Testimonials from our clients
"I had meetings with 30 different agencies and the team at Stormotion gave me the most confidence to go forward. With them you feel like you've got a kind, knowledgable & conscientious team behind you. So I was 100% sure that they're going to be able to deliver our project!"
"If you're thinking of going to Stormotion, you're going to have a very easy team to talk to, to communicate with, to understand what you want to do. They will tell you if you're barking up the wrong tree and are going to waste your time and money. I'd say "give it a go!" and I thoroughly recommend Stormotion."
"Stormotion has really delivered on their promises. They’ve been very transparent about their progress, flexible in reacting to changes, and solution-focused in overcoming challenges. If they didn’t know something, they would find out, which gave us great confidence in their ability to go the extra mile."
"We originally got in touch with Stormotion from our original app developer. And very soon we found real value in choosing Stormotion, because they previously had real valuable experience on the field – digital apps working in the realm of EV charging. So, it was really a no-brainer for us to to go with them."
"I highly recommend Stormotion as a service provider for app development. They're young, flexible, dynamic, creative and very fast. The cost of planning and implementation is also reasonable. As they use "pay as you go", have a good plan first – then the result also will be satisfactory."
"The Stormotion team quickly became our team for everything Native app-related. It would be hard to name all the things that we built over the many years we worked together, but overall, I think we had a good partner who was able to adapt the way we worked, and the way they worked. So that we could ultimately build a product that had the quality that we wanted and with the speed that we wanted."
"Given a tough budget and a lack of knowledge in our own engineering team, we quickly came to Stormotion. We had already worked together on previous projects, and I knew that, based on React Native, we could have one engineer responsible for it. That was just amazing because I could really focus on our customer side, knowing that the mobile application for the testers was in very good hands."
"Trust Stormotion. Work with them on your road map, on your technical debt. Also, expect feedback because the team is eager to do this. It's what I value and, I think, many startups value."
"Working with Stormotion was a blast! The Project Managers, and especially Alex, are always there for you when you need them to go the extra mile. And it's very easy to communicate with them. Whether it's something urgent or whether it's a bigger task, like building the structure of the architecture, I always felt like I was treated very well. Stormotion delivered a great app experience from day one."

FAQ for Fitness Mobile App Development Company
What is the best fitness app development company?
The best fitness mobile app development company is one that combines deep knowledge of fitness, wellness, and connected devices with full-cycle development capabilities. Look for a company with proven experience in the fitness niche and BLE integration, companion apps, live and on-demand workout platforms, and scalable mobile solutions. Other important indicators include solid experience, satisfied customers, and case studies in your niche.
How much does it cost to develop a fitness app?
The cost of developing a fitness app depends on its type, features, and complexity. Simple apps can cost as little as $25,000, while multifunctional platforms with BLE integration, live streaming, or personalized AI-based recommendations can cost up to $75,000 or more. Working with a professional fitness app development company ensures that your budget is optimized for quality, scalability, and user retention.
Which Health APIs do you have experience with?
We have extensive experience integrating APIs such as Apple Health, Google Fit, Fitbit, Garmin, Strava, Withings, and others – from numerous fitness and wellbeing projects.
Can you show a live demo?
Sure – for example, STEPR or ForceUSA. Just reach out, and we’ll gladly show you a current project.
How do you ensure my idea and business model are protected?
We always sign an NDA before starting a project. Additionally, we follow secure data handling practices – e.g., GDPR- and HIPAA-compliant, depending on the use case.
What features can my fitness app include?
All features that best suit your use case – from workout tracking to subscription logic. We only develop customized fitness app development solutions.
Can you also develop a web version?
Yes. Many of our clients start with mobile – like FitTracks – and then expand to the web. We are happy to assist with porting.
Do you also develop a web dashboard?
Yes. For dashboards, we use tools like React Admin or GraphCMS, tailored to the specific use case.
Which devices can you integrate?
From fitness trackers and smartwatches to biosensors and kiosks – we have experience with various BLE devices. For STEPR, for example, we integrated heart rate sensors and monitoring tools.
Can I create my own fitness app?
Yes, you can create your own fitness app! Whether you want a companion app with BLE connectivity, a training platform, a nutrition tracker, or a complete digital ecosystem, working with a professional fitness app development company ensures that your app will be user-friendly, scalable, and profitable.
Do you provide ongoing support and maintenance?
Yes – we offer regular updates, bug fixes, SDK and API updates, and support for developing new fitness app development solutions.
Do you support existing (legacy) projects?
Yes – whether maintenance, redesign, or porting from iOS/Android to web (or vice versa), we can step into ongoing projects.
Can you build a duplicate of an existing fitness app?
Yes, we can develop a clone of an existing fitness app. However, it’s important to consider a few key aspects:
- Legal aspects: Direct copying can violate copyrights, so we recommend adding unique elements.
Functionality: We can implement popular features and offer innovative solutions. - Cost: The development cost of a clone depends on app complexity and number of features. For example, the cost for an app like Fitbit ranges from $98,300 to $143,850, while an app like Peloton costs between $92,050 and $145,000.
Contact us to discuss your ideas or get an exact cost estimate for such an app!
Do you provide integrated analytics?
Yes. We integrate analytics solutions for workout evaluation – e.g., session duration, activity frequency, or goal achievement.
How long does development take?
Typically 3–6 months – depending on app type, feature scope, and team setup. After an initial consultation, we can provide a realistic timeline.
Do you sign an NDA?
Yes, absolutely. The confidentiality of your idea is secured from day one.
Do you develop for iOS and Android?
Yes – with React Native, we develop cross-platform for both systems. This saves time and costs without compromising performance.
How do you secure user data?
We follow best practices: end-to-end encryption, secure authentication, GDPR-compliant processes. After launch, we regularly review security-critical components. We are recognized as a reliable firm in the fitness technology sector.
