iOS and Android from one codebase
React Native or Flutter by default, and native Swift or Kotlin when the app needs it.
The Problem
Apps That Break in Your Customers' Hands
Most apps look fine on the developer's phone. The trouble starts on older devices, weak signal, store review, and the first OS update after launch.
01 · Demo-only testing
Your app passed every demo but froze on older Android phones.
Every release gets tested on real phones, older models included.
02 · Weak connections
Login loops fail on hotel Wi-Fi.
Design starts from the devices and signal your customers actually have.
03 · Store rejection
Apple rejected the first submission over missing account deletion.
Account deletion, privacy labels, and payment rules go into the first sprint.
04 · Bad reviews
Early reviews sink while every fix waits in store review.
Crash monitoring and updates keep fixes moving after launch.
Your app passed every demo on the latest iPhone. Then real customers installed it. Screens freeze on an older Android phone, the login loop fails on hotel Wi-Fi, and push notifications arrive twice or not at all. Apple rejects the first submission because account deletion is missing. Reviews start at 2 stars, and every fix now waits in a store review queue while your customers uninstall.
Our fix starts with how your customers actually use their phones: the devices they own, the signal they get, and what the stores require. Then we build both platforms from one codebase, test every release on real phones, and plan store rules into the first sprint. Your app launches ready for review, not rewritten after its first rejection.
Tested on the phones customers own
Your app runs on actual devices from both platforms, including older models, before every release.
Store rules planned early
Account deletion, privacy labels, and payment rules go into the first sprint.
One codebase, two stores
React Native or Flutter keeps both apps' features in step for one budget.
Our App Development Process
From App Idea to Both App Stores in Five Steps
Our mobile app development services follow five steps. You approve each one, and you can install test builds on your own phone from the first sprint.
In a free discovery call, you walk us through your users, must-have features, and the phone features the app needs. You get a release plan for both stores and a recommended approach: React Native, Flutter, or native.
What's Included
What You Get With Custom Mobile App Development
Your app, the backend behind it, and the store work to publish it. Everything is tested on real phones and released under accounts you own.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built mobile apps and booking flows for.
Our Autocar automotive app had a very different challenge. We needed customers to be able to browse vehicles, check details, and move through the enquiry process without getting lost in a complicated interface. Our first concern was performance because we knew a slow app would hurt the experience immediately. DeveloperLook helped simplify the screens, improve the user flow, and make the app feel much more responsive across different devices. I remember testing it on an older phone and thinking, ‘Okay, this actually feels like a proper product now.’ That was probably the moment I knew we had made the right decision. Even after launch, they continued helping us with fixes and improvements instead of treating delivery as the end of the relationship
We came to DeveloperLook because our appointment booking process was becoming a mess. Customers were dropping off halfway through booking, staff were dealing with unnecessary calls, and we were losing time fixing things that should have been simple. I was honestly nervous about rebuilding the whole experience because I didn’t want to end up with another complicated system. The team walked us through the user journey screen by screen and showed us where the friction was coming from. They simplified the booking flow, connected the necessary services, and made it much easier for customers to get from choosing a service to confirming an appointment. The biggest relief came after launch. When we found a few issues in the first weeks, the team actually helped us resolve them instead of disappearing once the project was delivered. That kind of after-launch support meant a lot to us.
We needed an HR attendee app for our employees, but the problem was that we didn’t really know how to turn our requirements into something people would actually use. We had attendance tracking, leave requests, notifications, and a few internal workflows in mind, but everything felt disconnected at the beginning. DeveloperLook took the time to understand how our HR team actually worked before building anything. The final app made those daily tasks much simpler, especially for employees who weren’t particularly tech-savvy. What really stood out to me was the support after launch. When we had questions or needed small changes, we weren’t pushed aside. That gave me a lot more confidence in rolling the app out across our team.

