Roots N Blues

First launched in 2007, the festival features over 30 artists representing the genres of roots, blues, gospel, country, folk, bluegrass, rock and soul.

Part of the challenge of the Roots N Blues app is creating a mobile experience that captures the spirit of the festival with fun and innovative designs that change each year. On top of that over 100 thousand people attend the festival each year, which causes saturated cell reception, so it is necessary for the app to operate fully in offline mode. Lastly, the organizers need to be able to make last minute changes to the schedule on the fly.


Every year, we work with the festival organizers to brainstorm the next version of their app. We then create designs and interactions that capture the theme of the festival for that year. To handle their data requirements, we have built back-end tools that allow the organizers to update app information and send push notifications from a web app. When we deploy the app, we...

Gametime

One of the fastest growing ticketing solutions for sports. We helped the company port their product from iOS to Android in 3 months in time for them to raise their series B.

We were asked to continue to build out new features on iOS while improving the underlying architecture of the app. On top of that, we were also asked to build the Android platform from the ground up.

We worked very closely with the Gametime product design and backend teams. When developing Android we built out a MVP with all the same features as iOS as soon as possible so we could test and tune the UI with the design team. At the same time, we worked on new features for the iOS version of the app.

While successfully adding new features to iOS, we brought the Android version of their app to market in under three months, giving them access to the other 60% of the mobile user base. Shortly after, Gametime successfully closed an $8 million A round.

Speedtest

Discover which internet service providers and mobile networks are fastest and measure your device’s cellular and Wi-Fi data connections.

When Ookla came to us, iOS 7 was still in beta, but they needed to have an update ready for when it came out. While iOS 7 added a lot of internal features for app developers, it broke many of the existing navigational and UI elements.

Because Speedtest supports so many users, backwards compatibility was a major factor in our approach to the problem. The original app was written in iOS 3 and they still needed support for older versions of iOS. We went through their existing codebase and resolved the issues caused by iOS 7 while successfully maintaining backwards compatibility for the older versions of iOS.

The update to the Speedtest app was published in time for the release of iOS 7, so Ookla didn’t miss a beat. On top of that, we were able to improve network testing accuracy in the app with some changes we made to the...

Eventbrite

Eventbrite is a suite of apps to help people going to events and the people who organize them.

Eventbrite’s apps have been around for over a decade and been through a lot of changes along the way. By sharing code and libraries amongst their different iOS apps, they were able to reduce the amount of duplicated effort on each project. They wanted to modernize their technical stack without compromising the quality of their existing product.

Quarkworks worked with Eventbrite’s internal development team to rewrite their iOS data/network architecture into Swift, reducing a lot of complexity along the way.

Eventbrite Organizer launched their app revision without technical issues. New developers are able to onboard rapidly and adding new features to the app is now much easier. With Quarkwork’s changes and other improvements made by the core team, they now ship on a monthly cadence!

Hello

Hello is an app designed to help connect people with shared passions.

Hello wanted to create a new social experience, focusing on a mobile-first approach. They had ideas and plans, but not the mobile technical expertise needed to bring a new product to market.

Quarkworks worked to write an iOS MVP for the hello app, then ported the app to Android in order to better reach international users. Then, the teams worked together to bring a number of new features such as a communities and potentials, as well as rewriting registration and navigation along the way.

Hello launched their app on both platforms and gained a following in Brazil and India. Because of the app’s growth, Hello was able to secure a round of investment from Google!

The Review
Feedback summary: 

QuarkWorks' top-notch Android development services helped speed up the delivery of the app without sacrificing quality. Their knowledgeable, proactive staff provided invaluable input and product advice, and also integrated extremely well with the company's established team.

BACKGROUND

Introduce your business and what you do there.

I managed the product development for notifications company. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with QuarkWorks?

We engaged QuarkWorks to build our mobile app for Android, involving a notification-driven platform that sends out highly-targeted, localized notifications. (It had already been built on iOS.)

SOLUTION

What was the scope of their involvement?

QuarkWorks built our mobile app for Android in collaboration with our developers to reach feature parity with our iOS version. In addition to notifications, the app includes live video-streaming capabilities. They also provided product advice throughout the engagement, bringing in some of their unique best practices for working within the Android ecosystem.

What is the team composition?

We worked with Bryan (CEO, QuarkWorks), Brett (CTO, QuarkWorks), and another developer. They were very helpful, integrating with our team seamlessly and providing valuable input along the way.

