"What I liked about working with Bayinteractive was how well (and quickly) the company "got" our complex technology, and translated it into a compelling story."

Josh Slobin
Daintree Networks

"Bayinteractive is an excellent resource and everyone is very impressed with the work. Always on time and responsive to email. Went out of your their to understand a very complicated subject and made suggestions for improvement."

Jayson Shmueli

"Thank you Bayinteractive for creating my app and making it available on the App Store. I came to Bayinteractive with no app experience, just the concept and the math behind it, and their folks did the rest. I was never treated like I didn't know anything about the app process (which I didn't). We'll be in touch."

Jim Bosler
Interest In Shopping

"The experience with Bayinteractive was good, straightforward, easy to deal with and timely. Thank you"

Colin Rogers

"I believe I've worked on three major projects with Bayinteractive over the past 5 years. In each instance, it was a very positive experience! In all cases, the speed of service, functionality, project management/customer service and flexibility were top notch."

Ellen Roder

"I have worked closely with Bayinteractive for over 1-1/2 years on two separate projects. I have found their designs to be modern and creative with good attention to usability and style. They consistently produce results on schedule and respond quickly to design iterations with enthusiasm. The staff is pleasant to work with and I would highly recommend them for our upcoming projects."

and how we do it

We translate business requirements and ideas into highly usable and engaging mobile apps. Far beyond design and coding skills, this requires business strategy combined with a thorough understanding of user, platform, and market trends. We do this on a daily basis, and have done so for years. We know our stuff and that's why we're good at it.


Your mobile device now controls the world around you. We make the software that connects phones and tablets to medical devices, smart office appliances, toys, sensor arrays, and everything else that can be Bluetooth enabled.

We build Native Apps for iPhone, iPad, and iPod. Executive dashboards with fancy interactive charting or consumer convenience apps targeting the new mobile on demand economy. We integrate stunningly beautiful interfaces with fun and instantly accessible touch interactions. We can help you publish your app in the iTunes App Store, or work directly with your IT team to support enterprise deployment.

We build Native Apps for Android devices. Apps that allow users to search for local restaurants, browse menus, and order food for pickup or delivery. Apps that dramatically increase productivity within small teams. Apps that invite other network devices to join a LAN. Apps that monitor your battery and alert you via Facebook and Email when the battery dies, so you never lose your phone again. We can build and help you publish your app on the Google Play and Amazon App Stores, too.

We can work with you to get your app onto the Microsoft App store (MarketPlace) and ultimately into the hands of Windows Phone 7 users worldwide. By combining our experience in Silverlight and rigidly adhering to best practices for dynamic interface layout, multithreading and multitasking system support, we can deliver engaging, user centric apps. In addition we can also integrate with legacy enterprise systems, leveraging existing IT infrastructure.

Building on our extensive experience in J2ME, we can develop Blackberry apps that are portable to other Java platforms (e.g. Android), while our experience with Adobe AIR allows to build rich media apps for the Blackberry tablet OS.

agile development

We use an agile development approach to provide a high degree of transparency into the development process. Once wire frames and creative have been approved and development begins, we provide frequent builds for download and review (typically weekly). This ensures key stakeholders have the opportunity to see the app come together, and allows for rapid iteration and feature revision as business needs change.


Back in 2002 we started as a three man team. Over the last ten years we've grown to twenty five. We don't have foosball tables, desk massages, wacky mascots, or a selection of fine restaurants on campus. We do have a simple professional culture that encourages, recognizes, and rewards exceptional thinking, design, and development.

The Challenge

Eat24 approached Bayinteractive to design and develop a mobile version of their web application. One of the main challenges was to design an interface that supported the extensive feature set present in the app, without sacrificing usability.

The Strategy

We researched the App Stores to review apps in the same space. Our creative team and information architect then worked closely together to define a user flow for the app that would allow us to put some sizzle into the experience, whilst streamlining the search and ordering process.

