Mobile App Development
Mobile app development company in the USA. Native iOS, Android and React Native apps shipped to the stores in 10–16 weeks, with ASO and crash monitoring included.
HandsOnTech designs and builds iOS, Android and cross-platform mobile apps for U.S. businesses in 10–16 weeks — including App Store and Google Play submission, ASO, crash monitoring and the post-launch releases most agencies quietly stop returning calls about.
Apps that stay on the home screen
Half of all apps are deleted within a month of download. The ones that survive do one job clearly, open fast, and never make the user think about the technology. That’s the bar we build to.
When BusyHen came to us, parents were abandoning a seven-screen booking flow. We rebuilt it around how they actually book — on a phone, between school pickup and dinner — and cut it to three taps. Booking completion went up 2.4× and the app now holds a 4.8★ App Store rating. The lesson generalizes: the app that wins is the one that respects the thirty seconds a user gives you. Read the BusyHen case study.
What’s included in every app build
- Product strategy and UX — user flows, wireframes and a clickable prototype tested with real users before code
- Native or cross-platform engineering — Swift, Kotlin, React Native or Flutter, recommended per project
- Backend and API — authentication, data sync, push infrastructure and admin tools
- The unglamorous essentials — offline behavior, deep links, payments, accessibility and analytics events
- Store launch — App Store and Play listings, screenshots, privacy labels, ASO and review-cycle management
- Post-launch operations — crash monitoring, release trains and a 30-day bug warranty
Working builds, not status decks
Two-week sprints, and every sprint ends with a build on your phone. Week four you’re tapping through real screens. Week eight you’re giving feedback based on use, not imagination. By submission, the app has been in your hands for months — which is why our store review pass rate is high and our launch weeks are boring, in the best way.
Standups and demos run in your U.S. time zone, in one shared Slack channel, and the engineers building your app are in the call. No account-manager relay.
Native, React Native or Flutter — the honest trade-off
Cross-platform gets you both stores from one codebase — typically 30–40% cheaper and faster to iterate. It’s the right call for most business apps: bookings, marketplaces, dashboards, communities. Native is the right call when the app is the technology: real-time camera processing, heavy animation, Bluetooth hardware, widgets and watch apps.
Agencies that staff one stack will tell you their stack is always the answer. We staff both, so the project gets the recommendation it deserves — in writing, with the reasoning attached.
After launch: the part most agencies skip
Version 1.0 is a hypothesis — real users falsify parts of it within weeks. We stay for that part: reading crash reports and analytics, shipping fixes on a release train, adapting to iOS and Android platform updates, and prioritizing the feature requests that actually correlate with retention.
If you’re also growing the app’s audience, the same team runs ASO, SEO and paid acquisition against the same KPI dashboard. And if your app needs AI features — on-device or API-powered — see our AI mobile app development practice.

Why apps get deleted
Day-one delight means nothing if booking, checkout or onboarding fails on a bad connection.

Abandoned after launch
Crash spikes with no one watching. Reviews tank.

Common questions
How much does mobile app development cost?
Most HandsOnTech mobile apps land between $40k and $120k depending on platform count, backend complexity and integrations. An MVP scoped to one core job can come in lower. You get a written fixed-price quote with milestones after a free scoping call — before any commitment.
How long does it take to build a mobile app?
A typical app takes 10–16 weeks from kickoff to store submission. We ship a working build to your phone via TestFlight or the Play internal track every two weeks, so you're testing real software from week four — not reviewing screenshots until month three.
Native or cross-platform — which should I choose?
Choose React Native or Flutter when one team must ship to both stores fast and the app is mostly screens, lists and forms — it can cut cost by 30–40%. Choose native Swift/Kotlin for heavy animation, background processing, Bluetooth or camera pipelines. We staff both stacks and put the recommendation in writing with the trade-off math.
Do you handle App Store and Google Play submission?
Yes — listings, screenshots, privacy labels, review notes and ASO keyword optimization for both stores. If Apple or Google rejects the build, we run the resubmission cycle until it's live.
What happens after my app launches?
Launch is the midpoint, not the end. Crash monitoring, analytics dashboards and a 30-day warranty are included, then ongoing release management as real users surface feedback. OS updates, new devices and store policy changes are handled so your app doesn't rot on the shelf.
Can you rescue or take over an existing app?
Yes. We start with a code and crash-log audit, stabilize the worst offenders, then plan the roadmap — rebuilding only what's actually broken. About a third of our app work starts as a rescue from a previous vendor.
Built for founders who are done waiting on agencies.
One team. One contract. Working software every two weeks.