Work Culture
Why Businesses Trust Us to Ship Their App
Your app runs on devices you don't control, in stores with their own rules. These habits keep your releases smooth, from the first prototype to the latest OS update.
Tested on real phones
We test every release on real iPhones and Android phones, including older models, not only on simulators. The crashes your users would find show up on our desk first.
Store rules built in
We plan account deletion, privacy labels, and payment rules from the first sprint. Store review checks don't ambush your launch week.
One codebase, two stores
React Native or Flutter lets one team ship both apps with the same features. You pay for one build and keep both apps in step.
Updates after launch
Apple and Google update their requirements every year. We keep your app current during support and flag changes before they block your next release.
Your accounts, your code
Your developer accounts, code, and signing keys stay in your name. Moving to another team later doesn't mean republishing from scratch.
Honest about native or not
If your app needs native code for heavy graphics or special hardware, we say so up front. You won't pay for a shared codebase that fights the device.

Good fit
Startups launching a first app
You've validated the idea and need a store-ready app on both platforms without funding two separate teams.
Businesses adding a customer app
Your customers keep asking for an app to book, order, or track, and it has to connect to systems you already run.
Teams that work away from a desk
Your field staff need an app for jobs, checklists, and photos that keeps working when the signal drops.
Owners of an app that keeps crashing
Your app collects one-star reviews for crashes, and you need a team that can fix it or rebuild it properly.
Buyers comparing app developers
You're comparing each mobile application development company on your list and want real device testing, store experience, and a fixed price.
Not a fit
First version to test
You need a first version to test demand before a full app. Our MVP Development Services page begins with a prototype and one core journey.
Laptop-first product
Your product is used mostly on laptops, like a dashboard or subscription tool. Our SaaS Development Services page covers web platforms.
3D game
You're building a 3D game or a graphics-heavy app. A game studio with engine experience will serve you better than an app team.
Mobile-friendly site is enough
Your budget is under $1,300, or a mobile-friendly website would do the job. We'll say so before we quote, because a responsive site costs far less.

Mobile app development cost at DeveloperLook starts at $1,300 for your tested prototype and a fixed build quote. A store-ready app for both platforms starts at $4,700, and a full app with payments, roles, and offline use starts at $9,200. Store developer fees are billed to you directly, and your free discovery call fixes the scope.
A store-ready app usually takes 8 to 12 weeks from the first call. A full app with payments and offline use takes 12 to 18 weeks. Apple says 90% of submissions are reviewed in under 24 hours. New Google Play personal accounts need a 14-day closed test first, so we start it early.
Building your app means designing the screens, writing the app code, connecting a backend, and getting it through App Store and Google Play review. Most business apps now use a cross-platform framework like React Native or Flutter, so one codebase serves both stores. Your work continues after launch, because each yearly OS release needs testing and store rules change too.
Mobile apps are developed in five stages: discovery, design, build, store review, and updates after launch. Designers turn user flows into a clickable prototype you can try on your phone. Developers then work in short sprints and send test builds to your device. Before release, the team prepares your listings and privacy details, then fixes whatever your first users hit.
Pick a team with released apps you can download, testing on real devices, and experience getting through store review. A good partner also puts scope, price, and dates in writing and sets up developer accounts in your name. Ask how they handle OS updates after launch, and who pays for them, before you sign anything.
Write down your must-have features and the phones your users carry, then interview teams with apps live in both stores. Ask each one to walk you through a past release, including how they handled a store rejection. Freelancers can suit a small app, while a team covers design, backend, and testing together. Either way, keep the code in your name.
Build an app when your customers come back often, need phone features, or must work offline; otherwise a fast mobile website may be enough. Apps suit bookings, orders, loyalty, and field work where push alerts or the camera help your users. A one-time visit, like reading a menu, rarely justifies store upkeep. We'll tell you before we quote if a responsive site fits you better.
Compare the proposals you receive on scope detail, not just price: each should list your screens, features, platforms, and what happens at store review. Check that real-phone testing, account deletion, and privacy labels are included, because missing items come back to you as change orders. A fixed price with dated milestones beats an open hourly estimate. Also confirm that you own the code and signing keys.
Going native means writing separate apps in Swift for iOS and Kotlin for Android, each with its platform's own tools. It gives you the fullest access to device features and the best graphics performance. Most business apps do well cross-platform with React Native or Flutter instead, sharing one codebase for iOS and Android. We recommend native only when your feature list needs it.
Yes, if your app lets people create accounts. Apple's App Review Guidelines require account deletion inside the app, and Google Play requires an in-app path plus a web link for deletion requests. We build both into the sign-up flow, so review doesn't stall on it.
