Testimonials

"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."

"Stormotion stood out because of their focus on Bluetooth-connected products. They weren't just app developers, they understood the unique challenges of building mobile app experience for hardware products. Their collaborative approach, technical expertise, and ability to quickly grasp the vision of the North Guardian app made it clear that they were the right fit."

"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!"

"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."

"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."

"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."

"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."

"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."

"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."

"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."

Our Software Development Codex

1

Solutions matter more than code.

Your value isn't in lines of code but in problems solved. Don't just execute requirements. Understand business challenges, question assumptions, and deliver outcomes that actually matter.

2

Testing in real conditions isn't optional.

Code that works on a laptop can still crash when users need it. Protocol connection drops differently on terminals and on phones. Our Android app development company tests on real hardware, devices, and environments.

3

Slow is smooth. Smooth is fast.

Prioritize clean code, solid architecture and thoughtful decisions. True speed comes only after deep understanding of the problem the software should solve.

4

Expertise means knowing why things break.

Saying "BLE architecture" doesn't mean understanding how to debug a dropped connection at 30 meters. Real knowledge looks like: reading GATT specifications, reverse-engineering protocols when manufacturers don't document them, and knowing why reconnection logic fails in specific scenarios.

5

Keep one eye on today, one on tomorrow.

You should know about Kotlin, Jetpack, and React Native updates because old approaches create maintenance problems. But don’t chase every new trend that isn't production-ready. Apps need to work today and stay maintainable in the future.

Android App Development Agency: Our Collaboration Models

Pre-Project

  • Discovery Stage

  • Planing

Agile Development

  • UX-Prototyping

  • Design

  • Development

  • QA & Testing

Transition

  • Maintenance

  • Handover

  • Next Iteration

Our development unit manages your Android product from planning to Google Play deployment. The team includes developers, designer, QA, and a PM. But exact team composition depends on the project and your requirements.

This model covers the full cycle: discovery, architecture decisions, design, development, testing on actual devices, and release.

Common scenarios:

  • Kiosk software for payment terminals, charging stations, or fitness consoles.
  • Branded applications to replace manufacturer white-label/OEM apps.
  • Companion apps for hardware: fitness equipment, medical devices, e-scooters, battery monitors.
  • MVPs with architecture that won't require rebuild later.
  • Legacy Android app modernization through gradual refactoring instead of full rewrites.

Our Excellence Pillars

Contact us
  • Expertise in protocol integration

    We implement custom protocols, handle GATT specifications, reverse-engineer undocumented firmware communication, and debug connection problems that only appear on actual devices.

  • CI/CD & automated deployment

    We use automated pipelines with EAS, Fastlane, and GitHub Actions. Every code change runs through automated tests, code quality checks, and device compatibility verification before app release.

  • 3.7-year average engineer tenure

    The same Android developers who started your project still work with you years later. They know your architecture, why certain technical decisions were made, and how everything connects. No constant handoffs to new contractors.

Android Mobile App Development Company – FAQ

How to choose an Android app development company?

You should choose a company with expertise in your industry and product. Building hardware products? Check for protocol integration and real-device testing. Need kiosk application? Look for Android app development companies with experience in custom launchers and OTA firmware updates.

Ask them what happens when requirements change mid-project or the team finds bugs in the app. The answer reveals how they actually work.

Is it worth hiring a mobile app development agency?

Worth it when you need expertise your team don’t have – kiosk app development, protocol integration or moving beyond OEM/white-label apps. Also, it makes sense when your backlog grows faster than internal capacity or you're launching a product without building a internal mobile team. The value of Android app development agency is experience with similar problems and technologies.

How long does it take to build an MVP for an Android app?

It can take 4-5 months to build an MVP for an Android app. Companion apps for single device go faster than kiosk apps with payment systems. Hardware adds time: protocol validation and integration and device testing. We build features that test your hypothesis first. Nice-to-haves wait after release.

How do you test Android apps that connect to custom hardware?

Clients ship us their devices: fitness machines, terminals, battery monitors, scooters, and so on. Then, we test Android apps on the actual hardware.

Protocols act differently on real devices and simulators. We test reconnection, data synchronization, low battery scenarios. Automated tests catch some issues, manual device testing catches the rest. Simulators maybe get 60% of hardware bugs.

How much does it cost to outsource mobile app development?

Freelancers charge $80-$150/hour but you need to coordinate everything yourself. So, add your time and resources to this number.

When you hire Android mobile app development company, you get a long-term technical partnership with co-creation and ownership mindset. For each project, we form a development unit with full-time developers plus part-time QA, designer, and PM. Monthly cost of the unit is about $10,000-$15,000.

How much does it cost to hire an app developer?

The average wage of the internal senior Android developers varies from $150,000 to $220,000 per year in the US or Europe. You get one person. When they're out sick or on vacation, work stops. If they quit, you start over.

Our development unit costs $10,000-$15,000 per month. That gets you developers, QA, a designer, and a PM who offer custom Android app development services. Someone's sick? Another engineer covers. Need backend help? Already included.

How much does it cost to develop an app for Android?

It’s hard to tell the exact cost, because the cost depends on the type and complexity of the Android app. But we can tell you the rough cost.
We form a development unit with full-time developers plus part-time QA, designer, and PM. The monthly cost of the unit is $10,000-$15,000.

An MVP app might take 4 months to develop. So, its cost is from $40,000 to $60,000. A companion app for one BLE device might take 5 months and it can cost from $50,000 to $75,000. Kiosk software with payment integration and custom protocols can run about 8 months. So, it can cost $80,000-$120,000.
