Bilberrry Reviews & Testimonials
eCommerce Development Review from Kelly Johnson
Since partnering with Bilberry, we have seen a marked improvement in our websites stability and performance. Their team manages our backlogged issues with such efficiency that our monthly development spend has actually decreased. Estimates are consistently accurate, and we appreciate their proactive communication; if a projects scope evolves, they provide an updated estimate for approval before moving forward. Our monthly sprints are now seamless thanks to their reliable planning and ability to scale resources rapidly to meet even the tightest deadlines.
Web Development Review from Adam Ely, PMP
As Director of Operations at Sands Investment Group, I partnered with Bilberrry to lead the redesign and rebuild of our website, enhance our marketing operations, and streamline internal workflows. We chose Bilberrry for their strong technical capabilities, cultural alignment, and outstanding reputation. The project followed a well-structured four-phase process: discovery, design, development, and launch. From the beginning, Bilberrry took a strategic and collaborative approach, conducting workshops and technical audits to define a scalable architecture and intuitive user experience. Their team went on to create custom designs for more than 20 pages, build a flexible design system, and ensure the site met key standards for SEO and accessibility.On the development side, they customized a robust content management system tailored to our needs, incorporating dynamic listing features such as saved searches, email alerts, and early-access content for select users. The new site also connected seamlessly with our internal tools, enabling greater efficiency and automation across teams.The impact was immediate and significant: we saw a dramatic reduction in manual processes. Our team is now better equipped to manage content independently, while the platform itself is built for long-term scalability and performance.Throughout the process, Bilberrry was responsive, professional, and incredibly easy to work with. They communicated clearly, incorporated feedback quickly, and consistently brought thoughtful, strategic ideas to the table. Bilberrry's unique blend of strategic insight, technical depth, and design acumen made them an invaluable partner in creating a high-performing, visually polished digital platform tailored to our business.
Web Design Review from Ari Bixhorn
Bilberrry’s work gave our new website improved performance, greater SEO flexibility, and pages that are much easier to build. They delivered everything on time and kept communication proactive throughout. Their strong project management, technical expertise, and responsiveness built real trust during the process.

ELEKS Reviews & Testimonials
Software Development Review from John Armstrong
ELEKS was able to take our vision and help us deliver an app that empowers retail shareholders to make their voices heard. They’ve brought a depth and breadth of technical expertise and user experience design to challenge us on our assumptions on how people would want to interact with the app. From a mobile development perspective, we wanted to go to market with both an Android and an iPhone simultaneously.
Software Development Review from Mark Battcock
We are very happy with our ELEKS partnership; the dedication of the team is exceptional. We would certainly recommend ELEKS and would be happy to work with them again. In fact, they continue to be our partner for the 2nd phase of the CDX project to add even more customer services to the website.
Software Development Review from Huntly Christie
What impressed me about ELEKS is the culture. There is a very strong culture of discipline and performance, and software is a profession where discipline is very important. Good software development can only happen with a strong work ethic, and I think the ELEKS team really understands that.

Calibrate Reviews & Testimonials
Web Development Review from Malcolm Gibson
The business supplied an extraordinary front-end for our cybersecurity web application combining looks with capability. They showed a deep understanding of our market while crafting a user-friendly and straightforward user interface that lines up with our brand name along with security-focused requirements. The Calibrate team was very receptive to comments while recommending cutting-edge style options that improved the users experience. Their focus on detail, sticking to timelines, and dedication to quality made the whole project run smoothly and efficently. We are incredibly pleased with the end product which has actually gotten favorable comments from our customers plus end-users.
Mobile App Development Review from Sony Tiwari
The whole Team at Calibrate have been great from beginning to end, and we're excited to have a partner as we continue to grow. Three words I would use to describe Calibrate are organized, insightful and collaborative. From the outset the scope of work was clearly defined, but they also showed great flexibility working through changes that arose. Faizan is terrific at running our regular meetings and keeping everyone up to date on progress. The team has a good balance at listening to your ideas but also guiding with their experience and expertise.Our project took longer than anticipated because of issues unearthed during the development, but Kevin and the team worked through it all with us. They went above and beyond to make sure we were satisfied with the final outcome.This is a talented team for sure, but their passion and ability to collaborate effectively is what really sets Calibrate apart.
eCommerce Development Review from Lorien Yonker
I partnered with Calibrate to develop a new eCommerce website, expertly integrating it with Shopify. Its guidance on software operation and website maintenance for future collections was invaluable. I valued the agency's patience and helpfulness in teaching me software intricacies and quick adaptability to changing project scopes. What set Calibrate apart was its attentive approach. Calibrate's small team was ideal for addressing my concerns proactively. While some may find it a drawback, I preferred the agency's primarily virtual meeting approach. (Verified via email)

