one might not for another.
