Most app projects don’t fail in development. They fail at scope, when the feature list grows faster than the budget. Comfygen has shipped 550+ apps since 2019 for clients in 30+ countries, and the first thing you get back is a scope and a cost range, before anyone signs anything.
Android, iOS and cross-platform builds, from a startup MVP to an enterprise rollout. Our team handles design, development, testing, store submission and the support that comes after launch.
Kotlin and Java builds using Jetpack Compose, tested across the device sizes and Android versions your users actually run. Our Android app development team ships to the Play Console with the signing, policy checks and staged rollout handled.
Kotlin-first builds with Jetpack Compose UI
Tested on real devices, not just emulators
Play Console submission and staged rollout
Wear OS and Android TV builds where you need them
Best for: reach, especially in India, Southeast Asia and Latin America.

Swift and SwiftUI apps built to Apple’s Human Interface Guidelines, which is what gets an app through review the first time instead of the third. Our iOS app development work covers iPhone, iPad and Apple Watch, with Keychain-backed credential storage as standard.
Swift and SwiftUI, with UIKit where a project needs it
Built to Apple’s review guidelines from day one
iPhone, iPad and Apple Watch targets
App Store submission, signing and provisioning handled
Best for: higher-spend markets such as the US, UK and UAE.
One codebase for Android and iOS using Flutter or React Native, with native modules dropped in where a feature needs device-level speed. This typically cuts 30% to 40% off the cost of building twice.
Single codebase across Android and iOS
Native modules for camera, Bluetooth and background tasks
One release cycle instead of two
Lower maintenance cost over the app’s life
Best for: getting to both stores on one budget and one timeline.
Apps that connect to the systems your business already runs on. Our team builds REST and GraphQL APIs into ERP, CRM and payment platforms, with role-based access, single sign-on and offline-first data sync so field staff can work without signal.
SSO and role-based permissions
Offline mode with automatic sync on reconnect
ERP, CRM and payment gateway integration
Audit logs and crash analytics built in
Best for: operations teams, field staff and internal workflows.
A working product with the two or three features that prove the idea, built in 6 to 10 weeks. You launch, you get real user data, and you decide what to build next from evidence instead of guesses.
Scope workshop to cut the feature list down
One platform first, usually
Analytics wired in before launch
A build you can extend, not throw away
Best for: founders who need users in front of the product this quarter.
Pre-built platforms you brand as your own and launch in weeks. Our white label app development solutions cover delivery, booking and marketplace models, with your logo, colours, payment gateway and domain.
Launch in weeks, not months
Your branding, your payment gateway, your domain
Customer, provider and admin apps included
Source code handed over on completion
Best for: resellers and businesses entering a proven category.
Comfygen takes over apps built by someone else. Code audit first, then a written list of what’s broken, what’s risky and what it costs to fix, before any work starts.
Code and security audit with a written report
Framework and OS version upgrades
Migration between native and cross-platform
No user data loss and no forced re-login
Best for: apps whose original developer is gone or unresponsive.
Apple and Google change their requirements every year, and an app that isn’t updated eventually stops being accepted. Our maintenance plans cover OS compatibility, security patches and performance work, and you can read our breakdown of what app maintenance costs over a full year.
OS compatibility updates each release cycle
Security patching and dependency upgrades
Crash monitoring and performance tuning
Agreed response times on one, two or three year plans
Best for: any app already live in the stores.
Smartphone subscriptions worldwide reached 7.3 billion in 2025 and are forecast to pass 7.9 billion by 2028, according to Statista. Your customers are already on mobile. The only question is whether they find you there.
For startups, an app proves the idea with real usage data instead of guesses. For enterprises, it cuts support cost and keeps customers buying without a sales call.
