A Senior Mobile App Development Company That Ships What You Scoped

The short answer

Digital Heroes is a custom mobile app development company that builds iOS, Android, and cross-platform apps for funded startups and enterprise teams. You work with senior engineers on fixed timelines, and you own 100% of the source code and IP. We have delivered 2,000+ projects across 55+ countries, and every engagement drives toward a shipped, maintainable product, not a demo.

What does Digital Heroes actually build?

We build production mobile apps that carry real transactions, real users, and real revenue. That means native iOS (Swift/SwiftUI), native Android (Kotlin/Jetpack Compose), and cross-platform apps in React Native or Flutter when a shared codebase makes sense for your budget and roadmap. On the back of that sits the part most cheap builds skip: the API layer, the database, authentication, payments, push infrastructure, and the CI/CD pipeline that lets you ship updates every week instead of every quarter.

Typical work we take on as a mobile app development company:

  • Consumer apps with accounts, social features, and in-app purchases or subscriptions
  • Marketplace and on-demand apps with two-sided flows, matching, and real-time status
  • Fintech and health apps where security, audit trails, and compliance are non-negotiable
  • Enterprise field and operations apps that sync offline and integrate with SAP, Salesforce, or a custom ERP (Enterprise Resource Planning)
  • Rescue projects, where a previous team left a half-working codebase and you need it stabilized and finished

Why choose a senior custom partner over a cheap shop?

The price gap between a $12,000 offshore build and a $90,000 senior build is not a markup. It is the difference between an app that demos on one phone and an app that survives ten thousand users, an App Store review, and your own team maintaining it a year later. Cheap builds are almost always junior engineers copying a template, and the cost shows up later as crashes, rejected submissions, and a rewrite.

Here is what a senior custom partner changes:

  • Senior engineers, not a rotating junior pool. The people who scope your app are the people who build it. No hand-off to a team that never read the spec.
  • Fixed timelines with real milestones. We commit to dates for design sign-off, beta, and store submission, and we hit them because we scope honestly up front.
  • You own the source code and IP outright. Full repository access, no licensing traps, no proprietary framework that locks you into us. If you fire us, you keep everything and can hire anyone to continue.
  • 2,000+ projects across 55+ countries. We have already hit the edge cases your app will hit: payment gateways per region, App Store rejection reasons, offline sync conflicts, and scale.

What is your mobile app development process?

Every project runs through the same six stages, so you always know what happens next and what you are approving.

  1. Discovery. We pin down the actual scope, the must-have first release, and what to cut. This is where we tell you the honest truth about timeline and cost before a line of code exists.
  2. Design. Wireframes then high-fidelity UI and a clickable prototype. You see and approve every core screen before we build it.
  3. Build. Two-week sprints with a working build at the end of each. You test on your own device the whole way, no big-reveal surprise at the end.
  4. QA. Manual and automated testing across real devices and OS versions, plus performance, security, and store-guideline checks.
  5. Launch. We handle App Store and Google Play submission, review responses, and the production release.
  6. Support. Post-launch maintenance, monitoring, OS-update compatibility, and a roadmap for version two.

What do you get as deliverables?

A Digital Heroes engagement is not just a binary in a store. You receive the whole asset, documented and transferable:

  • Native or cross-platform app for iOS and Android, submitted and live
  • The complete backend, API, and database, deployed to your cloud account
  • Full source-code repository with commit history and branch access
  • Admin dashboard or CMS where the app needs one
  • Technical documentation, architecture notes, and API reference
  • CI/CD pipeline so your team can ship updates without us
  • Design files and a component library
  • A post-launch support window and a costed version-two roadmap

What are your engagement models and cost ranges?

We price by the shape of the work, not by a headcount you cannot see. These ranges reflect our own delivery experience across the last several years, not a public survey. Where you land depends on platform count, backend complexity, and integrations.

Engagement modelBest forTypical costTimeline
MVP buildStartups validating one core flow on iOS or Android$25,000 to $60,0008 to 14 weeks
Full custom appFunded startups launching both platforms with a real backend$60,000 to $150,0004 to 7 months
Enterprise buildComplex integrations, compliance, offline sync, multiple roles$150,000+6 months+
Dedicated teamOngoing roadmap, a squad embedded month to monthFrom ~$12,000 / month per senior engineerRolling
Rescue / auditInheriting a broken or stalled codebaseFrom $8,000 (audit), build quoted after2 to 4 weeks to assess

If your number is well below the MVP band, we will tell you plainly rather than take the project and cut corners. A serious two-platform app with payments and accounts does not get built well for $10,000, and we would rather lose the deal than ship you something you will pay to rebuild.