Hiring Guide: How to Choose a Leading App Development Company in the US
How do businesses evaluate and compare mobile app development companies?
To choose the best provider for their needs, businesses typically evaluate:
- Relevant experience: Proven delivery on similar app types, industries, or technical requirements, especially as many organizations outsource primarily to access specialized talent.
- Portfolio depth: Evidence of real, shipped apps with measurable outcomes rather than design concepts alone, as 55% of organizations report difficulty tracking realized value from external providers.
- Technical expertise: Ability to support required platforms, integrations, security, scalability, and AI-enabled capabilities, with 83% of executives expecting vendors to embed AI into service delivery.
- Process and communication: A clear development methodology, milestones, and reporting cadence, given that 53% of organizations cite organizational change management challenges and 47% report issues integrating vendor services.
- Pricing transparency: Well-defined hourly or project-based pricing with clear scope assumptions and change control mechanisms.
- Post-launch support: Ongoing maintenance, updates, monitoring, and optimization to prevent value loss after launch.
- Client feedback: Verified reviews and case studies that reflect delivery quality and reliability, particularly as 46% of organizations experience vendor performance issues during transitions.
How to differentiate a high-quality app from a functional one in an agency portfolio?
A stronger app stands out in an agency portfolio through evidence of product thinking, execution depth, and real-world performance, not just working features.
Watch out for:
- Clear problem framing tied to a specific business or user need.
- Polished user experience with intuitive navigation and refined interaction design.
- Technical depth such as custom logic, integrations, or scalable backend architecture.
- Performance signals including stability, responsiveness, and cross-device consistency.
- Adoption or outcome metrics like usage, retention, revenue impact, or operational gains.
- Evidence of iteration based on post-launch data or user feedback.
What risks should be contractually defined before signing with an agency?
Clear contractual safeguards help set expectations, protect both parties, and prevent common issues that can arise during complex development engagements:
The most important risks to address include:
- Scope definition and change control: Clearly defined deliverables, assumptions, and approval processes, as 38% of organizations report poor contract and change management.
- Timeline and delivery risk: Milestones, dependencies, and remedies if delivery expectations are not met.
- Cost overruns: Transparent pricing structures, payment schedules, and protections against unexpected charges, with 40% of organizations citing inadequate financial management as a contributor to outsourcing issues.
- Intellectual property ownership: Explicit ownership of code, designs, documentation, and related assets upon payment.
- Data security and confidentiality: Responsibilities for protecting sensitive data and handling breaches, especially as 29% of organizations report inadequate third-party risk management.
- Quality standards: Acceptance criteria, testing requirements, and remediation obligations, aligned with the fact that 33% of organizations prioritize improved quality and performance when outsourcing.
- Termination and exit terms: Conditions for ending the engagement and transferring work, assets, and knowledge, given that 46% of organizations report vendor performance challenges during transitions.
What questions should a business ask an app development agency before requesting proposals?
Before engaging vendors or requesting formal estimates, businesses benefit from clarifying capabilities, processes, and delivery expectations to ensure alignment and reduce risk:
Relevant Background
- What mobile app projects similar to ours have you delivered, and what outcomes were achieved?
- Which industries or app types do you have the strongest delivery experience in?
- What platforms and technologies do you most frequently work with (iOS, Android, cross-platform)?
Services and Processes
- Which stages of the mobile app lifecycle do you handle in-house?
- How do you approach discovery, requirements definition, and technical planning?
- What does your development, testing, and release process look like end to end?
Relevant to Your Project
- Who will be assigned to our project, and what roles will they cover?
- How do you manage scope changes, prioritization, and tradeoffs during development?
- What level of involvement and decision-making do you expect from our team?

FAQs About Mobile App Development Companies
What services does a mobile app development company in the US provide?
The core services of US mobile app development companies include product strategy and discovery, UI/UX design, development, quality assurance and testing, app store deployment, and maintenance and support. Some companies also offer system integration, internet of things (IoT) development, and AI product development.
Which platforms do US mobile app development companies typically support?
Most US development companies support Android and iOS systems and cross-platform frameworks. Many also build cloud-connected backend platforms and tablet-specific, multi-device, and ecosystem-level experiences.
StatCounter reports that that iOS accounts for 59.56% of the American mobile market share, while Android is at 40.46%. As such, it’s valuable to develop mobile apps according to your target users.
How much does it cost to hire a US-based mobile app development company?
Mobile app development costs in the US are about $100-$200+ per hour or $15,000-$30,000 for basic projects. Apps that require more complex features and functionalities can reach $150,000-$500,000+ per project.
What factors most influence mobile app development pricing?
Mobile app development pricing is primarily driven by a combination of scope, technical complexity, and delivery requirements. The most influential factors include:
- Platform choice, design requirements, feature set, and complexity
- Integration, security, and compliance requirements
- Timeline and delivery speed
How long does it typically take to develop a mobile app?
Mobile app development generally takes about 2-3 months for basic products and over 12 months for enterprise builds. Here’s a breakdown:
- Simple apps: 2-3 months, which typically have limited features and integrations.
- Mid-complexity apps: 3-6 months for custom UI/UX, backend, and third-party integrations.
- Enterprise apps: 6-12+ months for advanced functionality, scalability requirements, and extensive testing.
Does a US-based mobile app company build iOS and Android separately?
Most no longer do. Cross-platform frameworks allow one team to ship both platforms from a single codebase, which reduces cost and keeps feature parity. Designli, based in Greenville, South Carolina, uses React Native as its default mobile stack for exactly that reason.
