Mobile apps that feel native, without the cost of building twice.

We build cross-platform mobile apps for teams that need a real mobile experience without the expense or timeline of maintaining two separate codebases. When a project genuinely needs native, we’ll tell you.

Three ways to work with us.

Mobile engagements usually start as one of these, and often shift shape as trust builds.

01

Fixed-scope build.

You have a defined app with clear scope and timeline. We design, build, test, ship to the App Store and Google Play, and hand off against the deadline you bring us.

Best forNew apps or focused features with defined scope
02

Extended partnership.

We handle your mobile app on an ongoing basis: new features, OS updates, platform changes, iterative improvements. Mobile is not a ship-and-forget category.

Best forApps that will evolve beyond their initial version
03

Launch plus retainer.

We build the initial app, launch it, and stay on retainer to handle the ongoing work that mobile apps require: iOS and Android updates, new features, bug fixes, user feedback response.

Best forApps that need active maintenance post-launch

The mobile work we do.

A representative sample. Most of our mobile work falls into one of these shapes.

Internal mobile tools.

Apps built for field teams, operations teams, inventory management, sales reps in the field, or any internal function where a mobile interface does the job better than a desktop one. Usually the highest-ROI mobile work because they save significant operational time without the complexity of consumer app stores.

Mobile extensions of existing products.

You already have a web product. Your users want to access it on mobile. We build the mobile companion using the same backend and data you already have, with a UX designed around how people actually use phones rather than a shrunken version of the web app.

New consumer-facing apps.

Apps launching into the App Store and Google Play. New product ideas, category entries, or brand extensions that need a mobile-first presence. We handle the full build: design, development, submission, launch, post-launch iteration.

Cross-platform rebuilds.

You have an existing mobile app that was built poorly, abandoned by its previous developer, or isn't keeping up with platform changes. We rebuild it to be maintainable, performant, and ready to evolve.

How we build.

Three things that shape how we approach mobile work.

01

We default to cross-platform, and we’re honest about when to go native.

React Native and Expo handle the vast majority of B2B mobile work well. One codebase, two platforms, native performance for what most apps actually need. Native development (Swift, Kotlin) is the right call for projects with specific performance requirements, heavy camera or sensor work, or deep OS integration. We make the recommendation based on your actual needs, not based on what we prefer to build in.

02

We build apps that don’t fall behind.

Mobile platforms change constantly. iOS releases updates that break apps. Google Play changes policies. Libraries deprecate. Apps that shipped and were forgotten start breaking within a year. We build with maintenance in mind, choosing libraries that will still exist in two years, documenting the parts that need documentation, and leaving the app in a state where your team or ours can keep it current.

03

We handle the full path to launch.

Design, development, testing, App Store and Google Play submission, launch. Mobile submission is a real discipline, apps get rejected for surprisingly specific reasons, and the back-and-forth with Apple’s review team can add weeks to a launch if handled poorly. We’ve shipped enough apps to know what both stores want, and we handle that process rather than handing it off to your team.

In their own words.

“
We hired Alkali because we’d already been burned once and needed a partner we could trust. They shipped the app on the timeline they said they would, handled the App Store process we’d been dreading, and left us with something we can actually build on. Exactly what we needed.

Do you build native (Swift, Kotlin) or cross-platform (React Native, Flutter)?
Primarily cross-platform using React Native and Expo. Native development is the right call for apps with specific performance requirements, heavy AR or sensor work, or deep OS integrations. For most B2B mobile work, including internal tools, product extensions, and standard consumer apps, cross-platform produces a real native-feeling experience for significantly less cost and complexity. We make the recommendation based on your actual needs.
Can you build for iOS and Android, or just one?
Both. The benefit of cross-platform is that one build covers both platforms. In some cases, clients launch on one platform first (usually iOS) and add the second later, which works fine with our stack.
How long does a typical mobile app take?
It depends on scope and complexity. Simpler apps with limited features come in faster. More involved apps with complex backend integration, custom animations, or extensive offline handling run longer. We give you a specific timeline once we've scoped the project on our intro call.
Do you handle App Store and Google Play submission?
Yes. Submission is part of every project. We handle the metadata, screenshots, review responses, and launch coordination. If we've seen the rejection reason before, and at this point we've seen most of them, we know how to address it without eating weeks of calendar time.
What about backend work? Do you only do the front-end of mobile apps?
We handle backend too. Most of our mobile projects involve custom backend work or integration with existing systems. Mobile apps that only have a front-end are rare; most need APIs, databases, authentication, push notifications, analytics, and other infrastructure behind them. We can handle any of that.
We already have a web app. Can you extend it to mobile without rebuilding the whole thing?
Usually, yes. Most modern web backends can power a mobile app with minimal additional work. We evaluate what you have, identify what needs to change, and build the mobile app on top of your existing infrastructure rather than forcing a ground-up rebuild.
What happens after the app launches? Do we need ongoing help?
Mobile apps require ongoing work more than websites do. iOS and Android release updates that break apps, libraries deprecate, and users expect continuous improvements. Many clients stay on retainer with us for maintenance, new features, and platform update responses. Others take the handoff and come back to us when something big needs to change. Both work.
