Your calendar might need to be synced with other popular calendars so users can view and plan their events all in one place.
If that’s the case, there are plenty of useful APIs available to use.
Chapter #2: Ways You Can Implement A Complex In-App Calendar
Let’s say you’re an app developer specializing in a line of popular paper-based productivity planners.
Here’s how you can work with complex calendar features to further enhance your mobile app project.
2.1: Managing Notes
App users need a convenient way to manage their notes on-the-go, and many apps offer insightful tools to help them do just that.
Note-taking features allow users to take, save, and share notes with ease, whether it’s for work, school, or personal use.
With calendar integration, users can associate their notes with specific events or deadlines, making it easier to stay on top of their schedule and priorities.
2.2: Digitally Merging Paper Schedules
To recognize printed, handwritten, and typed words, you can leverage optical character recognition (OCR) technology.
What is Optical Character Recognition?
This software makes use of Google Cloud Vision’s optical character recognition capability since this software recognizes event titles accurately.
Using the OCR feature, you can scan handwritten text directly into the app.
2.3: Advanced Sharing
Incorporating a calendar into your mobile app allows for the sharing of information among various groups of people.
Whether scheduling a social gathering or a crucial business event, sharing details is necessary.
Using a calendar can help coordinate schedules, especially for users managing complex schedules. It’s crucial for calendar apps and integrations to include the ability to share data with others.
Chapter #3: Use a Calendar API For Your App
You’ve likely heard the term API before, but what is it and what does it have to do with calendars?
API is short for Application Programming Interface. It’s software that lets two applications talk to each other.
When you use apps like Facebook or check the weather on your phone, you’re using APIs.
Fortunately, big companies like Apple, Google, and Microsoft all offer calendar APIs that can easily integrate with mobile apps.
3.1. Google Calendar API
The Google Calendar API is pretty powerful, so it’s no surprise that so many apps use it.
This API allows you to edit private calendars, add reminders and alerts, search for and view shared calendars in mobile and web applications, and set up notifications.
The EventKit framework on iOS and macOS allows users to access calendars, events, and reminders in real-time.
3.2 Outlook Calendar API
On phones, tablets, and desktops, the Outlook API offers access to calendars, events, reminders, and calendar groups.
Anyone can be added to Outlook.com and be given access to one another’s calendars, which is handy for teams.
Most of the leading calendar apps allow you to easily integrate them and use their features.
Here are some APIs you can choose from based on how their features match your specific needs:
- Cronofy API helps you schedule tasks, pull available hours of the day and sync third-party calendars.
- Events API allows you to send invitations and reports to users as well as integrate with other apps.
- With the SuperSaaS API you can schedule appointments, receive notifications, create reports, and even schedule payments.
- The Funambol API allows you to easily sync your calendar to the cloud as well as use it on several devices.
- Calendarific API provides public holidays for every country.
You might not even need to synchronize with any external calendars. A simple calendar with a customizable UI may be all your app needs.
In this case, you can turn your attention to open-source solutions for UI implementations.
Chapter #4: What to Look for in Open Source Calendar Libraries
4.1: Calendar Libraries For iOS
They’re highly customizable calendars offer great designs and they’re both highly praised by the developer community.
Custom cells and calendar views can easily be created using these libraries.
The UICollectionView can also be used to manage and organize an ordered collection of data items and to present them using a custom-made layout.
4.2: Open Source YACalendar by Yalantis
YACalendar is a customized iOS calendar that offers year and month views with horizontal and vertical scrolling.
Optimized for iPhone screens from the iPhone 5 to the iPhone 11, this library can run on devices from a wide range of devices.

Chapter #5: Implement these Features with Your Google Calendar
In Adobe’s 2020 Digital Trends report for leading companies, 34 percent say their customer journey is a top priority for 2020.
By investing in the customer experience, companies with $1 billion in revenue are likely to earn an extra $700 million within three years, according to the Qualtrics XM Institute.
Here are a few tips to keep you on track:
5.1: Use Attractive Aesthetics
Colors, round shapes, and shadows can be used to accomplish this.
Or you don’t have to use bright colors or unusual shapes to draw attention—a minimalist design will let users focus on the app’s features instead.
When implementing Google Calendar or other calendar APIs, it’s important to keep the style and layout of your calendar feature in-line with your users.
Keep the design simple and straightforward. Remember, calendars are meant to be easy to use and make your users’ lives simpler.
5.2: Implement an Easy-to-use Interface
The best calendars have a simple and easy-to-use interface. Not always a simple task, given all the data users can input.
Apps and APIs need to ensure a calendar integration isn’t a complex mess for users, which can lead to poor user design.
Users should be able to find what they need and create events with minimal amounts of clicks. Some tasks they should be able to perform with ease includes finding and booking appointments, sharing information with others, creating group events, and so on.
Remember, your users shouldn’t have to work hard to use your calendar feature.
5.3: Guests Can Be Tagged and Invited to Events
This is one of the many functions available with a Google Calendar integration.
You’ll also want to ensure that your app can display calendars correctly regardless of how users hold their devices, so make it responsive to changes in screen orientation.
5.4: Ensure the Hardware is Accessible
Good calendars should make use of available hardware features.
5.5: Use Speech Recognition
With today’s digital calendars, adding and editing calendar entries can be achieved with natural language.
This feature has been successfully implemented in scheduling applications like Calendar and Voice Calendar.
With that said, there are a number of apps that can also benefit from speech recognition technology besides all-in-one planners, like those for parking and healthcare.
You can use Google Assistant or the SpeechRecognizer API to implement a speech recognition feature for Android.
For iOS users, Apple’s Speech Framework comes bundled with the operating system.
For web app developers, you can use the Web Speech API.
An app that integrates a calendar doesn’t sound too complicated at first glance, but if you want to add additional features to your app or even design a completely new calendar app, it’ll take time and effort.
You can easily add a calendar into your app by following best practices and using calendar services already available on the market.
