“We would like to thank Roman's team for the enhancements they made to our app. We are very satisfied with the result and the team's work, and we would highly recommend them to anyone who needs an app. They corrected all bugs and adjustments without hesitation until we were satisfied, and now our very complex app runs flawlessly.”
“What stood out most was their ability to combine design thinking with practical implementation.”
“Roman built us a great bespoke CRM System that has pioneered our Sales function into offering a seamless client experience not offered by classic off-the-shelve CRMs.”
“Amazing to work with! The product is amazing and did everything possible get it perfect. Definitely will continue to work with on many more projects.”

FAQ
Before you message us.
Price, timeline, guarantees and what happens after launch.
How much does it cost to build a mobile app?
Our typical pricing for a launch-ready app is $25,000 to $50,000. After our free strategy call you get a custom fixed-price quote for your app.
How long does it take to build an app?
A clickable prototype takes 3 days. A launch-ready app takes 28 days, UI design included.
Can we work through Upwork?
Yes, if you prefer. We can run the contract on Upwork, where your payment is held in escrow until you approve each milestone. Every review on our Upwork profile is a verified 5.0. Either way, start by telling us about your app through the form and a founder replies within 4 hours.
What guarantees do you give?
A fixed price agreed before work starts, and an on-time launch with a bug-free product, or a partial refund. Conditions apply: the guarantee covers the scope and launch date we agree in writing, and changes you request mid-project move the date with them.
How much of my time will the project take?
Usually under one hour a week. You join a short demo at the end of each sprint, approve the next steps, and test builds on your own phone. We handle the rest.
How fast will you reply?
Within 4 hours. A founder reads every message and replies personally, then we schedule your free strategy call.
Who will I talk to?
The founders, directly. We do not have account managers.
Do I own the code?
Yes. You get access to the repository and the project board from the first day.
Can you take over an app another developer started?
Yes. We start with QA and a code review, then tell you honestly whether the app can be saved or needs a rebuild.
Do you offer design?
Yes. UI design is part of every full app we build, so design and development come from one team, and we also take on design-only projects.
Which industries do you work with?
Fitness, streaming, EdTech, MedTech, food and beverage, sports, nightlife, IoT and hardware, CRM and booking, crypto, family and community apps. Our clients are startup founders going all-in on their app and business owners who need an app to grow an existing business.
What happens after launch?
We stay on. We monitor, fix, release updates and scale the backend as you grow. DomaTV grew from an MVP to 35,000+ monthly users over a partnership that ran past two years.
