Building a weather app like 1Weather

create a weather app

It’s time to understand the steps to build a weather app like 1Weather, and these are as follows:

1. Assemble your project planning team

1Weather offers all its features in its free version, and the premium version eliminates ads. This should tell you how competitive the market for weather apps is!

If you want your weather app to stand out, you need to plan the development project well. Start with inducting a competent project manager (PM), an IT architect, and a team of business analysts.

2. Define the scope of the project

This team should discuss with the business stakeholders to gather the business requirements, subsequently, you should define the project scope. I recommend that you offer an Android and an iOS app with features similar to 1Weather, targeting an English-speaking audience. You also need a website to market the app.

3. Identify the right PM methodology

You can launch a “Minimum Viable Product” (MVP) with the above features, subsequently, you can add more features based on market feedback. Agile, a popular methodology that supports iterative development of this kind fits the bill for this project, as I have explained in “Waterfall vs Agile: which methodology is right for your project”.

4. Pay heed to app internationalization guidelines

While supporting an English-speaking audience initially, you could support more languages in the future. Your design and development should factor in app internationalization guidelines for this, e.g., you should keep your code separate from the content. Read more about app internationalization in “The ultimate guide to mobile app internationalization”.

5. Formulate an effective development approach

I recommend that you zero in on an effective development approach consisting of the following:

  • Design a website for online marketing using WordPress, the popular open-source content management system (CMS).
  • Use a managed cloud services platform so that you don’t need to manage IT infrastructure.
  • Develop native mobile apps for Android and iOS since they offer the best user experience, security, and performance.
  • Utilize software development kits (SDKs) and application programming interfaces (APIs) to expedite the project.
  • Use a mobile device lab on the cloud to test against a wide range of mobile devices.

Such an approach improves the chances of project success, as I had explained in “What is the best development approach to guarantee the success of your app?”.

6. Build the complete project team

You now need to induct the following roles to build a complete project team:

  • UI designers;
  • Android developers with Java skill;
  • iOS programmers with Objective-C skill;
  • Testers;
  • DevOps engineers.

Creating a weather app involves a good deal of coding and testing, therefore, you should plan to induct a field expert development team. Read more about it in “Freelance app development team vs. field expert software development teams”.

7. Organize the team using the “Scrum” technique

“Scrum” is a time-tested technique to manage Agile projects, and I recommend that you organize your team as a “Scrum team”. Such teams work as follows:

  • The PM performs the role of a “Scrum master” and builds cross-functional teams where developers and testers work together.
  • A “Product owner” provides business requirements in a document named the “Product Backlog”.
  • The team estimates the requirements and schedules them in “Sprints”, i.e., iterations, using a process called the “Sprint planning”.
  • Scrum teams hold “Daily stand-up meetings” to discuss the project status.
  • Business stakeholders review the app in a “Sprint review meeting”, and approves the sprint if the app works.
  • The team also conducts “Sprint retrospective meetings” to learn lessons from sprints they complete.

Read more about Scrum in “How to build a Scrum development team?”. You ought to find an effective PM tool to manage these activities effectively, and I recommend Trello.

8. Find the right WordPress theme

A great WordPress theme suitable for marketing mobile apps will give a professional look & feel to your website, therefore, I recommend that you use “Jevelin multi-purpose premium responsive WordPress theme”.

This theme is fully responsive, moreover, it features a powerful drag-and-drop content editor. You can find the theme documentation on its website.

To implement the eCommerce feature, you should use the WooCommerce WordPress plugin. It’s easy to configure, and its website provides comprehensive documentation.

9. Sign-up for the appropriate managed cloud services

Signing-up with the right managed cloud services provider saves you time since you don’t need to manage the IT infrastructure. For hosting the WordPress site, I recommend that you use Amazon Lightsail. Lightsail offers secure and reliable WordPress hosting, moreover, you can use a “Virtual Private Server” (VPS).

