I have been using this app very heavily for over three years. My schedule changes constantly throughout the day and the ability to make quick changes and customize reminders is invaluable. The ability to set recurring appointments based on any criteria needed is priceless, which is why I purchased WeekCal to begin with. Customizing different views in portrait or landscape is very useful. This app does what it is supposed to and lots more, if you take the time to learn it, which can be done as you use it. It is highly customizable to the way I work, syncs with iCal and the developers are constantly improving the app. The only time a glitch has occurred is when Apple "upgrades" iOS and those minor glitches have always been addressed by the developers. Developers are good about responding to questions and making updates/changes based on user feedback. Even though there may be minor functions that I would prefer to have my way, I understand that developers need to satisfy the majority of users and it is not fair to negatively review the app for that reason because this is absolutely the most reliable and flexible app that I have ever purchased. Its value far exceeds the small price. About the only thing that I would put on my wish list as a future feature request is a well integrated task list and project list and I would gladly pay an upgrade charge for those features, even as add-ons that are accessible from each function. Then I would give this program 10 stars! I cant imagine getting through my day without this terrific app. BTW, I never write reviews but these developers have more than delivered a super high quality app at a very fair price for this product and I gave been very impressed. Thanks WeekCal... You keep me on schedule every day.