Mobile app development costs $15,000 to $250,000. A single-platform MVP runs $15,000 to $30,000, a standard app on both platforms runs $30,000 to $70,000, an on-demand platform with customer, provider and admin apps runs $60,000 to $120,000, and a regulated enterprise app runs $100,000 to $250,000 or more. Three things decide where you land: how many platforms, how much of the backend is custom, and whether the app has to meet a compliance standard.
| What you’re building | Range | Timeline | What pushes the number up |
|---|---|---|---|
| MVP, one platform | $15,000 – $30,000 | 6–10 weeks | A custom backend instead of Firebase |
| Standard app, Android + iOS | $30,000 – $70,000 | 3–5 months | Custom UI, payments, third-party APIs |
| On-demand platform (3 apps) | $60,000 – $120,000 | 5–8 months | Live tracking, dispatch logic, multi-vendor |
| Enterprise or regulated app | $100,000 – $250,000+ | 8–14 months | HIPAA or PCI work, ERP integration, security audits |
A simple app takes 6 to 10 weeks. A standard app on both platforms takes 3 to 5 months. A complex platform takes 5 to 8 months, and a regulated enterprise app takes 8 to 14 months. Design and discovery are usually 15% to 20% of the total, testing another 15%, and store review adds 2 to 7 days at the end.
| Phase | Simple app | Standard app | Complex platform |
|---|---|---|---|
| Discovery and scope | 1 week | 2 weeks | 3–4 weeks |
| UI/UX design | 1–2 weeks | 3–4 weeks | 5–8 weeks |
| Development | 3–5 weeks | 8–12 weeks | 16–24 weeks |
| Testing and QA | 1 week | 2–3 weeks | 4–6 weeks |
| Store submission | 2–7 days | 2–7 days | 2–7 days |
| Total | 6–10 weeks | 3–5 months | 5–8 months |

Pick native when the app needs maximum performance or deep hardware access. Pick cross-platform when you want both stores on one budget, which covers most business apps. Pick a PWA when users don’t need to install anything, such as a catalogue, a news product or a kiosk screen.
| Factor | Native (Swift / Kotlin) | Cross-platform (Flutter / React Native) | PWA |
|---|---|---|---|
| Cost | Highest, two codebases | 30–40% less than two native builds | Lowest |
| Time to both stores | Longest | Shortest | No store needed |
| Performance | Best | Close to native for most apps | Browser-limited |
| Hardware access | Full | Full with native modules | Limited |
| Maintenance | Two codebases forever | One codebase | One codebase |
| Good fit | AR, video editing, games | Marketplaces, booking, delivery | Catalogue, news, kiosk |
| Poor fit | Tight budgets | Heavy 3D or real-time graphics | Anything needing push on iOS at scale |
We developed and delivered ZatPat Ride, an on-demand food delivery and ride-hailing app platform featuring real-time GPS tracking, rider dispatch logic, multi-vendor menus, and smooth digital checkout.
Case StudyOur expert developers are here to make it happen. From concept to launch, we’ll build your app with precision and innovation.
Fixed Scope
Best for defined MVPs and rebuilds
An agreed feature list, a fixed price and a fixed delivery date. Scope locks after discovery, and changes are quoted separately.
Dedicated Team
Best for ongoing roadmaps
Developers working in your tools, your sprints and your repository, reporting to you. Scale the team up or down each month.
Takeover and Support
Best for existing apps
Comfygen takes on apps built by someone else. A code and security audit comes first, with a written cost report.
Not sure which fits? Send the brief and our team will recommend one, with reasoning. Talk to us
Recommendation engines, in-app search that understands intent, and document scanning that reads what’s on the page. Our AI development team builds these as features inside the app, not bolted on afterwards.
Virtual try-on for retail, 3D product placement for furniture and home goods, and training simulations for industrial clients.
Apps that pair over Bluetooth Low Energy and read live device data, built alongside our IoT development work for wearables, smart home and fleet hardware.
Wallet features, token handling and on-chain records inside a mobile app, backed by the same team that does our blockchain development work.
AWS, Google Cloud and Azure backends with auto-scaling, caching and CDN delivery, so the app holds up when traffic spikes.
Your goals, users and feature list, turned into a written scope with a cost range.
