[New York City]
Build an iOS, Android or cross-platform product with a senior team that works the way New York companies buy: a scoped phase, a fixed price for it, and code you own at the end. We take on new builds, rescues of apps that stalled, and modernisations of software that still earns its keep but no longer ships.
A New York roadmap tends to be bounded by something other than engineering — a launch tied to a funding round, an integration a partner controls, a regulator's calendar. We scope against the binding constraint first and build around it, rather than discovering it in month three.
Teams are senior and small. The engineers who scoped your build are the ones who write it, which is why a question about a decision made six weeks ago gets an answer rather than an archaeology exercise.
Every phase ends with something installable. You see the product on a device at the end of each one, not a status report describing a product you cannot open.
At handover you get the repository, the pipeline, the infrastructure definitions and the runbooks. Keeping clients through lock-in is a worse business than keeping them through work they want to continue.
One team across the whole surface of a product — the apps people touch, the services behind them, and the pipeline that gets both into production without a weekend of ceremony.
Swift and SwiftUI, built against the current SDK rather than the one that was current when the project started. Biometric authentication, offline behaviour that survives the subway, and a submission we take through review ourselves.
Kotlin and Jetpack Compose, tested across the device and OS spread your analytics actually show instead of the three handsets in the office drawer.
React Native or Flutter where one codebase genuinely serves both stores, with native modules written only where the bridge would cost you latency a user can feel.
The services, data model and integrations the app depends on — built to be read by whoever maintains them next, which is frequently not us.
An existing build that has slowed, broken or outgrown its architecture. We audit first and tell you plainly whether the right answer is a rewrite or a repair.
Signing, staged rollout, crash monitoring and the store paperwork, set up so your own team can run a release without calling us.

Bring the problem rather than a specification. We will tell you what we would build first, what it costs, and the cases where the honest answer is that you do not need an app at all.
Six products we took from a scoped phase to a store listing. Three of them have a full case study; the rest are summarised here.
Verified rent and sale listings, location and price filters, and OTP sign-in that keeps onboarding quick.
View Case StudyA competitive multiplayer dice game for iOS and Android, with tournaments, leaderboards and friend challenges.
View Case StudyAn insurtech platform across web, iOS and Android that estimates cover before a homeowner asks for a quote.
View Case StudyA wellness product built for daily use, where the retention problem is the design problem.
A parenting app whose content has to be as trustworthy as it is easy to reach at 3am.
Fleet and dispatch, designed for a dropped signal and a locked screen before anything else.
The constraints change more than the stack does. A trading tool answers to an auditor, a clinical app to HIPAA, a marketplace to whichever payment processor it depends on — and the architecture follows from that rather than from a preference.
Five phases, each ending in something you can open. Nothing moves to the next until the last one has shipped.
Two to three weeks working out what the binding constraint actually is — a funding milestone, a partner's integration, a compliance review — and scoping against it rather than around it.
You leave with a phase you can price and a recommendation we will argue for, including the cases where the honest answer is a smaller build.
I worked with AppVertices on a mobile app project and was impressed by their professionalism and organized process from start to finish.
Nadim Husam
Head of Digital Initiatives, Leading Transportation Ministry
AppVertices delivered a solid app for our real estate business. Their technical skills and constant support, especially from Max, made the process worthwhile.
Amanda Clark
CEO/Founder, Htown App
AppVertices built a custom internal system that simplified our workflows across departments. The intuitive interface and performance made a real difference.
David Therrien
Head of Marketing, Manufacturing Company
As a CTO, I found their work exceptional. They delivered a secure, scalable dashboard with great usability and excellent post-launch support.
James Dailey
CTO, Technology Company
AppVertices developed our AR science app, and it exceeded expectations. Their team felt like a true partner from day one, and the results speak for themselves.
Maria Smith
Co-Founder, Scilens
We approached AppVertices to revamp the UI/UX of our online learning platform. Their design team transformed our user interface into an intuitive and engaging experience.
Allen Mitchell
CEO, Education Training Center
Security that is designed in at the data model rather than audited in at the end, because the second one is how a launch date slips.
TLS everywhere, platform keystores for anything on the device, and no secrets in the bundle — checked by the pipeline rather than by memory.
Biometrics, token rotation and session handling scoped to what the product actually risks, not to a checklist.
Every service, key and role starts with nothing and is granted only what it is demonstrably used for.
Automated scanning on every build, with upgrades handled on a schedule instead of after an advisory.
Non-Executive Director, AppVertices
Thirty minutes on what you are trying to build, with someone who will tell you if it is the wrong thing to build.
No deck and no discovery fee. You leave with a scope you can price and a recommendation we are willing to argue for.
Models put where they measurably help — triage, summarisation, retrieval — with the fallback path designed before the demo, because the fallback is what users meet on a bad day.
Work moved to the edge where the round trip is the cost, with devices that keep functioning when the link does not.
Key handling, custody and settlement treated as the hard parts they are, and built only where a ledger earns its place over a database.
Spatial interfaces for training, inspection and field work, scoped to the sessions people will actually sit through.

