This is a question all app developers get asked, along with how much does web app development cost.

We’ve already covered some related question in our previous articles:

Nonetheless, we made a dedicated article for this question, because it’s very difficult to answer how many hours it will take to develop a web app at early stages. The reasons why it’s difficult to predict timing is because it very depends on answers what goes into making a web app.

Apps are bespoke pieces of software, each different and individual. You get simple apps and complex apps. Some web apps can use few functions and be little different from a website. And some apps carry inside lots of functions, just like these web apps made with AngularJS.

You can ask us to build a web page that displays data or another one that access camera, GPS, support social media functions and so on.

The average timing for development of web application

Yet, there are industry researches (100 development companies participating) and our humble experience that allows us to give you more specific numbers.

On average it takes 4.5 months to build a front-end app and a backend infrastructure.

But here’s more detailed breakdown, based on our experience.

  • 2-3 months for a simple web app like an information-based app with the database back-end.
  • 3-6 months for a complex app with social media functions, in-app purchases, logins, favorites, back-end admin panel.
  • 6+ months for a very complex app with a dedicated analytics, unique functionality, trading option, visualization patterns, etc.

That said there are areas of process to watch out for. Intricacies where time and budget for a web app can take far too much time and become costly. Like with all projects without proper planning and risk mitigation development can go on and on, resulting in a boogie low-quality app.

How to save time and budget during web app development?

boring negotiations of web dev

It all starts with the requirement gathering phase or Discovery phase. We recommend you this article it will help understand how to save your time negotiating with developers. If the requirements are noted down well you have the opportunity to prevent misunderstandings and future problems. It forms the basis of the time estimation and costs.

Poor requirements can lead to a bad planning. Thus it may also affect the time required to write down detailed software specification requirements for the app.

On top of that, please keep in mind all the changes that you make want to add to the development. Changes in the development mean changes after the code is written forcing developers to go back to their work, which has a large potential for introducing bugs.

In addition, we advocate for thorough testing plan and QA practices. Proper testing practices are invaluable, they help find problems early, which save a lot of time on the delivery phase. The ideal situation is to thoroughly test your web app and send detailed organized feedback to the development team.

Summary: How long to build a Website App? A typical website will take 16 weeks at a minimum from start to launch. This includes 4 weeks discovery, 3 weeks design, 3 weeks design revisions, 3 weeks initial development, and 3 weeks of modifications.

Bottom Line

At the end of the day, all the best practices we’ve covered so far turn out to be worthless without good communication. Flawless and regular communication between all parties makes the project run smoothly.  It’s important to share the same vision and avoid misunderstandings. At GBKSOFT we strive for good planning and communication with our clients. All it takes from you is to contact us and consider web app developed.