When is Digital Heroes the right fit, and when is it not?

Honesty here saves everyone a bad engagement.

We are a strong fit if:

  • You are funded or revenue-backed and treating this app as a real product, not a side experiment
  • Your app needs custom logic, real integrations, security, or scale that a template cannot carry
  • You want senior engineers, fixed dates, and to own everything you pay for
  • You have a previous build that stalled and need a senior team to finish or rescue it

We are probably not your best fit if:

  • You need a simple, brochure-style app and a $5,000 no-code tool would genuinely do the job
  • You want the lowest possible price above all else, because we compete on outcome, not on being cheapest
  • Your requirements are still a rough idea with no budget, in which case a short discovery call is the right first step, not a full build

How do you start a mobile app project with us?

The first move is a discovery call, not a contract. You describe what you want to build, who it is for, and where your budget sits. We come back with an honest read on scope, timeline, the right engagement model, and a real number, before you commit anything. If we are not the right partner for your project, we will say so and point you somewhere better.

You get senior engineers, fixed timelines, full IP ownership, and a partner that has shipped 2,000+ projects across 55+ countries. Book a call to scope your app and get a straight answer on cost and timeline.

FAQ

Frequently asked questions

How much does it cost to hire a mobile app development company?

For a serious custom app, expect $25,000 to $60,000 for a single-platform MVP, $60,000 to $150,000 for a full two-platform app with a real backend, and $150,000+ for enterprise builds with compliance and complex integrations. These ranges come from Digital Heroes' own delivery experience. Where you land depends on platform count, backend depth, and integrations, which we pin down in discovery before quoting.

Do we own the source code and IP?

Yes, completely. You get the full source-code repository, deployed to your own cloud account, with commit history and branch access. There is no proprietary framework locking you in and no licensing trap. If you ever part ways with us, you keep everything and can hand it to any other team to continue.

Should I build a native or cross-platform app?

Native (Swift for iOS, Kotlin for Android) is the right call when you need peak performance, deep platform features, or a heavy graphics or hardware experience. Cross-platform (React Native or Flutter) shares one codebase across both stores and usually costs less and ships faster, which suits many startups. We recommend based on your budget, roadmap, and performance needs in discovery, not by defaulting to one approach.

Can you finish or rescue an app another team started?

Yes. Rescue projects are common for us. We start with a fixed-scope audit, typically from $8,000, that assesses the codebase, tells you honestly what is salvageable, and estimates the work to stabilize and finish it. From there we quote the build. Sometimes the right answer is a targeted rebuild rather than patching, and we will tell you which it is.

How long does it take to build a mobile app?

A single-platform MVP typically ships in 8 to 14 weeks, a full custom two-platform app in 4 to 7 months, and enterprise builds run 6 months or more. We commit to fixed milestone dates for design sign-off, beta, and store submission because we scope honestly up front, and you get a working build at the end of every two-week sprint along the way.