How did you come to work with QuarkWorks?

We learned about them through a mutual connection of ours and were impressed by their previous work. They'd worked on other high-profile apps that had similar technology needs to ours, so it seemed like a good fit.

How much have you invested with them?

We invested in the range of $10,000–$50,000.

What is the status of this engagement?

We started working with them last spring [2017] and finished the work within three to four months.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

QuarkWorks helped us launch a high-quality version of the app quickly. They paid a great deal of attention to our specifications, and addressed any minor bugs as soon as they came up.

How did QuarkWorks perform from a project management standpoint?

Their developers integrated well with our team, and were very detail-oriented throughout the engagement. We really appreciated the feedback and suggestions they provided. Most of the collaboration took place through daily standup meetings and over Slack and Trello.

What did you find most impressive about them?

They genuinely wanted to partner with us and believed in our company. It was one of the rare contracts we've had that actually felt like the vendor was a true partner.

Do you have any advice for potential customers?

From my experience, I'd definitely recommend working with them. They're great about integrating into an already established team and helping you drive the velocity of your products. Their staff has a wide skillset and can help you speed up the delivery of your products without sacrificing quality.

Feedback summary: 

QuarkWorks delivers high-quality code that’s both comprehensible and sustainable. Their engineers assist daily tasks and are vital to the development of new features. Assigned resources contact senior-level staff to overcome project challenges. Responsive managers provide a transparent experience.

BACKGROUND

Introduce your business and what you do there.

I’m the CTO of Hello.com. We’re a social networking startup specializing in mobile Android and iOS platforms. Our goal is to help people with common interests discover each other and start forming new friendships.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with QuarkWorks?

We needed skilled mobile app developers to assist our internal team during surge periods and feature releases.

SOLUTION

What was the scope of their involvement?

Engineers from QuarkWorks have been heavily involved in various aspects of our iOS and Android app developments. We utilize task management tools to come up with a list of weekly priorities. The QuarkWorks engineers grab items from those lists and interact with our core development team to work through coding problems, architecture changes, or bugs fixes. 

Since joining our daily efforts, they’ve helped complete a wide variety of tasks. This includes a full UX redesign, iOS to Swift conversions, and Java to Kotlin conversions. They’ve done backend architecture changes from Core Data to Realm and then to Room. They also assist event generation by making sure both platforms are sending the same information simultaneously.

What is the team composition?

We work directly with Bryan (CEO & Co-founder, QuarkWorks) and Brett (CTO & Co-founder, QuarkWorks). They oversee a lot of the high-end structure and appoint other engineers to fill the role of technology lead when they aren’t available. There are usually 2–5 developers assigned to our projects at any given time.

How did you come to work with QuarkWorks?

Our CEO met Bryan at an event. They developed a rapport and that started a long-term relationship between our two companies.

How much have you invested with them?

We've spent roughly over $1 million throughout the contract.

What is the status of this engagement?

We started working together in September 2014 and the engagement is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

The engineers at QuarkWorks are professional and always accomplish what they say they’re going to do in a given week. Occasionally, they’ll go above my expectations and email me over the weekend with new development ideas. Their code quality meets our standards in terms of architecture design, coding style, readability, and maintainability. They feel like members of our team instead of just a firm we hired for a few hours of work.

How did QuarkWorks perform from a project management standpoint?

It’s always a little tricky working across remote locations. We went through a couple of different tools to grant our management staff a detailed look at what QuarkWorks was working on without consistently looking over their shoulder in an overbearing way. Their project managers are readily available to answer our questions regarding development logistics.

What did you find most impressive about them?

When faced with a challenge, their developers will often reach out to resources that aren’t assigned to our project. As a result, we sort of have access to the entire QuarkWorks organization. For example, we’ve gotten code reviews delivered by senior architects because they noticed something and wanted to ask a question. It feels like we’re working with a startup-style group of people instead of one or two assigned resources.

Are there any areas they could improve?

Having a better understanding of their engineer and team schedules in advance would allow us to better plan sprints and releases projects around vacations, travel, or classwork. This matters because we engage with QuarkWorks more as though they are part of our development team, as opposed to contracting them to complete a project/task on their own.

Do you have any advice for potential customers?

If you take the time to get to know your project manager and senior engineers and really explain the project vision and goals to them, then they can bring their full expertise to the project. If you only hand them small piecemeal tasks, you'll really miss out on what QuarkWorks can provide.

