Google Calendar

I can be online anywhtand make a appointment and it automatically save it to my google calendar.

I have no bad review at all. Have to be the best product I ever used.

With a very simple to use, but so many advanced features, and it's awesome cross-platform integration and Google's G-Suite access, planning a schedule for me at least has become very easy and simple.

With all access to google platform and linking all the Google data in one place, makes this app one of the most productive, despite it being called a calendar app, it has almost every kind of service you need on your schedule, which is why I have nothing to complain about Google Calendar.

One good thing about Google calendar is that it usually comes with the operating system in almost all Android devices and you don't need to download it from anywhere to have it. It also has a very easy user interface. On Android, you can view the calendar in a month view, week view, three day, one day or just the schedules view.

Google calendar has a flawless integration with gmail.
It reminds you of the birthdays of people in your contact list and every appointment connected to your account. This feature works like a charm.

It can be synced across all your devices and every little thing you do on one device gets updated on all the other devices straight away.

Recurring activities can be set on desired intervals like daily, weekly, monthly or annually.

Each activity can be colored according to personal wish for quick identification. This is a helpful feature especially when you have several reminders of different categories, and at the same time, it adds beauty to the app.

If you've navigated to a different month on the calendar, say to view some appointments or birthdays, and you want to go back to current date, there is a dot on the top right corner, adjacent to the menu button, clicking it will take you to the current date

The interface, despite being easy to use, it lacks some graphic beauty. It would be good to make it more colorful.
Calendar widget on android doesn't look much appealing. It would look better to add a transparency feature to it.

It has all the functions that you would expect from a calendar. And some more - reminders via text message (which is wonderful for some events), push notifications on mobile and desktop, recurring events etc.

I am using both Google Cal, iCal and Oulook calendar. The cross-ontegration between those 3 doesn not always work properly - some data tends to be missing and sometimes I get too many notifications at the same time. I know that it is all possible for editing and setting it up right, but there is never enough time to manage it properly. That's why I feel like it could be more user friendly and help me manage it so I don't get 4 same push messages at the same time.
