Dogtown Media Reviews & Testimonials

Web App Review from Michael Paskow
Dogtown media helped to develop a new cross-platform app and web portal for a sleep health study involving insomniacs for the National Sleep Foundation. The team was reliable and developed an excellent experience for end-users. It has been a great experience working with DTM. The team is reliable and communicative. They come up with creative solutions and are always available for any and all maintenance issues that arise. Although I am not well-versed in pricing for app development, I do feel that the pricing may have been a little too steep. That said, the work they have produced is excellent, and I'm very happy I got to work with the team at DTM.

Call Centers Review from John Shammas
We've really enjoyed the time spent with Dogtown and their support in our product initiatives. They have always been readily available to talk through design ideas, technical challenges, or feature improvements. Communication has always been solid, with a reliable stream of beta builds (delivered to our own devices to test out) and detailed patch notes. We look forward to working with Dogtown on more projects in the future!

Web Design Review from Undisclosed
I hired Fingent to create a web-based application for my website's visitors. They communicated their strategy effectively and adhered to our agreement.

Big Fish Reviews & Testimonials
Eric Wexler's Review Sourced from Google
Working with Big Fish App Development was a fantastic experience. Sara and her team were professional, helpful, responsive, and incredibly easy to work with throughout the entire project. Building an app or software can be a stressful undertaking but Sara really takes an organized approach and explains the process step by step. Her deep knowledge and expertise really showed, and she consistently met deadlines while being flexible enough to work at whatever pace was needed.Big Fish was thorough, and always one step ahead — often thinking of things I hadn’t even considered, which made a huge difference in the App. Her input during the development process was invaluable.I highly recommend Big Fish to anyone looking for a skilled and dependable app developer. If you are coming into this with little AppDev knowledge, just know that Big Fish is fair and trustworthy. I couldn’t have asked for a better team in bringing my app and ideas to life!
Swing Time's Review Sourced from Google
These are really great people to work with, and they're based right here in Tampa Bay. I highly recommend Big Fish for app development.
Kym Jenkins's Review Sourced from Google
I've had really great experiences with Big Fish. Their attention to detail is only surpassed by the solid execution of app development with each project. One of the best app development companies that I've worked with, and I look forward to our next project together.

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.