Feedback summary: 

Both versions of the app have been well-received in the marketplace, resulting in several millions of dollars in sales. The app’s design is impressive, and the functions are user-friendly. The Quarkworks staff was communicative and hard-working.

BACKGROUND

Introduce your business and what you do there.

I am the CEO of a business that specializes in offering last-minute ticket-buying opportunities for sporting events, concerts, and theater productions.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Quarkworks?

We asked them to perform updates on our existing iOS app. After they completed that work, we wanted them to build our Android app. We wanted apps that appealed to a younger demographic.

SOLUTION

What was the scope of their involvement?

They were responsible for the full development of our Android app. We collaborated on the wireframes, and they were involved with our design, building the prototype, its implementation, and its release into the Google Play store. For the iOS updates, their most notable work was building the loading screen with custom animation, along with some UX/UI design.

What is the team composition?

We worked closely with their owner and a small team of developers.

How did you come to work with Quarkworks?

We met them at the Worldwide Developers Conference in San Francisco, and we were immediately impressed. We discussed potentially working on a project together, and eventually, we were able to.

How much have you invested with them?

We spent between $100,000–$200,000.

What is the status of this engagement?

We worked together from June 2013 through December 2015.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We’ve had millions of installations, and in 2016, we reported $50 million in sales. The apps are impressive in their functionality and visual design.

How did Quarkworks perform from a project management standpoint?

They worked very efficiently, and their turnaround time was impressive. We communicated mostly with email and Skype, and we met in person on occasion. They also worked out of our office at times.

What did you find most impressive about them?

Their attention to detail is notable.

Are there any areas they could improve?

No. I think they’re an outstanding service provider.

Any advice for potential customers?

We found it valuable for them to work in our office whenever possible so that we could better communicate.

Feedback summary: 

The completed application has excellent code and, as such, is easy for the in-house team to maintain. The team finished the project on time and within the required budget, while always communicating effectively and bringing a professional, initiative-taking attitude to the project.

BACKGROUND

Introduce your business and what you do there.

I’m one of the founders of a general-purpose software engineering firm. We make some of our own products in the mobile music space and we also do work for hire for other clients.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with QuarkWorks?

We had a client that we were doing some work for on iOS and we needed an Android version of what we had done. We didn’t have the bandwidth to do it ourselves.

SOLUTION

What was the scope of their involvement?

They built most of the Android app that we working on. We did a bit of the work in interfacing with some hardware that was involved, but they did all the UI and networking to make it communicate with the backend. We provided them with wireframes, an existing iOS app, and the iOS code. We told them we wanted to match the existing app as closely as possible. They were able to match a lot of the elements of the technical design too. The initial project is finished, but they’re providing work for us on another project with that same client.

The application is a smartphone interface to a personal breathalyzer hardware. It allows the owner to blow into it and record their breath alcohol test, then the smartphone interface to it allows you to control the breathalyzer with your phone. On a smartphone, we can provide more detailed instructions about how to use the device and walk people through the steps to get accurate readings. The device provides data storage and management including cloud backend.

What is the team composition?

Bryan (CEO & Co-Founder, QuarkWorks) does most of the project management and Jacob (Lead Android Developer, QuarkWorks) does some as well. The rest of the team is developers with different specialties. I’ve met 80% of the people we’ve worked with.

How did you come to work with QuarkWorks?

I was introduced to Bryan through a colleague.

What is the status of this engagement?

We started working together in June 2013 and the work is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Their work is great and it’s good to work with them. The code is very easy to maintain, clear, and readable. We’re engineers too and it’s really important to us that any subcontractors we work with are doing high quality work because we have to maintain the code.

How did QuarkWorks perform from a project management standpoint?

We have no complaints. All the projects have been completed on time and on budget, while the communication has always been very clear. I have a specific contacts who I let know if I need something, then it always gets done. We use Redmine, Subversion, and Git for source control.

What did you find most impressive about them?

Their professionalism and can-do attitude is the best.

Are there any areas they could improve?

Sometimes I’ll rely on outside software dependencies when my instinct would be to redo the work. Sometimes you can finish a project quickly by relying on a dependency, but maybe in the future that dependency might be abandoned by its maintainers and then you have a problem. They’re very good at working with me on this.

Do you have any advice for potential customers?

Do it. They’re a great group and they’re very easy to work with.