You can use the same AWS account and host your mobile backend on AWS Amplify. Amplify is the Mobile-Backend-as-a-Service (MBaaS) offering from AWS, and it offers the following advantages:

  • It handles the cloud infrastructure, persistent storage, etc., therefore, you don’t need to build and manage the mobile backend.
  • You will find it easy to implement features like security, user management, and push notifications when using Amplify.
  • Amplify helps you to scale your mobile app, furthermore, you can easily integrate 3rd party APIs with your code.

10. Find a mobile device lab on cloud

Your Android and iOS apps should work on all available Android and iOS devices, respectively. You need to test your app against a wide range of devices to ensure this.

Find a cloud services provider that offers mobile devices for testing. I recommend pCloudy since it offers over 5,000 device-browser combinations on the cloud.

11. Sign-up for a suitable weather data API solution

Your development project will benefit from using a weather data API solution, therefore, I recommend that you sign-up with OpenWeatherMap. The Weather API solutions from OpenWeatherMap offer many advantages, e.g.:

  • It offers current weather data for over 200,000 cities. This data is collected from over 40,000 weather stations.
  • There are APIs that historical weather data, weather maps, etc.
  • This API can provide hourly forecast.
  • OpenWeatherMap API solutions offer daily weather forecasts, and it’s available for 16 days at any location or city.
  • Other APIs from the same company provides climate forecast for 30 days and 5 days.
  • The data is available in common formats like JSON, XML, etc.
  • You can use its bulk downloading feature.
  • The company claims to provide data with high accuracy.
  • OpenWeatherMap provides comprehensive documentation for all of its APIs, and you can access them on its website.

Read the OpenWeatherMap “Price” page for its pricing plans.

12. Get an eCommerce API solution

You can use an eCommerce API solution to easily implement the in-app purchase feature, therefore, I recommend that you use Shopify. You can use its API solution as follows:

13. Procure a payment gateway API solution

The app users might want to upgrade to the premium version, alternatively, they could use the in-app purchase feature. Both require a payment gateway integration, therefore, I recommend that you use a suitable API solution.

Braintree offers a robust solution, and it’s from PayPal. You can use its “Braintree Direct” solution, and the following documentation can be helpful:

14. Find a bulk SMS API solution to implement the “push notifications” feature

The proposed Android and iOS apps need the “push notifications” feature, and you should consider using a bulk SMS API solution to implement this. Consider signing up with Twilio.

The “Programmable SMS” offering from Twilio is a robust bulk SMS API solution. You can read “Messaging services and Copilot” to learn how to use it. Before you buy it, check out the Twilio pricing page.

15. Designing the WordPress site and the mobile app UI

The proposed WordPress site and mobile apps need user-friendly UI. For this, you need to ensure the following:

  • The UI design team should review the Jevelin theme documentation thoroughly, which should help you to get a well-designed WordPress site.
  • iOS app UI design should conform with the “Human Interface Guidelines”, therefore, the UI design team should follow it.
  • The team should use the “Material design” guidelines to design the Android app UI.

16. Code, test, and publish the Android app

You can now develop the proposed weather app for Android, which involves the following:

  • Use Java to code it since most Android developers are familiar with it.
  • Android Studio is the preferred IDE for Android development, therefore, you should use it.
  • Integrate the OpenWeatherMap, Twilio, Braintree Direct, and Shopify APIs with your code.
  • Use the pCloudy mobile device lab and Espresso to test the app.
  • Read “Publish your app” for guidance to publish the app to Google Play.

17. Developing the iOS app

The next step involves coding, testing, and publishing the iOS app. You need to do the following:

  • Code the app using Objective-C, a feature-rich language that many iOS developers know well.
  • Use Xcode, the popular IDE for iOS development.
  • You need to integrate the APIs for OpenWeatherMap, Braintree Direct, Shopify, and Twilio.
  • Use XCTest and the pCloudy mobile device lab to test the app.
  • Publish the app to the Apple App Store by using the instructions in “Submit your apps to the App Store”.

Congratulations! You have developed the MVP of your weather app.
