Step-by-Step Guide to Develop Calendar Mobile App

We all are well-acquainted with an eminent adage, “There just aren’t enough hours in the day,” and there is no qualm over its extant. There’s a decent possibility you’ve said this at some point during the day. We don’t have much free time because meetings, emails, and instant messages always come at us. Time management has transmuted into an empire of apps, software, and hardware whose sole purpose is to help you make the most of every minute you spend at work.

Even though headlines say that mobile devices are deflecting and make masses more conceivably to be workaholics, 70% of individuals in a survey about mobile productivity said that their mobile devices either improve their work-life balance or have no effect on it at all.

45% of people who work from their phones or tablets say they use five or more apps to help them do their jobs better. 

Since you always have your cell phone with you, why not use it to help you instead of hurt you?

Developing a calendar app from scratch is a censorious venture. Let’s discuss making a functional, constructive, and operative calendar app. Also, we’ll talk about the most important tools, technologies, and features you’ll need to build or integrate a calendar app. 

How To Create A Calendar App?

If you live your life according to a calendar, you will work less and accomplish more. In 2023, as daily routines begin to return to normal and people begin to perform their jobs away from home, the necessity to correct disrupted workdays becomes acutely apparent.

The best calendar apps in 2023 do more than keep track of the dates; they also help you organize and simplify other aspects of your life. They assist you in proactively managing the loose ends in your calendar, allowing you to replace those management tasks with productive habits. Therefore, let’s identify the most appropriate approach to developing a calendar app for you, one that resolves your concerns with timing, productivity, or forgetfulness in a thorough manner. 

Create a Calendar App in 10 Steps

If you already have an app concept, you’re good to go. Proceed to the next stage!

1. The Project Should Be Initiated and Planned by An Adroit Team

An accomplished team should handle project inception, scoping, and planning activities. This team should be led by an experienced project manager (PM). You’ll need a skilled software architect and a few business analysts (BAs).

2. Set the Scope and Requirements of The Project 

By defining the scope and requirements, one can ensure that the project’s scope and requirements are accurately defined and mapped, allowing project managers to allocate the necessary labor and costs to complete the project. You must decide on the target platforms, such as the web, Android, iOS, etc. The project manager must put processes based on project specifications, such as requirements review and change management.

3. PLAN the MVP 

An MVP is a development method in mobile app development that involves developing only the core functionalities to solve a specific problem and satisfy early adopters. An MVP is essentially the basic model of your product that will achieve the primary goal you want to achieve. It would be best if you started with devising an MVP (Minimum Viable Product) for your project.

4. Select from a Native, Android/IOS, or a Cross-platform app 

Choose the type of mobile app to create. You have two choices: native apps or cross-platform apps. For native Android development, you will use either Java or Kotlin. On the other hand, Swift or Objective-C will be used for native iOS development.

5. Identify a Cloud Computing Platform 

For your project, select a cloud computing platform. Cloud computing is used in mobile cloud computing to deliver applications to mobile devices. These mobile apps can be remotely deployed using speed, flexibility, and development tools. Using cloud services, mobile cloud applications can be quickly built or revised. You can use Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform.

6. Evaluate Third Party APIs for the Calendar App 

 Third parties provide third-party APIs — typically companies like Facebook, Twitter, or Google — that allow you to access and use their functionality through JavaScript on your site.

7. Select the Technology Stack 

• Java: For native Android development, use this feature-rich and secure programming language.
• Back-end development with Node.js: For back-end development, you can use Node.js, a popular JavaScript-based runtime environment.
• MySQL or PostgreSQL: If you need an RDBMS, these open-source SQL databases are excellent choices (Relational Database Management System).
• MongoDB and Apache Cassandra: These are two open-source NoSQL databases that can help you build scalable and performant applications.

