Mobile App Development Review from Makaila Malungahu
Working with Chris and Mystic Media was the best decision. They designed and built our peer-to-peer wedding and event rentals app from scratch, and it looks and works great! We're super happy with our project!
Makaila Malungahu's Review Sourced from Google
Working with Chris and Mystic Media has been great for our huge app development project and excited to continue working with them. Don't hesitate to reach out to them!
Bryan Pratt's Review Sourced from Google
Mystic Media has been excellent to work with, offered great value, and their expertise and project management has been evident throughout the development process. We hired Mystic to take an idea and concept drawings through UI/UX and graphic design, programming and development, all the way to the market. They have met or exceeded all milestones, even with significant additions to scope along the way. We're currently in beta testing before release, and we are very satisfied with the entire experience. Mystic has earned my unqualified endorsement for anyone looking to develop their first app with them, as we have done.

The Development Factory Reviews & Testimonials
Tony Greco's Review Sourced from Google
TDF provided us with product management, development, and strategic consultation. We started to build the product with an individual and had initial wireframes and mock-ups, but the project quickly grew larger than an individual person could handle. TDF evaluated what we had and gave us feedback, then created a plan to replace and fix what had already been done. They started with extensive customer development-- something we missed the first time around-- so their new wireframes and plans were based on what our customers actually wanted. Then, they executed the plan.In addition to the development work, they also took care of logo and design work. They used Amazon Web Services for our platform. We have multiple features such as an API, database, and an administration tool for our own interface. We have a provider tool for facilities to update their data within the database. People can find resources on our web page, web application, and an iOS and Android app. We continue to work with them and have found it more effective and efficient to use them as a virtual outsourced department.
Tom Goddard's Review Sourced from Google
We are a consulting firm that specializes in working with healthcare organizations who are seeking to become accredited, stay accredited, or are working with particular healthcare legal compliance issues that we specialize in. The management of a typical accreditation process is complex for both the applicants and consultants providing them with help, so we wanted technology to help simplify and clarify that process.The Development Factory developed and designed two important pieces of software for us that have gone through multiple iterations over the years. The most important is an online project management platform that has all of our resources in one place and allows us to have secure communications with our clients and exchange documents and feedback important to the accreditation process. The platform also provides dashboards for our clients that allow clients to track their process and see how they're doing based on our scoring system that scores any documentation that will be sent to accreditation organizations.The second piece of software TDF built is a training program called AccrediTrain. We had a training software before, but they built a new self-service version that is completely automated, allowing a client to schedule a training for their employees without having to involve any of my staff.As a result of the work TDF did for our firm, we are now able to handle a larger number of clients with the same number of staff, helping us to increase our revenues by a factor of four.Beyond that, the reactions to our platforms have been outstanding. Just recently a new client was having her first experience with Goldfinch and she said it was just amazing. Another client of ours is a competitor and asked us for help on a project. This is an organization that has a particularly sophisticated knowledge about the accreditation process, and their CEO and president was very impressed by our software platforms.They really listened to our description of what we do and how we do it and then turned that into software that quite beautifully captures what we do and how we do it. They clearly care about us and our satisfaction.

I worked here and I found that Sileria is the best place to learn new things rapidly.
Fahad Shaikh's Review Sourced from Google
I worked at Sileria for an year when it was just an start up and that was one of the best learning experience I ever had. The company has top notch programmers and analyst that can solve any complex business problem. From building enterprise applications, to building 3D games, from building top quality search engine optimized websites to building Internet of Things applications, from top rated mobile apps to robotics, they do it all and they do it with top quality. They have excellent work ethics and a no-compromise policy on quality of the deliverables.
Kurt Wendt's Review Sourced from Google
I've worked with Sileria as far back as 1994 - in the very early days of Virtual Reality systems development. They were extremely adept at integrating data glove, trackers and head mounted displays with the VR systems development package. They worked with me on a number of VR projects over the years, along with doing database systems work.KurtOwner @ VR-FX, LLC

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.
