Great company to work with. If you want great service and friendly team this is your place!
Jack Deverson's Review Sourced from Google
I'm sure they do cracking development work, but all I've received, on two occasions, is really poor customer service. Both times I've gone to them asking for a quote, I've been given the impression that it was an imposition - either insinuating that we wouldn't be able to afford their rates, or ignoring the enquiry altogether for a few weeks before palming us off after the quote deadline. ("We didn't think it would be the right kind of project for us anyway.") I've found their communications brusque, bordering on rude, and as a business in the region seeking to work with other local organisations, frankly I expected better given their reputation. The small details are important.

Matthew Timion's Review Sourced from Google
I had the privilege of working with Atwix during a Magento 1 -> Magento 2 (Adobe Commerce) migration. Our e-commerce product was already highly customized and a bit "out of the box" in terms of implementation.Atwix was professional, detail oriented, and regularly met with us to ensure all of our needs were met, the product was fully scoped, and helped ensure success. They went above and beyond in terms of developer resources and expertise.Their deep knowledge of the Adobe Commerce platform helped reduce costs and made the whole process wonderful.
Eric Gozenput's Review Sourced from Google
Atwix has some of the best Magento developers we have worked with. The whole team is a pleasure to work with and extremely professional. Highly recommended!
Anton Kril's Review Sourced from Google
Having known Slava and a bunch of people from his team for the better part of a decade, I can attest to their remarkable dedication, intelligence, and leadership in the ecommerce development realm. It's no surprise to see Atwix being recognized for their work. This photo from Meet Magento New York where they receive a reward on behalf of their customer is just one of the many testaments to the outstanding service and commitment they provide to their clients. Congratulations, Slava and team! Keep setting the standard in the industry.P.S. Slava always knows which camera to look at.

Dean Lyttle's Review Sourced from Google
On behalf of AES Global Ltd -Moving our app development locally was a key focus for us in 2020. After extensive research into local companies and speaking to them all Ali, Danielle and the whole team at Sugar Rush most definitely came out on top.Their company culture and attention to detail was what caught our eye first which was followed closely on their project management skills.We are currently working on our 4th project together and i am still amazed with their dedication to learn our product inside out so they truly understand how it should function with the app and provide new ideas and better flows than what we had before.We have dealt with a large number of different colleagues within Sugar Rush and every single one of them are a credit to the company and provide a brilliant customer experience.Here is to the last 2 year partnership with many more years to follow. Thank you Sugar Rush for your partnership and helping to modernise and optimise our app platform.

Frequently Asked Questions About App Development Companies
What services do app development companies typically offer?
App development companies usually handle strategy, UI/UX design, development, testing, launch, and ongoing maintenance. Some also provide product research and app store optimization.
How much does it cost to hire an app development company?
App development agencies typically charge between $30,000 and $500,000+, depending on the scope and complexity of the project.
Typical custom app costs by scope include:
- Simple app: $10,000 to $35,000
- Medium-complexity app: $35,000 to $150,000
- Complex app: $150,000 to $300,000+
How long does it take to develop a mobile app?
Most apps take around 3 to 7 months to develop, though the timeline depends on complexity, features, technology, and the development team. Changes in scope, integrations, and testing requirements can also extend the timeline.
- Simple apps: a few weeks to 3 months
- Medium-complexity apps: 3 to 7 months
- Complex apps: 7 to 12+ months
How do I choose the right app development company?
Look at relevant experience, past projects, technical expertise, communication, and post-launch support. The company should also understand your business goals and target users.
What should I look for in an app development company’s portfolio?
Check whether they have built apps similar to yours and review the usability, design quality, and functionality of their work. Pay attention to projects in your industry or with comparable technical requirements.
What track record should I look for in an app development company?
Ask for launch counts, instead of project counts. An app development company that has shipped dozens of live apps has already solved App Store review, retention, and post-launch iteration. Designli, for example, lists more than 200 product launches and traces its process back to Applits, an app studio its founders ran before the agency existed.