Is buying a template app from CodeCanyon cheaper than hiring a developer?
Upfront, yes: templates sell for $30 to $200 against tens of thousands for custom work, but the total cost often flips within the first year. Templates commonly arrive with outdated dependencies, no ongoing updates, and code you cannot inspect before buying, and heavy customization of someone else's codebase can cost more than building clean. They are fine as a throwaway prototype and a poor foundation for an app your revenue depends on.
We run everything on spreadsheets and Airtable. How do we know it's time for custom software?
The reliable signals are re-typing the same data into multiple tools, one employee acting as human middleware between systems, and errors appearing in handoffs between teams. Hard limits force the issue too: Airtable's Team plan caps at 50,000 records per base, and Business costs $45 per seat per month, so a 20-person team pays about $10,800 a year for a tool it has already outgrown. When workarounds consume more hours than the tools save, the spreadsheet era is over.
What does it cost to run a mobile app every month after launch?
Budget three buckets: store fees (Apple charges $99 a year, Google Play a one-time $25), hosting and infrastructure, and per-use services like maps, SMS, or payment processing. Across Digital Heroes client projects, a small production app runs $150 to $500 a month all-in before any new feature work. The number scales with usage, so ask your agency for a cost projection at 1,000 users and at 50,000, not just at launch.
What does app maintenance actually include after launch?
Four things: adapting to the major iOS and Android versions Apple and Google ship every year, updating third-party libraries before they break or go insecure, monitoring and fixing crashes, and keeping up with changing store policies. New features are not maintenance; they belong in a separate roadmap budget. An app that gets none of this usually starts visibly misbehaving within a year or two as operating system changes pile up.
Can I move my users and data off a no-code platform into a custom app?
Your data can move, but your users' passwords cannot. Platforms like Bubble let you export records through CSV files or their API, but password hashes never leave the platform, so a migration needs a password reset or email login flow for every existing user. Plan the export before you hit the platform's pricing or capacity ceilings, because migrating under pressure is how data gets lost.
How do I vet a mobile app development agency before signing?
Ask for three apps they built that are live in the stores right now, then download them and read the recent reviews yourself. Ask exactly who will work on your project, because some agencies sell with senior staff and deliver with juniors or subcontractors, and request one past client you can call. An agency that stalls on any of those three requests is answering your question.
What tech stack should I ask for so I am not locked into one vendor?
Ask for a mainstream stack: Flutter or React Native for the app, or Swift and Kotlin if you go native, with a backend on widely hired technology like Node.js and PostgreSQL. Stack choice matters less for features than for who can maintain the code later, and every option above has a deep hiring pool. Refuse agency-proprietary frameworks and platforms only that vendor understands, since they turn every future change into a captive negotiation.
What should I have ready before I contact an app development agency?
A one-page brief beats a formal specification: the problem the app solves, who will use it, the 10 to 15 features version one must have, two or three apps you want it to feel like, and your budget range and deadline. You do not need wireframes or a technical document; producing those is what the agency's discovery phase is for. A written feature list also makes quotes comparable, because every vendor is finally pricing the same thing.
How much should a small business budget for its first custom app or website?
For a focused first build, most small businesses land between $8,000 and $60,000: roughly $8,000 to $45,000 for a custom website and $25,000 to $60,000 for an internal tool or simple web app, based on Digital Heroes delivery across 2,000+ projects. Customer-facing products with payments, logins, or a mobile app start around $40,000. Quotes far below these bands usually mean a template with your logo on it, not software shaped around your workflow.
Does my app need to be HIPAA or GDPR compliant?
HIPAA applies if the app handles US health information for providers, insurers, or their vendors; GDPR applies the moment you have users in the EU, wherever your company is based. Both reshape the build: HIPAA requires hosting vendors that will sign a business associate agreement, and GDPR requires consent, data export, and account deletion flows. No-code platforms generally will not sign a business associate agreement on standard plans, which by itself pushes most health apps to custom development.
What changes when my app grows from 1,000 to 100,000 users?
Scaling from 1,000 to 100,000 users mostly changes the backend and the bills, not the app on the phone. Expect database tuning, caching, and a move off entry-level hosting tiers, with infrastructure costs climbing from tens of dollars a month into the hundreds or low thousands. This is also where no-code backends hit hard ceilings, Bubble's workload unit pricing being the classic example, which is why products expecting real scale either start custom or plan the migration early.
Why do agencies charge for a discovery phase instead of quoting for free?
Because an accurate quote requires real work: mapping your workflows, finding the edge cases, and writing a specification, which typically takes 1 to 3 weeks and costs $2,000 to $10,000 at Digital Heroes depending on system complexity. You leave discovery owning a written spec and a fixed price you can take to any vendor, so the money is not locked into one agency. Free estimates are guesses, and the guess usually becomes your budget overrun six months later.
How many SaaS seats do we need before building custom becomes cheaper?
The crossover usually shows up between 20 and 50 seats on premium tiers. Salesforce Enterprise lists at $165 per user per month, so 40 users cost about $79,000 a year in subscriptions, which is real money against a custom system you would own outright. Run the comparison over three years: if subscription spend beats the build cost plus 15-20% annual maintenance, custom wins on price before you even count workflow fit.
How do I calculate whether custom software will pay for itself?
Divide the build cost by the monthly benefit, where benefit is hours saved times loaded hourly cost, plus subscription fees replaced, plus any revenue the software unlocks. Three staff saving 10 hours a week each at a $40 loaded rate is about $62,000 a year, which pays back a $60,000 build in roughly 12 months. Across Digital Heroes internal-tool projects, 12 to 24 months is the normal payback range, and anything projecting under 6 months usually means the spreadsheet is hiding costs.
