Key questions on mobile development services
What is mobile development?
It’s building an app people use on their phones. Beyond the code, mobile development includes UI/UX design, product design, backend development, and infrastructure.
How much does a mobile app cost to build?
Whether it’s MVP development or a full build, your key drivers are platform choice, feature complexity, and your engineers’ location.
A standard-features MVP can run in the low tens of thousands, but a mobile app with AI features or a custom backend costs several times more.
US-based senior developers bill $100–$250+/hour; vetted teams in Eastern Europe or LatAm typically run $40–$90/hour for comparable seniority — those prices you get with Lemon.io.
What’s included in mobile app development services?
As a custom software development partner, Lemon.io covers:
- Product strategy and wireframes — if you’re starting from scratch;
- UI/UX design;
- Native (iOS/Android) or cross-platform (Flutter, React Native) engineering;
- Backend development in Node.js or Python;
- Cloud setup on AWS or Google Cloud;
- QA and DevOps;
- Google Play and the App Store optimization with further public launch.
If you only need one piece — say, staff augmentation for an existing codebase — that’s on the table too.
Do you build for both iOS and Android?
Yes.
What tech stack do you use?
Swift and Kotlin for native iOS app development and Android; Flutter, React Native, or Ionic for cross-platform solutions. Node.js, Python, and JavaScript for backend development, with CSS and modern frontend frameworks for anything browser-based.
Where the product calls for it, we handle AI integration—artificial intelligence, generative AI, and machine learning — as well as Internet of Things (IoT), augmented reality (AR/VR), blockchain, and ERP systems.
And we build progressive web apps (PWAs) when a browser-based version is a better fit than a mobile app.
Why outsource mobile development instead of hiring in-house?
Mainly speed: an in-house hire takes 6–12 weeks to land; a vetted team from Lemon.io can start within days. You also save time on screening and managing engineers directly — our delivery manager handles that.

Insurance
Lemon.io helped us build the team quickly and get things running smoothly. We went from A to Z — and rolled out a fully functioning insurance product within the first six months.
Fintech
We told Lemon.io exactly what we needed, down to the time zone and the kind of personality that would fit our team, and they found that person. He onboarded, reviewed the codebase, and worked on closing tickets within two weeks of starting with us.
Education
By week 2, I was like, ‘Okay, wow, I’m seeing so much stuff.’ By week 4, I was like, ‘I would trust you with my child.’ Lemon.io built Pirch so well and documented everything so clearly I’ve been able to add features myself over the last 30 days.
AI
With Lemon.io, we had relevant senior candidates within a week — smoother and more cost-efficient than any other channel we'd tried. Their team delivered several vetted profiles within 24 hours.
Bring the idea. We’ll bring the mobile app.
One 30-minute call gets you a platform recommendation, a budget range, and a start date.
