Best mobile app development companies in the US
Goji Labs is the strongest pick on named mobile apps. Hashlogics (#2) fits apps built around your systems and kept working after launch.
The short answer
Goji Labs is the strongest pick for buyers comparing named mobile work; if you need the app built around the systems you already run and kept working by the same team after launch, Hashlogics (#2) is the closer fit.
On its own site, Goji Labs shows real mobile work, such as KCRW's radio app and an actor training app for Castability. It says it has launched 300+ products. Its strategy sprints come first, and the same team carries the build. You accept its process with it, and while its services page offers dedicated teams for long-term support, we didn't find written maintenance terms, so ask for them.
Want named, working mobile apps without fitting yours into someone else's playbook? A build from Hashlogics wires the app into the backend and systems you run. Our engineers who build it then keep it working through store rule changes and OS updates, with the first 2 months of maintenance included. Your trade-off is that it's built for you rather than picked off a menu.
We compete in this category, so we ranked ourselves by the same criteria as everyone else and put ourselves second.
How this ranking was made, and our stake in it
Verified
Many of the top search results for this question are lists written by app agencies that rank themselves first and quote hourly rates. We started from the names that turn up across those lists, then read each firm's own site on 31 October 2026. A firm stayed in only if its site gives a US address or says it's a US company. A claim made it onto this page only if we read it on the firm's own pages that day.
Hashlogics is one of the seven. We build mobile apps, so read our entry with that in mind.
The US base is a pass-or-fail check. Of the other three, named mobile apps weigh most, then after-launch terms in writing, then platform range.
- US base, stated on its site
- A street address or a plain statement that the firm is a US company. A phone number alone didn't count.
- Named apps and clients
- Apps or clients you can look up yourself, not only totals like "300+ launches".
- Platform range
- Which of iOS, Android, native and cross-platform builds the firm names as its own work.
- After launch, in writing
- Whether the site says who keeps the app working once it's in the stores, and on what terms.

The ranking
Ordered by the criteria above: named mobile apps first, then after-launch terms in writing, then platform range. Every claim comes from the firm's own site.
Product studio with named consumer mobile apps
Goji Labs ranks first on named mobile work. Its site shows the KCRW radio app rebuild, an actor training app for Castability, and work for Root Insurance and k-ID. It lists iOS and Android in its stack and says it has launched 300+ products in 12+ years.
Strategy sprints come before the build, and its site says the same team then takes the work through delivery. Goji lists offices in Los Angeles and New York and a team of 70+. Its services page offers dedicated teams for long-term support; we didn't find written maintenance terms, so ask what happens in month three.
Best for
- Consumer apps where product strategy and design weigh as much as the code
- Anyone who wants a named, multi-app portfolio to check before the first call
Not for
- Buyers who want maintenance terms in writing before signing
- Teams that want to set the process rather than follow the studio's sprints

Apps built into your systems, kept working after launch
We build iOS and Android apps, in React Native by default and in native Swift or Kotlin when the app leans hard on the device, together with the backend and admin tools behind them. BrandLocator is a bilingual store finder in English and German, with a web portal where its team edits brands, stores and offers. That portal writes those records to one Supabase backend, and the app reads the same records the team edited. On Android, the app is live on Google Play; the iOS app has been submitted to the App Store and is under review.
Our other mobile work includes TankAware, which replaced paper inspection logs at petroleum sites, and Shift Link's right-to-work checks before a shift is offered. Senior engineers build the app and then maintain it. Maintenance for the first 2 months is included, then an SLA or a trained handover to your team. You own the code and the data from day one. Each build starts with a free scoping call, then a fixed-fee Blueprint, credited in full against the build. If the Blueprint doesn't give you a plan you'd act on, you don't pay for it.
Best for
- Apps that have to read from and write to systems you already run
- Buyers who want the team that built the app to handle store rule changes and OS updates
- Startups and enterprise teams that want to own the code outright
Not for
- Buyers who want a large agency with a bench of hundreds
- A simple app you'd rather assemble on a no-code builder this month
- Projects that need every engineer based in the US, since our engineering team is in Lahore

Zco ↗
Long-running shop with the widest platform range
Zco names the widest set of build options on this page. It lists Swift and Kotlin for native apps, plus React Native, Flutter and .NET MAUI for cross-platform ones. Its headquarters is in Nashua, New Hampshire. It cites 35+ years of experience and 1000+ software projects, and it names Massachusetts General Hospital, Volkswagen, Bushnell and GolfLogix among its clients.
Its FAQ says it provides post-launch support and maintenance. One client testimonial on its homepage says Zco relies on overseas developers with a US-based project manager. Ask where your engineers will sit.