Screen-by-screen structure and user flows, mapped out before anyone writes a single line of code.
High-fidelity screens plus a clickable prototype you can tap through before any development begins.
Two-week sprints building app and backend, with a working demo at every sprint end.
Manual and automated testing across real devices, OS versions and slow or patchy network conditions.
Metadata, screenshots, signing and provisioning handled, plus the App Store and Play review process.
Crash monitoring, security patches, OS compatibility updates and new feature releases long after launch.

Blockchain TechnologyComfygen holds ISO 27001 for information security, ISO 9001:2015 for quality management, and ISO/IEC 20000-1:2018 for IT service management. Apps are built to meet GDPR, HIPAA and PCI DSS where a project requires it, plus Apple’s and Google’s own store policies.
Headquarters in Jaipur, plus offices in Toronto, Canada and Euskirchen, Germany. That means working hours overlap for clients in North America and Europe, not just email sent overnight.
400+ clients, and almost all of them come back for a second project. That number is the one worth checking, because it measures what happened after launch.
Information security is audited, not claimed. For healthcare, fintech and enterprise buyers, this is usually the first question procurement asks.
Source code, documentation and IP transfer to you on completion. No licence fees, no lock-in, no hostage situation if you change vendors.
Sprint demos throughout the build, a named project manager, and repository access from day one. You see progress, not status reports.
Mobile, blockchain, AI and web since 2019, covering healthcare, fintech, delivery, education, gaming and on-demand platforms.
Planning to run the build with your own team in charge? Hire mobile app developers from Comfygen on a monthly basis and they work in your tools, your sprints and your repository.

Between $15,000 and $250,000. A single-platform MVP runs $15,000 to $30,000, a standard app on both platforms runs $30,000 to $70,000, an on-demand platform with three apps runs $60,000 to $120,000, and a regulated enterprise app runs $100,000 or more. Platform count, how much of the backend is custom, and compliance requirements are what move the number.
6 to 10 weeks for a simple app, 3 to 5 months for a standard app on both platforms, and 5 to 8 months for a complex platform. Add 2 to 7 days for App Store or Play Store review at the end.
Cross-platform for most business apps, because one codebase covers both stores and costs 30% to 40% less than building twice. Native when the app needs maximum performance or deep hardware access, such as AR, video editing or games.
You do. Source code, documentation and intellectual property transfer to you on completion, with no licence fees and no restrictions.
Yes. Comfygen signs an NDA before any detailed discussion, and you can ask for a copy before you send your brief.
Launch on one platform first if the budget is tight or the idea still needs validating. Launch on both together if your users are split across them and you’re entering a category where competitors already have both. Android reaches more users globally, iOS users spend more per head.
Yes. Our team starts with a code and security audit and gives you a written report on what’s broken, what’s risky and what fixes cost, before any development begins.
Comfygen handles the whole submission: metadata, screenshots, signing, provisioning, data safety declarations and the review process itself. Apps are built to Apple’s and Google’s guidelines from the first sprint, which is what avoids rejection.
Our team fixes the issue and resubmits at no extra cost. Rejections are usually about permissions, privacy declarations or payment handling, and those are reviewed before the first submission to keep it to one round.
Encryption in transit and at rest, certificate pinning, credentials stored in Keychain on iOS and Keystore on Android, role-based access, and a vulnerability assessment before launch. Comfygen is ISO 27001 certified for information security.
Offices in Toronto and Euskirchen give working-hour overlap with North America and Europe. Sprint demos and calls are scheduled in your time zone, not ours.
Typically 15% to 20% of the original build cost per year, covering OS compatibility, security patches, bug fixes and small feature work. Our full breakdown of app maintenance costs covers how that splits across the year.
Yes. Encrypted protected health information, audit logging, role-based access and a signed BAA on request. See our healthcare app development work for the full scope.
Outsource when you need to launch within months and don’t want to spend them hiring. An agency already has designers, developers, QA and a project manager. Hire in-house when you have a long-term product roadmap and the app is core to the business, not a project with an end date.