8. Hire a Team 

It would be best if you filled the following positions:

• Designers of user interfaces
• Web designers
• Native iOS and Android developers
• Testers
• Engineers in DevOps

9. Design the User Interface (UI)

User Interface (UI) Design anticipates what users may need to do and ensures that the interface contains simple elements to access, understand, and use to facilitate those actions. UI combines aspects of interaction design, visual design, and information architecture.

10. Supervise the process 

It is critical to monitor the status of your project as it progresses actively, evaluating potential roadblocks and making necessary changes.

Building Blocks of Calendar App Development 

The following is a list of some helpful guidelines that can be used to design calendar apps that cater to your particular requirements in the most appropriate manner.

1. User Experience as Well as User Interface

When developing an app, whether it be a calendar app or another kind of app, the thing that is most crucial is to give a compelling user interface and an interactive user experience. Leverage UI/UX design services. When the user first accesses the app, they should not experience any difficulties while moving through the app, and the user interface should be kept as simple as possible while yet being appealing. In the contemporary climate, the usage of simplistic forms and vivid colors has become increasingly prevalent. Consider the example of the Dribble app.

2. The Ability to Synchronize Events or Processes

A single program can be used by a user on numerous devices in today’s world, including a mobile phone, tablet, desktop computer, iPad, and so on. Therefore, it is essential to regularly synchronize the app’s data in order to ensure that the user does not experience any difficulties. It is also preferable if the data are synchronized with cloud services since this eliminates any possibility of the user accidentally deleting important information.

3. Superior Capabilities, Functions, and Features

It is necessary to incorporate sophisticated features and functionalities into your app if you want it to stand out from the crowd and go beyond the norm. You can make it more user-friendly by providing a color scheme for users to select, various modes of viewing, and the ability to add reminders from within the app. enabling users to participate in events through the app, etc.

4. Access to The Hardware

Utilize the hardware of the device in order to increase the safety of your application. The application may, for instance, make use of Apple’s 3D Touch or Force Touch. Additionally, geographical information can be included in the events if you so choose. Research and preparation are necessary steps in the process of developing a calendar app. The functionality of an app can be improved in a variety of different ways. Employing a mobile application development business that specializes in the field can help you create an app that is unique and innovative.

Industries That Require an In-App Calendar

1. Education 

The colossal scope of the industry has been engulfed by online education. Education platforms favored integrating calendars to make their services more practical and convenient, especially amid the COVID-19 pandemic. A built-in calendar enables users to arrange lectures, homework, Q&A sessions, and other activities in a sedulous way. The calendar within the application reminds users of all alerts and notifications. Whether it be a deadline for submitting an assignment or a test reminder, the planners will assist in accomplishing this duty as quickly as possible in a student’s hectic schedule, which necessitates clear and precise planning to achieve success. The flexibility, functionality, and adaptability of the calendar applications allow you to tailor its capabilities to your specific needs and requirements, which not only helps the planning process for the student but also improves the efficiency of the learning process.

2. Logistics

In the logistics business, calendars are used in many different ways, and they let you schedule shipping, order updates, and delivery. One app that has a calendar built right into it is Uber Freight. There are some exciting things about it. The shipper and the carrier can look at their past and future shipments. Also, it lets you choose the date and time for the deliveries. Also, the development of calendar apps in this area.

3. Healthcare

Healthcare is another field that has thought about using in-app calendars for different reasons. You can make an appointment with a doctor using the app’s calendar. Also, it reminds you when to take your medicine. You can also set up a training session for a particular day and track your physical activities to get the correct statistics. Real-time calendar sync with healthcare apps lets users make doctor’s appointments, plan when to take medicine, set a reminder for regular checkups, etc. The user can also see if event invitations have been accepted, turned down, or moved. This simple appointment booking with reminders helps healthcare professionals stop people from not showing up or canceling at the last minute. In this way, the healthcare field has used the calendar in the app.

