Cross-platform app
development
One cross-platform app for iOS and Android with AI features built right into the interface. One product, two identical versions with no difference in features between platforms.
When to choose cross-platform development
Cross-platform development is a good fit if you care about:
Speed
You need to launch on iOS and Android at the same time.
One team for both platforms
The same team builds and ships both versions, so you fund one team instead of two.
One UX
The same experience for customers with no difference in the interface.
Simplicity
The app needs standard features and no complex integrations.
Beetrail does cross-platform app development for iOS and Android, with AI features inside the product. One product for both platforms is built by a single team using AI tools at every stage — from prototyping and coding to integrations and testing. The in-app AI logic is designed together with the base functionality rather than added later. MomSmile, an app for expecting and new mothers with an AI consultant inside, launched on the App Store and Google Play; the Bivvy messenger runs private and group chats, calls and media sharing on both platforms. A fit for companies that want AI features in their own app on both platforms at once.
Who cross-platform development is for
-
A new product

You have an iOS version and need Android too (or vice versa).
-
An AI-first product
AI features are the core of the app on both platforms.
-
You already have a web product
You have a web platform and customers ask for a mobile version.
-
Frequent updates
You plan to ship features regularly to both platforms at once.
How we work
01 
Free call
A 15–30 minute call where we look at how your work is set up and where time gets lost. We say where AI actually pays off and where it is overkill, and suggest a simpler route if there is one.
02 
Pilot or planning
For an AI task, we run a 4–6 week pilot on one of your processes and real data. For a large build, we start with a planning phase: requirements, architecture and the scope of work.
03 
Fixed-price project
After the first step, we name the exact project price, and it stays fixed. We build AI into your systems and check it on your data before launch.
04 
Monthly support
We look after the system after launch: monitor the quality of its output, retrain it on new data and add features as your needs grow.

The goal was not just another AI chat, but a voice assistant people could understand, with a character that felt alive. The team proposed a solution that met the goals of the first release and still left room to grow the product and add new AI capabilities.
Why choose us for cross-platform app development
One codebase
We write one app that builds to both iOS and Android. An edit is made once and lands on both platforms.
AI-driven development
AI tools speed up coding, testing and integrations at every stage — from prototype to release. Faster iterations without losing control.
Predictable timeline and budget
We agree on the timeline and budget before development starts. You know upfront what you’ll get and when, with no surprise rework or cost creep.
We stay with the product after release
We don’t walk away once it’s live on the App Store and Google Play: the same team fixes bugs, ships new versions and keeps it moving.
Frequently asked questions
Is cross-platform worse than native development?
For most business apps, no. A modern cross-platform stack delivers native-level performance and UX, while a single codebase for both platforms saves time and budget. We recommend native only where it’s genuinely needed.
Will the features be identical on iOS and Android?
Yes. We build one product with the same features on both platforms — no “stripped-down” version on either platform.
Can AI features be built in?
Yes. We design the AI logic as part of the app architecture from the start, so it works the same on both platforms.
How long does cross-platform app development take?
It depends on the scope of features and integrations. We break the problem down for free on a call, then give you a clear estimate of timeline and cost.
Let’s discuss your app
