iOS, Android, cross-platform Mobile app development

Mobile apps built
to launch and last.

iOS and Android apps in Swift, Kotlin, React Native or Flutter, from the first release through store review and every OS update after. For teams launching an app, or running one that crashes, rates poorly or is hard to change.

What we build

Six kinds of app work we take on most

Most projects start with one app on both stores. The same back end, design system and release process then carry the next version.

01

Customer apps for iOS and Android

Apps for your customers with sign-in, payments, push notifications and analytics, designed to Apple and Google guidelines.

For exampleA booking app with Apple Pay, Google Pay and reminders
02

Cross-platform apps in React Native or Flutter

One codebase for both stores when the app is mostly screens, forms and data. We tell you when native is worth the extra cost.

For exampleA React Native app sharing its API with a web dashboard
03

Native apps in Swift and Kotlin

For apps that rely on the camera, Bluetooth, background location or heavy graphics, where native performance matters.

For exampleA Bluetooth app that pairs with a connected device
04

Field and staff apps

Apps for inspections, deliveries and stock checks that work offline and sync when the signal returns.

For exampleAn offline inspection app with photos, signatures and PDF reports
05

Back ends, APIs and admin panels

The APIs, databases, push services and admin dashboards your app runs on, built alongside it.

For exampleA Node.js API and admin panel for content, users and orders
06

App takeovers, updates and support

Crash fixes, OS and SDK updates, store policy changes and new features for an app another team built.

For exampleTaking over an unmaintained app and clearing its crash backlog
Why Leapstrat

Why businesses choose Leapstrat for their app

A no-code app builder compared with an app built by Leapstrat. A builder can be the right start for a simple prototype; we help you see where it stops fitting.

01

A founder on every project

One of our two founders joins the workshop and stays on the project as your point of escalation.

02

Hours that overlap yours

Engineers on shift 09:00–23:00 IST: 4.5 hours with US Eastern, a full working day with the UK and Europe.

03

Handover planned from day one

Code, build pipelines and store access are kept ready for your own team to take over.

Worried about store review? We prepare the listing, privacy labels and test accounts, and handle any rejection with Apple or Google.

How a project runs

A typical app in both stores in 14 weeks

Designs are approved before build starts, and you test every sprint’s build on your own phone. The bar shows a typical project, week by week.

011–2 weeks

Discovery and prototype

We agree the users, features, platforms and integrations, then click through a prototype before anything is built.

You get: Feature list, prototype and fixed estimate
02About 3 weeks

Design

Screen designs for iOS and Android that follow each platform’s conventions, reviewed with your team on real phones.

You get: Approved designs for every screen
03About 7 weeks

Build and test

App, API and admin panel built in two-week sprints, with a test build on your phone after every sprint.

You get: Test builds through TestFlight and Google Play
04About 2 weeks

Store release

Device testing, store listings, privacy labels and submission, then a staged rollout with crash monitoring on.

You get: Live app in both stores and a launch report
05Ongoing

Support and updates

OS and SDK updates, crash fixes and new features each month, with crash rates and ratings reported back.

You get: A monthly crash and ratings report
Every sprint: A test build on your phone Crash reports from testers Screens ready for your review An updated estimate if scope changes

Crash-free sessions after the takeover

A delivery app takeover that drivers trust again

ChallengeA delivery app built by a previous agency crashed on older Android phones, and drivers went back to paper forms.
ApproachWe took over the React Native code, rebuilt offline sync, upgraded the SDKs and added crash monitoring and device tests.
Result99.8% of sessions run without a crash, and drivers complete deliveries offline and sync when back in signal.

Industries and technologies

Apps for seven sectors, on the stack that fits

The sector sets the rules for privacy, payments and accessibility. We choose native or cross-platform by what the app needs from the device.

Dedicated team or fixed-price project: how to choose for your next build

Most software engagements fail the brief before anyone writes code, because the commercial model does not match how the work will actually change. A dedicated team and a fixed-price project are both valid. They answer different questions. Choose a dedicated team when the roadmap will move A dedicated team is the right shape when you […]

Shipping an MVP in 12 weeks with a distributed team

Twelve weeks is enough to put a product in front of real users. It is not enough to build the version you will be embarrassed to throw away later if the first month is spent negotiating the backlog. Week 0 is a decision, not a workshop Before the first sprint, name the user, the job […]
