Many people, such as designers, developers, and QA testers, are employed by mobile app development companies in forward-thinking London. They have access to a professional team to assist you, no matter the stage you’re at with your mobile app overall.

Going with a freelancer in London and asking them to build you an app will mean there’s no fixed rate that you’ll pay. The skills they have and the software they’re familiar with will greatly affect the costs of hiring an app developer in the area.

iOS developers familiar with Foundation, UIKit, and Cocoa will expect higher prices. Equally, Android developers who can use Ionic, Corona, and Material Foundation will set higher rates–the more tools they can use, the higher the cost.

Obtaining a custom quote from a London app development company before you set off on your development journey is a wise move. But, yes, how do you go about choosing the right one?

How to choose the top London app developers

To choose the best app developer in London, you first need to investigate the mobile app developers available. From there, you’ll need to set up interviews with them and find out about their skills and experience while they learn about your business and mobile app objectives.

During the investigation phase, it’s best to consider the following critical areas below.

Check the portfolio

Check the apps developers have built for their customers and ask them to show you examples of their best work. Focus on apps they have created in the same area you want your chosen app to be in.

Look out for smart user interfaces; this will indicate how much the developer concentrates on the all-important user experience.

Review client references

Ask for references from earlier clients and look for app developers who provide customer contact information so you can get feedback.

Consider the following factors when doing this:

• The past brands they have served
• The challenges they have overcome
• The tech they have used 
• How well they worked in the past
• The level of client satisfaction

Previous client priorities

London app development companies will have expertise with particular types of customers. Some, for example, may only work with startups, while others might prefer larger organizations (or favour enterprise businesses altogether).

Check an app developer’s site to see what types of organizations they generally work with overall–ask these questions directly to determine how well they will work with your company in the future.

Future app support

Work with a developer that can ensure the proper support when you need to update or alter your app; long-term support for a mobile app is paramount, and you will need it.

You need to verify if your favoured London app developer will help you after launching the app. Also, consider their policy on post-release bug fixing and any formal agreements they may have.

Cost

Remember that cost and quality are always in a conflict of interest; you still need high-quality apps to get delivered at affordable rates (depending on your budget).

If a company is well-recognized and has achieved broad acceptance, then the cost of its services will be relatively high. Consider that mobile apps are a key driver of growth for the future, and balance that out with what you would reasonably expect to pay.

App delivery time

Your chosen app development company must be able to develop quality apps at a fast pace or with a reasonable turnaround time. The app needs to impact the market quickly, as this boosts your ROI.

It’s best to find out the timeframes before committing–this can save you from a nasty shock if an app developer comes back to you with a lengthy development period.