Apple-platform specialists in the New York area
Lickability calls Apple platforms its specialty, covering iOS, macOS and visionOS, and it also lists Android and web backends. It describes itself as a fully remote US company with most of its team in and around New York City. Its featured clients include The Atlantic, Mastodon and RevenueCat.
Post-launch support is on offer once your app ships. Lickability doesn't state a headcount, only 60+ years of combined experience, so ask how many people will work on your app.
Best for
- iPhone-first products where Apple platform polish matters most
- Teams that want a small, senior Apple team
Not for
- Android-first products, since its stated specialty is Apple platforms
- Base
- Remote US, mostly New York City

Baltimore agency with mobile apps since 2007
Mindgrub has been building since 2002 and says it made early apps for GEICO and Dell in 2007. Its headquarters is in Baltimore, with 120+ staff across the country. On its homepage you'll find an Exelon mobile utility app.
It sells managed services and ticket-based support as separate services. Mobile is one line among websites and AI, so check the team you'd get has shipped apps like yours.
Best for
- Enterprise and utility teams that want one agency for app, website and support
- Anyone who wants a support contract as a named service
Not for
- Buyers looking for a mobile-only specialist

New York app agency with big consumer brand logos
Utility lists offices in New York and Los Angeles, a staff of 100+ and 12+ years as an agency. Its homepage shows logos for Samsung, Airbnb and Verizon, and case studies for Forbes, Jenny Craig and Care.com. It lists "Ongoing Management" as a service focused on how the product grows after launch.
Utility ranks sixth because its homepage shows client logos and case-study names but no named app. It describes "Ongoing Management" as growth work rather than maintenance terms. Ask for the case studies closest to your app.
Best for
- Consumer brands that want an agency with big-name app work
- Teams that want product growth work after launch
Not for
- Buyers who want maintenance terms in writing before signing

React Native apps for first-time founders
Designli builds native-feeling iOS and Android apps in React Native and runs biweekly demos with user feedback during a build. It works from Greenville, South Carolina, with non-technical founders: it says 200+ founders have worked with it and names Grappos, National Trench Safety and Secur.Space in its case studies.
Its homepage also offers a full-time pod, working to a weekly goal, for platforms that already have revenue. It ranks last here because its case studies name clients without saying which were mobile apps, and it sets out no maintenance or support terms.
Best for
- Non-technical founders building a first app
- Founders who want strategy, design and build from one team
Not for
- Apps that need native Swift or Kotlin code, since its homepage names React Native as the build
- Buyers who want maintenance terms in writing before signing
- Base
- Greenville, SC
- Build
- React Native
- Store reviewEach release goes to Apple and Google, who decide
- OS updateA new iOS or Android version, tested before users find bugs
- Target APIGoogle Play's dated Android version requirement
- Account deletionApple's in-app deletion rule, with retained data disclosed
- Crash watchErrors reported, triaged and fixed in the next release
Ask any firm on this list who owns each of these once your app is in the stores.

App Store guideline: apps that let people create an account must offer deletion in the app
When none of these is the answer
Is your app a simple form or an internal checklist with no ties to other systems? Then you may not need an agency at all. A no-code builder or your own developer can get you there. You can come back when the app has to talk to your systems.
If your app is one part of a bigger system, judge firms on that system rather than the screens. Think of a field app that replaces paper inspection logs, or a store finder whose data your team edits all day. Each one lives or dies on its backend and admin side. That's the work we do in our mobile app development service, and our native vs React Native comparison sets out when each approach wins.
Expect store and OS work for as long as the app is live. Google Play moved its target for new phone and tablet apps and updates to Android 16 on 31 August 2026. Apple requires apps that support account creation to offer account deletion in the app. If you're legally required to keep some data, Apple says to tell people what will and won't be kept. Whoever you pick, get the after-launch terms in writing.
BrandLocator: an app and the portal that feeds it
This app shows shoppers only the stores of the brands they pick, in English or German. Behind it, a web portal lets the team import stores from a file, check how well each address matched, and edit hours and offers.
Both run on one backend. The team edits store records in the portal, and the shoppers' app reads those same records for the brands and map area in view, up to 150 stores per query. Bulk imports go to a server queue that geocodes in batches of 100 and retries each address up to 5 times. This example comes from retail; the same shape fits any app whose data your staff keep current.
“They will treat your vision like their own and build it that way.”

