AI + React Native

AI apps that hold up
once real users arrive.

We design and ship AI features in React Native and Expo: chat, image recognition, voice. You get a build that survives a weak mobile connection, a model bill you can predict per user, and a submission that gets through App Store and Google Play review.

The call is with the engineer who would build it. No salesperson in between.

Challenges

Your demo works. Shipping it is a different problem.

A feature that works in a browser is not yet a mobile product. On a phone you also need a connection that drops and recovers, a model cost you can predict per user, sensible offline behaviour, store approval, and the native modules the feature depends on.

01

Responses stream fine on Wi-Fi and die on mobile data.

02

The model API key ships inside the app bundle.

03

Nobody has measured what one active user costs you.

04

App Review turned the app down over its AI feature.

Pricing

Three packages. You know the ceiling before we start.

Introductory pricing while we build our first client references, at senior-team rates that will go up later. The full scope of every package is on this page, so you can read it before you talk to us.

  • Audit and risk map
  • Keys, security and authentication review
  • Native code, build and release review
  • Critical fixes
  • Handoff notes
Included* with a build contract
Fix list in 2 days · up to $1,800 on its own
Order an audit
03 / from scratch

AI MVP

For an idea that needs to become a working AI app in the stores.

  • Audit included (fix list in 2 days)
  • Product scope and user flows
  • AI feature and model selection
  • Backend, data model and cost control
  • Authentication, deployment and store submission
  • Handoff and roadmap for next steps
Up to $12,000 · 4 weeks
Choose AI MVP

* You get the prioritised fix list within two working days, and the rest of the week goes on the critical fixes. The audit is included with a Production-Ready or AI MVP contract. On its own it costs up to $1,800, and you are under no obligation to continue.

Process

A price in 48 hours, then something to install every week.

Twenty minutes on a call, a price within 48 hours, and a ranked fix list within two working days of repository access. After that you get a working build every week, which tells you more than any status report.

01

Free consultation (20 minutes)

We look at the prototype, you tell us what worries you most, and we agree what 'ready' means for your users.

02

Proposal with scope and price (within 48 hours)

The scope, the delivery plan, our assumptions and the price. In writing, before anything starts.

03

Prioritised fix list (2 working days)

An existing project starts with an audit. Two working days after you give us the repository, you get every issue we found, ranked by what it costs your users and what it costs to fix, with an estimate on each line.

04

Weekly sprints

A build you can install every week, a short note on what changed, and a current list of what is ready to release.

05

Handoff and support

Documentation, the context behind the decisions, and a plan for after launch. Ongoing support is an optional retainer, never a condition.

Portfolio

We only publish work you can go and check.

A client project appears here once the client has confirmed the results and agreed to publication.

case studies / coming soon

Our first client projects are in progress.

We post progress on LinkedIn. Results, technology choices and client feedback land here as soon as we have permission to share them.

our own products / released

Two apps we designed, built and released ourselves.

ariex.fit (an AI fitness coach that recognises gym equipment through the camera) and Mira (a mindful photo journal on the App Store). Both run on React Native and Expo, and both have real people using them. Download either one before you decide about us.

Team

You work with the people writing the code.

The same three people handle the engineering, the QA, the delivery and the emails. Your project never gets handed to a team you have not met.

founder / cto

Volod

Founder and CTO. Architecture, code and every technical call, from your first estimate to the release build. The person who quotes your project is the person who builds it.

co-founder / development & delivery

Daria

Development, QA and delivery. She took Mira from the first commit to the App Store, and every Dyvertex project has to clear that same bar before it ships.

growth lead

Illia

The first person you talk to at Dyvertex. He works out what you actually need and hands you straight to the engineer who would do the work.

FAQ

Frequently asked questions

Can you add AI features to our existing app?

Yes. Typical work includes streaming chat that stays reliable on weak connections, camera and image recognition, voice, search over your own data, and moving model calls to a server so the API key is not stored in the app. We begin with an audit, so the quote is based on the actual code.

Will Apple reject an app because it uses AI?

Not for using AI as such. Rejections come from what surrounds the feature: user-generated content without moderation or reporting, an age rating that does not reflect what a chatbot can say, permissions without a clear purpose, data sent to a model provider that is missing from the privacy labels, or a subscription screen that does not explain what the AI does. We address all of these before submission. No one can guarantee approval.

Do you build both mobile and web apps?

We focus on mobile. That means React Native and Expo, native modules in Swift and Kotlin where a vendor SDK has no wrapper, and release to the App Store and Google Play. We also build the web apps and backends these products need. Each service page lists the exact scope.

Do you write tests?

Yes, and testing is included in the project price. Unit and integration tests cover the logic that is costly to get wrong, end-to-end tests cover the revenue-critical flows, and both run on every pull request so CI catches regressions before customers do. On mobile we run Detox from EAS Workflows against a real build before each store submission. AI helps us generate edge cases that are rarely written by hand, such as an interrupted upload, a session expiring during checkout, a retry after a timeout or an emoji in a name field. A senior engineer decides which are realistic. We don't chase a coverage percentage.

Do you sign NDAs?

Yes, before you share any project details.

Do you use AI to write code?

Yes, openly. Claude Code, Codex and GitHub Copilot speed up boilerplate, migrations and testing, and help surface edge cases. Architecture, security and the definition of production-ready stay with our engineers. Every AI-assisted change is reviewed by a senior engineer before release.

What if my project was not built with Lovable, Bolt, Replit or Base44?

That's fine. We also build products from scratch and take on standard web, mobile, backend and AI projects. AI builders are a common starting point, but you don't need one to work with us.

What size of projects do you take on?

Small and medium-sized. A single product, built by a small senior team. We do not take on large, multi-team enterprise platforms.

A freelancer quoted us less. Why work with you?

Sometimes you should hire the freelancer, and we'll tell you so on the call if that's the honest answer. The difference shows up in what happens around the code: someone else reviews every change before it ships, your repository and store accounts stay in your name from day one, and the handoff package is written into the contract rather than promised at the end. If the person who built your app disappears, you want to still be able to release.

Fixed price or hourly?

The three core packages have a price agreed in advance, so the risk of a bad estimate sits with us. Hourly billing applies to agency subcontracting, or when the scope genuinely cannot be pinned down yet.

What happens after launch?

You get the project back with full documentation. Ongoing support is an optional monthly retainer, and nothing we hand over depends on you buying it.

Free consultation · 20 minutes

Twenty minutes to find out whether we can help.

Send the repository, the build error or the rejection notice. We'll tell you what to do next: targeted fixes, a rebuild, or nothing at all. No pitch, and no pressure to decide on the call.

Prefer email? [email protected]
