  • The multi-factor identification system is designed to protect digital identities and the future of cybersecurity. Rather than passwords or two-factor authorization, Woven has created a system of multi-factor identification which uses “a combination of the private key, biometrics and other factors.” When users want to share their digital identity, such as when starting a new job, they would sign it using their private key. This proves the document is authentic and that the user is who they say they are.

Top Features Of Calendar App Like Woven

Woven stands out among its competitors in the productivity space due to its distinctive features, which can be categorized into several key areas:

1. Smart Templates 

Woven has features that acknowledge meetings and events that could be categorized into different types, such as interviews, client meetings, sales meetings, lunch, coffee, etc. This feature allows users to create templates, eliminating the need to repeatedly establish the details and parameters of a meeting from scratch. Users can also add custom tags that facilitate planning, review, and analysis of the timetable using the app’s analytics.

2. Scheduling Links 

Woven’s Scheduling Links are static, one-time, public links that include the user’s availability. Invitees can simply click on the link and choose a suitable time, with the entire meeting process handled within the app. Woven also addresses a common limitation of existing scheduling tools by allowing users to create custom links for specific individuals.

3. iOS Integrations

Woven has provision for iOS integrations, including Siri Shortcuts and iMessage, making it easy to schedule events directly from iOS devices. 

4. Group Polls

Woven incorporates Group Polls, a built-in feature that allows users to quickly and easily determine the best meeting time by gathering preferences from a group of stakeholders.

5. Smart Time Finding 

Leveraging its AI capabilities, Woven considers the availability of all participants to suggest the optimal meeting time. As users continue to utilize Woven, the app became smarter and gradually relieved them of minor scheduling tasks, resulting in time savings. Its real-time analytics monitor how users spend their time, actively aiming to enhance productivity and ensuring the most effective use of time.

Steps To Create A Calendar App like Woven

Here are some essential steps to keep in mind to make an app

1. Build The Team To Plan The Project 

Establish a small team led by an experienced project manager to undertake tasks such as project initiation, scoping, and planning. The team should include a proficient software architect and a few skilled business analysts (BAs). The team’s duties should encompass gathering and managing requirements, developing technical solutions, choosing technology stacks and development tools, and project planning.

2. Identify The Requirements And Project Scope 

Finalize the project’s scope and requirements by having the BAs lead in gathering the functional requirements through detailed discussions with business stakeholders. The team should decide on the target platforms (e.g., web, Android, iOS, etc.), and the architect should define non-functional requirements (NFRs) such as usability, performance, scalability, maintainability, usability, security, etc., and review industry benchmarks. The team should draft project specifications, with the PM implementing processes such as requirements review and change management to write effective project specifications.

3. Build MVP

Plan the MVP (Minimum Viable Product) for the proposed calendar app using the Agile development methodology for iterative development. Launch an MVP with fewer features to get market feedback and validate your business ideas and assumptions. Prioritize features for the MVP and use tools such as the pain-and-gain map and prioritization matrix to help with the selection process.

4. Choose The App Platform 

Decide on the mobile app to develop – either a native Android/iOS app or a cross-platform app. Develop native Android and iOS apps using Java or Kotlin for native Android development and Swift or Objective-C for native iOS development. This programming language makes the best use of the respective operating systems and delivers the best user experience, performance, and security. Alternatively, reduce development and maintenance costs by using a web framework like React Native to develop a cross-platform app. However, cross-platform apps cannot fully match the native user experience, performance, and security.

5. Choose A Cloud Computing Platform 

Select the cloud computing platform for the project, such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. Use a Platform-as-a-Service (PaaS) platform such as AWS Elastic Beanstalk for developing the proposed web app and a Mobile-Backend-as-a-Service (MBaaS) platform such as AWS Amplify for the mobile backend. These platforms handle the cloud infrastructure, operating system, middleware, runtime environment, and various services, allowing you to focus on code and data.

6. Evaluate 3rd Party APIs 

You can determine 3rd party APIs for developing a calendar app, such as: 

  • The Google Calendar API, which helps developers integrate Google Calendar into their apps 
  • The Calendarific Global Holidays API, which provides the holiday lists of 230 countries and covers 3,000 provinces
  • Developers can use the Calendarific API to incorporate public holidays from various countries into their apps.
  • The FXCalendar API provides finance event data that can be integrated into other applications.
  • With the SuperSaaS API, online scheduling and automated reminders can be added to existing applications.
  • Nylas Cloud Calendar API offers advanced features such as scheduling and reminders, which can be integrated into various apps to improve productivity and organization.
  • Apple EventKit – Apple provides developers with tools for integrating and developing calendar apps, such as EventKit and EventKitUI, which allow easy access to calendar data and different interfaces for adding to applications.
  • Outlook calendar API by Microsoft allows access to calendars, events, and reminders on various apps. Additionally, it provides family-sharing options to make the calendar accessible to others.
  • Cronofy API allows developers to retrieve open time slots, manage tasks and synchronize calendars from different sources.
  • With 31Events API, you can invite users to events, generate event reports, and integrate with various applications.

7. Choose The Technology Stack

Identify the ideal technology stack for the web, Android, and iOS calendar apps, such as Java for native Android, Swift for native iOS, Angular or React.JS for front-end web development, Node.js for back-end development, and MySQL or PostgreSQL for RDBMS. For NoSQL databases, consider MongoDB or Apache Cassandra.

8. Decide On A Security Solution 

Formulate a robust application security solution that includes proactively mitigating key application security vulnerabilities, utilizing powerful encryption solutions, implementing “Compliance-as-Code” for security and compliance testing in the CI/CD pipeline, and employing technical solutions to secure APIs. Since the calendar app processes users’ personal information, a strong security solution is crucial.

9. Strategize The Calendar Application Development 

Consider the following when formulating your strategy:

  • Iteration planning: Employ the Scrum methodology, which facilitates the implementation of Agile projects. Organize several features into a “sprint” or iteration, and include a plan for these sprints in your project blueprint.
  • Cost estimation: Evaluate the expenses involved and formulate a budget.
  • Human resources: Outline a hiring plan.
  • Other aspects of project management: Focus on areas such as communication, quality, and risk management.

10. Assemble A Team For Development

Hire personnel with the following roles:

  • UI designers
  • Web developers
  • Native Android and iOS developers
  • Testers 
  • Idea Usher engineers

Choose to hire from a reputable software development company rather than freelance platforms. Working with part-time freelancers can be difficult, and freelance platforms do not provide any management support. Established app development companies offer full-time developers and management support, including the provision of replacements should developers leave the project mid-way. 

11. Plan The User Interface (UI) Design 

Ensure effective UI design by adhering to appropriate guidelines such as:

  • User Interface Design Guidelines for web applications
  • Material Design guidelines for Android apps
  • Human Interface Guidelines for iOS Apps

Note: Use web frameworks like Angular that offer useful UI design templates.
