The ease of use, personalized color codes, simplicity, immediate sync with smartphone, detection of events in email, and easily editable schedule with drag-and-drop ability to move appointments. Also the ability to enter a phone number and website info to link and call directly from the appointment, as well as the ability to add an attachment to view during the appointment. The creation of a "quick event" is convenient too - as well as auto-fill on events that happen on a regular basis. It's almost as if it learns from your past meetings and understands what you're trying to accomplish. Review collected by and hosted on G2.com.

The reminder setting could be easier to complete, but overall it's not that big of a deal. The fact that it has reminders for any option of time and multiple reminders is great and well worth the complication that's easy to get used to. Also being color blind - it's slightly difficult to distinguish between the current month showing, and the next month as it's minimal difference. A slightly more drastic color change to distinguish between the two would be greatly appreciated and would allow less constant squinting. Review collected by and hosted on G2.com.

Alerts, I would miss many meetings without alerts on all devices. Review collected by and hosted on G2.com.

Manually having to enter details from an outlook cal from a P/T job. Review collected by and hosted on G2.com.

I like the fact that I can put something on my iCal on any of my Apple devices and it automatically syncs to my other devices. The look of the calendar is clean and simple. The variety of colors available so that different calendars can be color coded. Review collected by and hosted on G2.com.

Every now and then I get an error message because I allowed an event to expire before I added it to my calendar. It takes me quite some time to figure out how to remove that error message. I checked the apple community first but I was still unable to get rid of the error message. Review collected by and hosted on G2.com.

iCal is very easy to use, synchronizes with all Apple devices, which is very helpful if you are using mostly Apple products. Graphic and interface design is very pretty, you can use different colors to organize events. If it's a repeating event, like a birthday or anniversary you can make the event for each year. In a work environment if everybody has iOS you can create an event for each person in the team. Review collected by and hosted on G2.com.

If you don't have an Apple product you cannot use it, also if you have an iPhone but not a MacBook, the calendar won't sync. Review collected by and hosted on G2.com.

I like that iCal combines my personal calendar with my work calendar so I can see everything in a more holistic manner. Review collected by and hosted on G2.com.

Sometimes events get added to my calendar that I didn't add. For example, a dinner reminder that was mentioned in a text message will show up. This could be beneficial though, for those who do plan something and forget to add the actual reminder. Review collected by and hosted on G2.com.

I used iCal for most of my high school and college years, and now that I'm a working professional, it's proving to be as useful as ever. Over the years, I've tried many calendar, scheduling and organization apps, and none of them have compared to the seamless interface and simplicity of iCal. I love that I'm able to use iCal on all of my Apple devices — it makes it easy to transition from home to the workplace while keeping everything in one place.

I have noticed that iCal isn't quite as customizable as other calendar apps, which I think it in keeping with most Apple products and applications. Sometimes, I wish I was able to integrate other apps — other than Microsoft Exchange — into my calendar. Review collected by and hosted on G2.com.

I love that it lets me keep track of schedule. I can input doctors appointments, meetings, PT conferences, birthdays. Plus, I love that I can sync it to social media. Review collected by and hosted on G2.com.

Nothing, I have no complaints. It is a fantastic app. Review collected by and hosted on G2.com.

I really enjoy that you can have multiple calendars linked to one. With each email (personal and work) I am able to see what my whole day looks like. I also like that I can invite my family to a calendar and make sure we are all on the same schedule when needed. Review collected by and hosted on G2.com.

I wish the design/set up of the monthly calendar was a little easier to navigate and organize. I have a lot scheduled so just having a dot on the day doesn’t tell me enough in the preview. Review collected by and hosted on G2.com.

I can say without a doubt that iCal is absolutely essential for college students who like to stay organized and involved on campus. I've used iCal since high school to schedule my classes, plan meetings, and block out my days in a way that's optimized for productivity. I love the feature on iCal that allows users to color-code calendars — it was perfect for distinguishing classes from meetings and personal activities. Review collected by and hosted on G2.com.

If anything, I wish iCal was more like Outlook and gave users the ability to invite others to events. I'm able to accept invitations from my Apple email, but to my knowledge, I can't use iCal to send meeting/event invites to other students and colleagues. I'll always prefer iCal to Outlook for everyday use, but when it comes to work and school, I do miss the collaborative function. Review collected by and hosted on G2.com.