The Results

We delivered a stunning app that allows users to search local options from over 20,000 restaurants in more than 750 cities. Users can browse the menus of each restaurant, select options and order food, redeem coupons, and use a real time chat to get support for their order. Since launch the app has been extremely well received with thousands of downloads and is averaging a rating above 4.5 stars in the iTunes App Store.

Do I need to work with a professional app development company?

You have two options for contracting your app development project: You can hire a freelancer or a professional, established firm like Bayinteractive. We recommend the latter. Here's why:

It takes a lot more than coding

The Mobile Apps marketplace is crowded and getting more so every day. To stand a chance of a successful app launch, you will need much more than coding services. You will need to work with a team that can guide and advise you on technical, marketing, and business strategy. We've got the experience, skills, grey hairs, and confidence to help your idea succeed.

How much does it cost to build an App?

It depends. Simple apps can be built for less than $10k. We can provide you with a fixed bid proposal as soon as we can get a good idea of what your app will do. Typically 15 mins on the phone is all we need to gather enough information for a proposal. For more complex or larger apps, or if you would like help figuring out the key features, we can schedule a meeting and brainstorm whiteboard session at our office.

How long does it take to have an app developed?

When you have a great idea, it's important to get to market quickly before someone else does. For this reason, we typically help our clients refine a minimum feature set for version 1.0 so they can launch the app to start building momentum, and quickly follow up with updates that address the most requested user features. It's a cost effective and smart approach, because users will tell you what they want and how they use the app.

Would you be willing to sign a Mutual Non-Disclosure Agreement?

Sure of course. We spend a large part of every day discussing stealth business plans and app ideas. It's our first priority to establish a secure and trusted conversation so you feel entirely confident sharing your ideas and equally, we can openly discuss our internal processes, secret sauces, and industry advantages our own competition would dearly love to know.

Do you help get the app submitted to the Apple/Android Stores?

Yes we sure do. We can help craft the marketing content to support the app, and advise you on strategy to gain valuable marketing footprint in the App Stores.

Who owns the app once completed?

You do. Once we get final approval we provide all source code for the app including all rights to use, modify, or sell the source code as you see fit.

What is your process on working on a project?

Simply put - Discover, Develop, Deploy. Before writing a line of code we make sure we understand what the app needs to do. Then we spend some time figuring out the best way to meet those requirements, planning the user flow, and defining the architecture for the front and back ends. When we've got a good game plan, the creative team starts work on the interface design, and the dev team starts wiring up the app logic. We like to show our clients progress as it happens, so we typically provide a weekly build for review. This means you get to see your app come together from the ground up over a short space of time. It also means you are intiniscally involved in the testing and review process, which means we can adapt to changing business requirements on the fly.

What is your service guarantee?

Upon final approval (usually when the app is published to the App Stores), Bayinteractive provides a 60 day window during which time we will fix any defects or bugs discovered that are clearly in contravention to the app specifications. After this 60 day window, we will evaluate issues on an individual basis. If we determine that the issue is not a bug, or falls outside the original project scope, we will simply charge you on a time and materials hourly basis to resolve the problem.

I want to hire Bayinteractive, how do we get started?

Great! Call us so we can discuss your project and prepare a fixed bid proposal to define the scope of work, the price for that work, and the time line and milestones. As soon as we have that agreement in place, we can get started on your app using our standard Agile Process.

Once my app is developed what services do you provide for bug fixes, updates, etc?

The nature of software is organic. Your app will require updates to take advantage of new device features (e.g. iPhone 5's larger screen), and you will get user requests and feature wishlists. We're here to support your business goals with the app, so once the app is in the App Stores, rest assured you can hire us to make any updates to the app at anytime no matter how small. Typically, we find ourselves working on version 2.0 of the app within days of a successful v1.0 launch.

What content is allowed in an app?

Apps can be built around any subject or category. The app must not violate or infringe any patent, copyright, trademark, trade secret or any other intellectual property rights of any other entity. The app must not contain any obscene, offensive or other materials that are prohibited or restricted by laws or regulations of the countries in which the app will be distributed.

As the demand for digital media applications continues to grow, so have we. As such, we are continuously seeking A players to join our team.
