WooCommerce Review from Amanda Viviano
We hired Qolos to build our local florist shop's website on WordPress and WooCommerce, and we couldn't be happier with the results. From the start, they took the time to understand our business and created a site that's not only beautiful but easy for our customers to browse and shop.
The WooCommerce setup was seamless, our online ordering works exactly the way we needed it to. But what really sets Qolos apart is their ongoing monthly maintenance. We never have to worry about updates, security, or technical issues because they stay on top of everything. Any time we've had a question or a small change request, they've been responsive and professional.
As a small local business, it means a lot to work with a team that genuinely cares about keeping our site running smoothly. Qolos has been a true partner, not just a vendor. Highly recommend them to any local business looking for reliable web design and maintenance!

Web Development Review from Sanjay Singh
I kept getting negative reviews about my app for technical glitches, heating issues, functionality, loading time, crashing, and more bugs. So, I reached out to QOLOS after going through 2-3 renowned review platforms. I explained my app issue to the team, and they did tremendous work with their mobile testing solutions. Also, I wanted to build a website for my app. They created a feature-rich and seamless website.

Shopify Review from Sarah Nesheim
Working with QOLOS was the best decision I have made in regards to scaling my business. They are professional, so creative, they communicate every step of the way and their pricing is fair for the highest quality work. The designer of our logo and website did it well and I am so impressed and proud of the final product! the designer listened and knew exactly what I wanted which made the process so simple. Seriously could not recommend QOLOS more!

Software Development Review from Anonymous
We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.

Software Development Review from Anonymous
For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.

Software Development Review from Lori Feld Oakley
Our Services organization is scaling quickly and we urgently needed a custom software application to automate our workflows, without breaking our annual budget. CodeStringers was the perfect fit, supporting us from ideation through go-live and everything in between. They innovated, hit their deadlines and released an amazingly high quality application that decreases our internal costs and improves our reputation with our customers. It would not have happened without CodeStringers.

CodeStringers is the perfect outsourcer to call If you have a solid software business idea but don’t know exactly how to bring it to life. They have both a top-notch development team as well as an executive staff with expertise in marketing, finance, and general business acumen. So they can not only build a product for you but they can make sure that the product you want to build is likely to succeed in the marketplace.

Software Development Review from Michael Levy
Flowty is a blockchain-based platform providing various transaction services around NFTs. K-Optional wears many hats in support of Flowty including Front End, Back End, business strategy, SEO and more.
The K-Optional team has been incredible to work with. They are proactive, supportive, smart, thoughtful and, most importantly, fit seamlessly into our team and company culture. To put it succinctly, we tried to hire them full-time...and then tried to buy their company to acqui-hire them.
Some of their strengths include: reliability, responsiveness and creativity. There are many groups out there that can perform some version of the work we are looking for. There are not many groups that are responsive at all hours of the day, deliver consistently and able to present data-backed business strategies.

Software Development Review from Jane Smarovozova
We collaborated with K-Optional to develop a custom inventory management dashboard tailored for real estate clients. We provided the creative vision and detailed designs, while their team focused on the software development, ensuring that every element was implemented perfectly. We worked hand-in-hand flawlessly, resulting in a sleek, user-friendly interface that not only looks great but functions seamlessly. The synergy between design and development allowed us to deliver a product that exceeded client expectations, combining aesthetics with powerful functionality.

Kawanda Real estate investor's Review Sourced from Google
Scam! If you’re going to offer potential new hires a job, the fair and responsible thing to do is tell people that they have to spend $350 upfront for the software inorder for them to even do the job. Not waste folks time with telling them once you connect to meet with the hiring manager that pertinent information. AGAIN, this should’ve been conveyed before offering the Offer Letter. Very deceptive and a waste! DO BETTER!

At its core, Concepta believes in providing their partners full visibility into the project lifecycle - know exactly where your project is, what is left to do and how the overall project is tracking.

Arrange for an interview and ask about the development process and project approach.
Select a Flutter development company with proven experience in your industry and project, align with your team's values, and offer post-launch support.
Need help finding a US Flutter development company? Visit our Marketplace and tell us about your project. We’ll match you with top companies for free.
What red flags should I avoid when selecting a United States Flutter development company?
When selecting a United States Flutter development company, avoid the following red flags:
Limited or no Flutter projects in its case studies and portfolio
Lack of knowledge in Dart code, state management, RESTful APIs, JSON, and other Flutter frameworks and widgets
Skips the user research and quality assurance (QA) processes
Weak security and compliance practices
Unrealistic timelines
Doesn’t provide post-launch support and maintenance
Ambiguous project ownership
Multiple client reviews that highlight problematic traits, like poor communication and project delays
What factors affect the pricing of a United States Flutter development company’s services?
Key factors that affect the pricing of a US Flutter development company’s services include:
App complexity: The core features and functions, number of screens and devices, user roadmaps, and overall deployment architecture
UI/UX design: Elements like custom animations, illustrations, interactive elements, and the number of page templates
Tech stack: Costs associated with software licensing, testing platforms, third-party integrations, custom library, server space, and infrastructure
Development team: The level of expertise required, and the number of team members (e.g., developers, designers, DevOps, QA specialists) needed to handle the project
Project timeline: Shorter project turnarounds usually require larger teams or overtime work, increasing costs
Regulatory requirements: Industries like healthcare and finance require more stringent security features and extensive QA testing, which can lead to higher costs due to increased workload
On average, you can expect to pay $15,000-$40,000 for a simple Flutter app and $80,000-$150,000 for more complex solutions.
How long does a typical United States Flutter development project take?
Typically, a simple Flutter app with basic design components and limited integrations can take between 10 and 17 weeks. In contrast, a complex app that requires real-time data handling and elaborate UI/UX design can take around 30-47 weeks.
Here’s a timeline breakdown:
Research and strategy: 2-5 weeks
UI/UX design and prototyping: 2-8 weeks
Development: 4-20 weeks
QA testing: 2-8 weeks
Deployment and post-launch support: 1-6 weeks
Do Flutter development companies in the United States provide ongoing support?
Yes. Leading US Flutter development companies provide ongoing support and maintenance in addition to their initial service warranty. Typically, this comes in the form of an extended service level agreement (SLA) or a flexible engagement model, which allows long-term, more in-depth app maintenance after the initial launch.
Ongoing support services include performance monitoring, security patch installations, platform updates, feature enhancements, and third-party integration management.
