Your project will be rewarded with a better allocation of resources and timely delivery of work by the developers when you choose the right one for your requirements.

Agile methodology is commonly used for app development. Almost 71% of organizations are reported to be using agile methodology, at least part of the time.

Agile frameworks like scrum allow developers to work as small cross-functional teams. There are daily standups and weekly scrum meetings to review the project’s progress. 

Learn more about using a scrum framework for your app development in our blog post on the topic.

Design a Mobile App Interface

An intuitive and easy-to-use user interface is a critical part of construction apps. Users should be able to navigate the app and perform complex calculations through readable fonts and themes. 

Your UX/UI designers should be able to use design tools like Marvel and Invision to build app mockup templates efficiently.

Develop a Minimum Viable Product

Now, your app developers can start building the core functionalities of the construction calculator app. Software engineers nowadays follow a minimum viable product approach while developing complex apps.

A minimum viable product contains all the essential functionalities of the desired software product. The MVP is released in the user market. The user’s feedback on the app’s features lets the development team build a product according to the user’s needs.

Billion-dollar companies like Amazon and Spotify use the MVP approach. They save a fortune in the development, testing, and marketing of a product as a result.

To build an MVP version of a construction calculator, your software developers need to have the following technical expertise.

Mobile Application Development

The mobile user market is expanding rapidly. 97% of Americans now own a smartphone of some kind. A mobile app also presents innovative marketing opportunities.

There are two options to build a construction calculator mobile app; a native app or a hybrid app.

Native Mobile App:
