Today, having mobile applications isn't enough for a New York business. Your potential client opens a smartphone on the L train, sees three or four similar offers, and decides in 5 seconds which one to engage. If yours is slow, unclear on mobile, or doesn't render correctly under iOS Safari with intermittent subway connectivity — you've lost that customer before they finished reading your headline. That's why investing in quality Mobile app design isn't a "luxury expense", it's a direct investment in revenue.
I'm Alex Filiuk, a Senior practitioner with 15 years of experience and a portfolio of 130+ projects. I deliver mobile applications for businesses in New York, across the US (San Francisco, LA, Boston, Austin), in Europe (London, Manchester, Edinburgh), and in Ukraine. On this page I've collected what's worth knowing for an NYC business owner before commissioning mobile app design: how the engagement works, USD pricing brackets, which mistakes destroy ROI, and which 2025-2026 trends actually matter for the NYC market.
NYC is one of the most app-saturated user populations on Earth — the average New Yorker has 80–120 apps installed and uses 11–14 daily. Getting installed is hard. Staying past day-7 is harder. App design isn't a 'pretty UI' problem — it's a behavioral-design problem where every tap, every notification, every onboarding step either compounds retention or accelerates churn. A poorly designed onboarding flow can drop day-1 retention from 70% to 35% with no other variable changing.
What quality mobile-app design delivers for an NYC business:
Naive mobile-app design is 'design beautiful screens in Figma'. The result is screens that look great in a portfolio but produce confusing, slow, churning apps in production. Real mobile-app design is a behavior-driven discipline: information architecture, onboarding optimization, gesture design, animation timing, accessibility, native-platform conformance.
A real NYC-grade mobile-app design engagement covers:
Mobile-app design pairs naturally with mobile-app development when you need both phases run by a coordinated team, eliminating handoff loss between design and build.
Across 15 years and 130+ projects, I've noticed NYC business categories have their own digital signature. Most-common requests for mobile-app design:
Different category, different approach — so I don't ship templates. Every engagement starts with discovery against your actual NYC market context.
I work via a transparent process that 130+ clients have completed end-to-end. Each phase has a fixed deliverable that you receive in your hands. No "wait a month while I design" — you know what's happening every week, with weekly Slack updates and one Zoom sync at 8am NYC / 3pm Kyiv.
NYC has a deep pool of talent — and rates that match. A typical Senior at a Manhattan agency: $180–280/hour. A 12-week engagement at a respectable Flatiron studio: $80,000–180,000. The work is excellent, but the cost makes it inaccessible for most early-stage startups, mid-sized DTC brands, and bootstrapped B2B SaaS companies.
The remote Ukraine-Senior model gives you:
All projects are quoted as fixed fee in USD, paid 50% upfront / 50% on delivery (or split into milestones for projects > $20K). No hourly invoices. If scope changes mid-project — we re-quote, you approve in writing, and the change is added with a clear delta.
Indicative ranges to set expectations (every quote is bespoke, but these brackets are realistic):
Discounts apply when you bundle services (e.g. design + development + SEO together) — typically 15-25% vs. ordering each separately.
The 7-hour difference between New York (EST/EDT) and Kyiv (EET/EEST) is the biggest concern most NYC clients raise — and it's the easiest to solve. The honest answer: most NYC startup founders and product teams already work async with Slack-first cadence. The remote-Ukraine engagement just formalises what's already happening internally.
My portfolio contains 130+ projects, including B2B SaaS for US founders, DTC brand sites for NYC and LA-based companies, and fintech dashboards for clients on the East Coast. For NDA reasons I can't list every client publicly — but on the discovery call I'll walk you through 5-10 most-relevant cases for your specific niche.

Fill out the contact form or message me through the channels in the footer. The first 60-90 minute call is free — we'll discuss your business, product goals, indicative scope, USD budget range, and timeline. If you have an existing site / app, I'll do a quick express-review and show you 3-5 issues that can be fixed in the first week, even before signing a full engagement.