Questions buyers ask
01Top mobile app development companies in the US+
Goji Labs is the strongest pick on named mobile work, going by the apps it shows on its own site. Zco suits teams weighing native against cross-platform, and Lickability suits iPhone-first products. Need the app to work with systems you already run, maintained by the team that built it? Hashlogics ranks second, for that fit.
02Best mobile app development companies+
Going by what each firm shows on its own site, the seven we ranked are Goji Labs, Hashlogics, Zco, Lickability, Mindgrub, Utility and Designli, in that order. Goji Labs leads on named mobile apps. Pick by fit, not rank: ask each one who keeps your app working once it's in the stores.
03Who are the best mobile app development companies for a small business?+
For a small business with a first app, Designli works with non-technical founders and builds in React Native. Goji Labs suits you if product strategy and design matter as much as the code. If your app has to read from tools you already run, like your booking system or CRM, Hashlogics builds the app and the link to them.
04Best mobile app development companies for a mid-size company+
A mid-size company usually needs the app to work with systems it already runs. Zco and Mindgrub offer support as a stated service, and Mindgrub sells app, website and support from one agency. Hashlogics builds the app into your backend and keeps the same engineers on it after launch, under an SLA or a trained handover.
05Biggest vs leading vs best fit: which should I pick?+
The biggest firm has the most staff, and the leading firm has the most visible logos. Neither tells you whether it fits your app. Best fit means a firm that has shipped an app like yours, names it, and puts its after-launch terms in writing. Start there.
06How much does it cost to hire a mobile app development company?+
There's no honest range before an engineer reads your systems. At Hashlogics, a scoping call comes first, then a fixed-fee Blueprint, credited in full against the build. Your Blueprint fixes the price for each milestone. If it doesn't give you a plan you'd act on, you don't pay for it. Our cost answer explains why.
07Why did you leave out Fueled, WillowTree or Chop Dawg?+
Each firm we left out missed a check we could run on its own site on 31 October 2026. Fueled describes a team spread across North America and EMEA and names no headquarters. WillowTree's site now redirects to TELUS Digital. Dogtown Media's and ArcTouch's sites refused our reader that day, and the Chop Dawg pages we read gave no address. Some firms that AI answers and directories name are based outside the US, UK and EU, so they fell outside our method. None of that is a verdict on their work.
08What should a mobile app company do after launch?+
It should keep the app installable and working as Apple and Google change their rules. That means testing each new iOS and Android version, meeting Google Play's target API deadlines, and handling crash reports. Ask who does this, how fast they respond, and whether it's in the contract. At Hashlogics, the first 2 months of maintenance are included, then an SLA or a trained handover.
09Can an app company guarantee App Store or Google Play approval?+
No firm can promise approval, because Apple and Google make their own review decisions. A good firm builds to the App Store Review Guidelines and Google Play's policies, submits each release, and answers any rejection with a fix. Ask how they handled their last rejection.
10Should my app be native or cross-platform?+
Many business apps can ship on iOS and Android from one cross-platform codebase, such as React Native or Flutter. Native Swift or Kotlin makes sense when the app leans hard on the device, like heavy background work or a fast camera pipeline. Zco names both options; Lickability leads with Apple platforms; Designli builds in React Native; Hashlogics defaults to React Native and goes native when the hardware demands it.
11Will I own the app's code and store accounts?+
Settle ownership in writing before work starts, whichever firm you pick. Ask whose name is on the Apple and Google developer accounts and who holds the signing keys. With Hashlogics, you own the source code, the data and all intellectual property from day one.