4. Transportation and Parking

Since I had trouble booking a cab, the transportation industry has given in-app integration much thought. But there could be a lot of customers like me who forced a business to add the feature. So, setting up a ride is no longer just a dream. Users can now set up a ride for a specific time and date. Also, when the ride is given to the driver, they would get a reminder. In a parking app, users can find a place to park by using the in-app calendar to book a date and time.

5. Travel 

There are a lot of travel apps that have a calendar built right in. They show users the dates when they can book flights or hotels. There are calendar apps built into many tourism and hospitality platforms. They can add times, businesses, and reminders for the most critical events and keep everyone in the family or group in the loop.

6. Platforms for Online Streaming

Users can watch live interviews, scheduled broadcasts, chat shows, and much more on online streaming platforms. People who use OTT services like Netflix or Amazon Prime must sign up for the premiere calendar, so they don’t miss their favorite shows.

7. Social Media Platforms

People use social media platforms to talk to each other and book events in real life. Social media has a whole new dimension, including conferences, group meetings, seminars, and concerts. The user can be told when the event will happen through social media. Here, people can also plan occasions like birthdays, anniversaries, and other parties. 

All the uses listed above clearly demonstrate that the calendar is more than just a way to find the date and time; it has become an integral part of our assiduous and diligent lives at every stage.

2. Syncing Appointments

Appointments will be easier to track if your devices and web apps can work together. This is perfect for companies that have shared databases.

3. Sharing Schedules via Calendars 

It helps companies align work activities without having to text, email, or call whenever a schedule changes. Just look at each other’s schedules and pick a time that works for everyone.

4. Switch Between Calendars and Lists 

You can switch between calendars and lists and bring events from another calendar app into your app. Sort tasks by their due dates and filter them in a list. There are some reasons why you might want to do this. For example, you might use Google Calendar but want to switch to your calendar app.

5. Contacts’ Availability

When planning an event, the online calendar helps determine who can come and when. Hosts can easily send event invitations with many dates and times to those who are invited. The application would quickly turn the replies into an event, so there would be no need to call, text, or email back and forth.

6. View Notifications

From new bookings and cancellations to new members in a meet, you can look at all activities important to users from the moment they start using the app.

7. Sync Your Calendar with Other Calendars (cross-Platform Synchronization ) 

Cross-platform synchronization lets you sync your calendar with other calendars, like Google Calendars, iCal, Outlook, etc. Using advanced search, you can see your team’s work and deadlines.

8. Mark Vital Events 

Mark important events, see what days and weeks are important, and keep track of events you don’t want to miss.

9. Collaborative Schedule/support for Different Time Zones

Collaboration schedules and support for different time zones are essential for teams or resources that work in different time zones but are spread out. A “collaborative calendar” is another name for this feature.

10. Drag and Drop Events 

This makes it easy to move events from one group to another without adding them by hand.

11. View Days, Weeks, and Months’ Schedules 

You can switch between different modes, such as a single day, weekly, or monthly plan.

12. Recurring Events 

Scrums are often recurring events where clients want to find out what’s happening every day, week, or month. In these situations, online calendars help plan a meeting or event that happens more than once.

13. Event Scheduling 

Sometimes, planning an event or activity is the hardest part of scheduling it. Some smart calendar apps have features for planning events that automatically pull information from the sentences you type. This smart meeting scheduler cuts down on time it takes to plan an event and set a date and time.

14. Time Block

Time Block is an excellent example of a calendar app that can help you get more done. Plan when you will work on meaningful projects to finish them in these time blocks. It shows how businesses are doing, so no one should mess with them now.

15. Embedding and Sharing 

Calendar apps with features for sharing and embedding make it easy to customize your schedule before you share it with the public.

16. Importing and Exporting 

Most calendar apps that let you import and export from other calendars also let you subscribe to specific calendars. Subscribe to a close coworker’s calendar so you can find out what they have coming up. Even events from calendars you subscribe to can be imported and exported. Just import the calendars you want as files, sit back, and you’ll start receiving alerts about their events.
