iOS and Android app development, from first sketch to the app stores
GOOD DEV builds mobile apps for iOS and Android: loyalty and membership apps, booking apps, shopping apps and tools for field teams. We help you choose between native and cross-platform, then design, build, connect the backend and take care of App Store and Google Play submission, all with one team.
- iOS & Android, one team
- Store submission handled
- Weekly builds to test
- You own 100% of the code
What we build
Membership & loyalty apps
Digital member cards, coupons, points and promotions via push notifications to bring customers back.
Booking & appointment apps
Book a service, pick a branch and time slot, pay in advance and get reminders, so fewer customers miss appointments.
Shopping & food ordering apps
Product catalogue, cart, QR or card payments and real-time order tracking.
Field & staff apps
GPS check-in, photo reports, QR/barcode scanning and data capture that keeps working where the signal is weak.
Companion apps for existing systems
Extend your website, ERP or CRM to mobile so customers and staff work from the same data.
What you get
- UX/UI design following iOS and Android guidelines, with a clickable prototype
- App development plus the API and admin panel to manage your data
- Push notifications and deep links
- Payment integration and sign-in with LINE, Google or Apple as needed
- Testing on real devices, with TestFlight / internal testing builds for your team
- Store listing preparation and submission until approved on the App Store and Google Play
- Crash reporting and analytics to see how the app is really used
- Full source code, account handover and a post-launch warranty
How it works
- 1
Discovery & platform choice
We agree on goals, users and the features that matter for version one, recommend native or cross-platform and send a free estimate.
- 2
User flows & screen design
We design the flows and screens in Figma as a prototype you can tap through on your own phone, and refine it before development.
- 3
App and backend in sprints
We build feature by feature and send you a new build to install every week, so you see real progress early.
- 4
Testing & store submission
We test across devices and OS versions, run user acceptance testing, then prepare and submit the app for Apple and Google review.
- 5
Launch & iterate
After launch we monitor crashes and usage, fix issues under warranty and plan the next release with you.
What affects the price
App budgets vary widely with scope, so we give you a free estimate after understanding your needs, broken down feature by feature. The main cost drivers are:
Features and complexity
An app that mainly displays information is much lighter than one with accounts, bookings, payments, chat or live maps.
Platforms and approach
iOS or Android only, both from one cross-platform codebase, or separate native apps for each.
Backend and integrations
Whether we build a new API and admin panel or connect to existing systems such as ERP, POS, payment gateways or LINE OA.
Offline mode and device features
Storing data locally and syncing later, or using the camera, GPS, Bluetooth or scanners, adds development and testing.
Post-launch care
Apple and Google ship new OS versions every year, so apps need regular updates. Monthly support plans are optional and sized to your needs.

Most business apps (membership, booking, shopping) work very well with a cross-platform framework such as Flutter or React Native: one codebase for iOS and Android, so less time and budget. Native Swift or Kotlin makes sense when the app relies heavily on device hardware or needs exceptional performance. We recommend based on your actual feature list.
Typically around 2–6 months, depending on the number of features and how much backend we need to build. We usually suggest launching a focused first version with the core features, then adding more based on real user feedback. That gets you to market sooner.
Yes. We prepare screenshots, descriptions and the privacy policy, and handle review until the app is approved. We recommend opening the Apple Developer and Google Play Console accounts under your own company so the app is fully yours, and we’ll guide you through it.
Almost every app does: to store user data, manage products, send notifications and view reports. We can build the API and web admin panel in the same project, or connect to systems you already use through our API integration service.
Your goals, who the users are and a rough feature list (it doesn’t need to be complete), a few apps you like, and your logo or brand guidelines. If you have no screens yet, our UX/UI design team can map the flows and design everything from scratch.
