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 into make our engine the most modern, fast, small, clean, and flexible calendaring system for iOS. The results are the new Ulti-Planner. This allows for flexibility and expansion into the future.


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(in Calendars in the Settings or just using a filter), and also Apple has a setting in Calendar in the main Settings app that is called ’Sync’ that can hide older events from you.

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

The Ultimate in Organization. Your calendar evolved.

Needing more energy ,

Love it!

I can actually read what’s on my calendar instead of seeing little dots. And I share it with all of my family members so everyone can see each other’s events.

Poor layout and design

I’ve been using xtreme agenda (same author) for years and I absolutely love it. It is one of the few apps I actually paid to upgrade. I got a notice that this is the replacement for XA so I installed it.

No, thank you.

The interface is awful. The XA interface has a large calendar space and is very easy to read. I would need to use a magnifying glass with this crowded mess 100% of the time for it to be of any use to me. I’ll hang with XA a little longer.

Developer Response ,

Thanks for giving it a try. And thanks for contacting us directly after writing this review. We hope the explanation that we gave you about how to configure the equivalent of your Extreme Agenda screen in Ulti-Planner for your iPhone 7S helped you. We have made a change in version 1.01 to help that even more. The app is fully configurable so no customer should ever need to stay in a mode that is cluttered or requires a magnifying glass.

We invite you to stay using Extreme Agenda, as it isn't going away.

Clean and easy

Very nice and clean easy to read UI that integrates calendars and reminders together.
Not overflowing with options that make your head spin. Just a simple easy to use app with a lot of good features.
