FAQ on finding the right mobile app development agency

Some of the common questions people ask while looking for an agency

How much does an app development cost?

It depends on the number of features. Simple features like push notifications, reviews, and login, tend to be cheaper. Complex features, such as payment systems, web portals, and integration with native features, increase the final cost. Based on different sources, app development may cost from 20'000 USD and up to 200'000 USD and more.

Question: How does the app development process usually go? What's the right approach?

Answer: Nowadays, having a mobile application proves to be a necessity even for businesses mostly considered to operate “offline”. When I see an ad for a service like local food delivery or cleaning, for example, I habitually go to the App Store or Google Play without even checking to see if the company has a website.

Having an app creates the perception of a more user-centric service; one that provides helpful features like in-app chat support. These features add speed and convenience to the overall customer experience. Apps also provide a platform for real reviews from user reviews which helps potential users decipher whether or not the service is worthy and validated.

For those just considering creating the first app for their business, it's worth understanding what the steps are for the development process. At my current app development agency, we’ve followed this process many times and I can testify that it is essential to adhere to it if you want to avoid expending tons of resources only to end up with a product that doesn’t match your end goals.

Here are the steps to follow:

1. Figure out business goals for the app

First and foremost, it’s crucial to understand why you need the app and what users will be able to do with it. For example, a satellite app for an offline business can serve as a tool to deliver the latest news, be a platform for your users to communicate with each other or your employees, an online shop to make orders or something entirely different and new. You have to set the goals correctly and make sure your users actually need the app so that your app helps your business and doesn’t’ hinder it in any way. It might be a good idea to involve potential users even at the earliest stage to pitch your app idea and see if they have an interest. After all, you don’t want to waste time developing something people won’t use. You can read more about this process in the articles regarding lean startup methodology.

2. Create the app design

This one is straightforward, although it’s worth noting that design also includes working on user experience (UX). This means you need to find a specialist capable of thoroughly thinking through the way people are going to use the app to make sure that the user interface (UI) is easy to navigate and user-friendly. This designer should be familiar with iOS or Android Human Interface Guidelines.

3. Implement the app

This step is what most people consider to be the “app development”. Careful not to rush into this phase in an effort to ‘just get it done’. Without defined goals and a strong, user-friendly design, the end-result might be underwhelming.

It’s not enough to just hire a good developer (unless he or she is also a great business analyst capable of going through the entire process themselves). An app needs to be well integrated into the business processes. Earlier in my career as a freelance developer, I encountered several customers who had been developing an app independently of the goals of the business as a whole. As a result, they developed an inferior product that was not widely adopted.

Once business owners realize the importance of a mobile app development process, they will most likely agree to go through the entire ideation & design process from scratch just to make sure that the final product is something customers actually use.

Question: How to choose an app development company?

Answer: Since mobile app development is a very big investment, make sure the agency size, location and expertise fits you. And what’s even more important, the understanding of your business goal is very clear. Once you did your due diligence, next step is to have a discovery phase with the chosen company. Usually it is a couple of weeks project that includes requirements gathering, creating the project plan, resource allocation plan and other preparatory work that shows the roadmap of the future development work along with an estimate. Based on that you can decide if the final project will meet your business goals and expectations.

Question: What are the main geographical locations of the best agencies?

Answer: The tech world today is getting more and more globalized, and lots of key players are becoming remote-friendly. It is related to both their employees, contractors and external agencies they hire. Location makes a much smaller difference now. However, lots of mobile app development agencies gathered in the main tech hubs and big developed cities of North America (San Francisco, New York, Los Angeles, Seattle, Austin, Portland, Boston), UK (London, Manchester), Canada (Vancouver, Toronto), Australia (Sydney, Melbourne) and Western European cities like Berlin, Amsterdam, and Paris.
