American Red Cross


The world's first blood tracking app

How can we transform the blood donation process to tackle declining donations? This was the challenge behind Blood Donor, an app we brought to life with The American Red Cross to let donation centres manage appointments, users track their donations and communities send alerts for urgently required blood types.

Let's talk about what's next...

Need a mobile app development company? Congrats you’re in the right place. Now hit that button and tell us more.

Are you wondering how to choose a mobile app development company?

You’ve got a great idea and decided you want a top app development agency, but the process can seem daunting. Where the heck do you start?

3 Sided Cube is the UK’s top-ranked app development company. You can check our reviews on Clutch the app development supplier review portal. We’ve built apps that have had millions of users, generated millions of dollars in revenue and been number one in the app stores across the world. So, clearly, we want you to choose us!

However, doing your due diligence is vital. To make it easier we’ve curated nine important questions you should ask an app development agency before hiring them.

Selecting the right developer for your mobile app project can depend on a variety of factors: cost, chemistry, location and process are just a few we’d suggest you explore. We’ve made a playlist on our YouTube channel to help make the shortlisting decision easier for you.

Should you develop an app for Android, iOS or both platforms?

We’ve never recommended both to ‘tick all the boxes’.

The war between Android and iOS is years in the making, and with no sign of a peace-treaty any time soon, picking a platform to develop your mobile app for can be a challenge. The brands that get the decision right are the ones who understand it’s made by your audience.

Our team look at each platform on an individual basis, weighing the pro’s and con’s of Android and iOS mobile app development in relation to your specific goals.

How much does an app cost?

We’ve never compromised quality to hit a tight budget or timeline.

To be honest, we are by no means a cheap agency, but as the old saying goes, you get what you pay for (App Agency of the Year, 2017 & 2018. Hashtag just saying). Which is why we work smarter, not harder, to achieve your goals in the most cost-effective way possible.

Our team plan payment milestones at the very beginning of any project we work on, setting expectations from the get-go and estimating the cost of app development projects based on the features and functionality that add the most value to your business and end users.

Our app development process

1. Design Kickoff

Once you’ve decided upon your feature-set and your app’s MVP (Minimum Viable Product) with our strategy team, our creatives craft your mobile app designs. Every interaction, tap, pinch and swipe is designed to ensure your project achieves its goal.

2. Rapid Prototyping

Our Android and iOS developers figure out the best way to build any given solution. Core app features & functionality are developed into a live prototype, that we can then test for bugs, usability and validating technical elements.

3. Test & Iterate

This includes a number of different tests from automated virtual environments to focus-groups with users in the real world. We iterate features and functionality based on insights from ourselves, your team and your end-users.

4. Deliver

Deploying to the App Stores involves submitting apps for review, both the Apple App Store and the Google Play Store have a different reviewing process, this usually only takes a couple of days, but should be considered in your app development project timeline.

How long does it take to develop an app?

Rome wasn’t built in a day, and neither are apps. But, give us a few days and we can have a working prototype for you.

Mobile app development projects can take anywhere up to six months to complete and for good reason, rushing design sprints and development stages will almost always extend app development timelines with updates and bug fixes after you’ve launched your app in the Store.

Our team understand that great mobile solutions aren’t always the quickest, whether it’s researching your brand or testing with your users, we don’t develop Android or iOS apps quickly to ‘tick all the boxes’ if our team think there’s a better way of doing things.

Meet our mobile app development team

We’ve been developing mobile apps since 2009, a year after the App Store was launched by Apple. In that time we’ve collaborated with a number of changemaker brands and grown our team into a talented bunch that will help you achieve your goals. Get to know the gang you’ll be working with.