Four things that hold when the schedule gets tight, which is the only time any of them matter.
Reviewed code, tested branches and a pipeline that refuses a bad build — the same on week twenty as on week one.
We have shipped against New York procurement, New York compliance reviews and New York launch calendars, and we scope for them rather than discovering them.
Short phases that each end in an installable build, so progress is something you hold rather than something you are told.
SOC 2, HIPAA and the financial regimes your sector answers to, designed into the data model at the start instead of retrofitted before an audit.
Come in and walk through the problem with the engineers who would build it. If a call is easier, that works too.
Midtown Houston, 4201 Main St Suite # 200-122, TX 77002, United States.
An MVP is six to ten weeks from signed scope to a build in a store, and a mid-complexity product with integrations and a back end is three to five months. In New York the binding constraint is usually a compliance review or a partner's integration calendar, and that, rather than the engineering, is what sets the floor.
Tell us what you are building, who it is for and when it needs to be live. You will get a written scope, a realistic range, and a named engineer on the call rather than a sales deck.

You leave with a phase you can price and a recommendation we will argue for, including the cases where the honest answer is a smaller build.
Flows and screens drawn against real content and real device sizes, reviewed on a handset rather than on a desktop monitor at 50%.
Usability is settled here, while changing it is still cheap.
Short phases, each ending in an installable build. Frontend, backend and integrations move together so nothing waits on a dependency nobody owns.
The engineers who scoped it write it, which is why decisions made in week two can still be explained in week twenty.
Device and OS coverage taken from your analytics, not from the handsets in our drawer, plus performance, accessibility and the security checks the sector requires.
Automated on every build, so a regression fails the pipeline instead of the release.
Store submission, staged rollout and monitoring configured before launch day rather than during it.
Afterwards: OS releases, dependency upgrades and an on-call path — on an agreement with response targets, or handed to your team with the runbooks.
Security that is designed in at the data model rather than audited in at the end, because the second one is how a launch date slips.

Yes. OS releases, store policy changes, dependency upgrades and an on-call path, on a monthly agreement with the response targets written into it — or handed to your own team with the runbooks, which is common where an internal platform group already carries other systems.
Financial services, healthcare, retail and logistics make up most of the New York work, alongside SaaS and consumer products. Where a sector carries a regime — HIPAA, SOC 2, PCI — we build to it from the data model rather than auditing towards it later.
Fixed price per phase, against a scope you approve before it starts. Where the scope is genuinely unknowable up front we say so and run a short paid discovery to make it knowable, rather than pricing a guess.
Yes — multi-platform products, regulated data, legacy integrations and migrations off systems that cannot go down. If a piece of it is beyond what we would do well, we say which piece and why.
