Mobile Apps

Mobile apps,
from idea to the store

WoodstoneStudio is a remote-first digital technology studio working with clients worldwide. We build iOS and Android apps from a single Flutter codebase and handle everything from design to App Store and Google Play release. Our own apps are live in both stores — we know the process first-hand.

What we
do

An app is not just written; it passes store review, reaches users and stays alive. We run the whole journey under one roof.

iOS & Android apps

One Flutter codebase, both platforms — one team, one budget, two stores.

MVP & first release

We turn your idea into a testable first version fast, then grow it with real user feedback.

AI-powered apps

Chat assistants, image recognition, content generation — we integrate AI features into your app.

Backend & infrastructure

User accounts, database, push notifications and payments (subscriptions, in-app purchases).

Store publishing

App Store and Google Play submission, review process, store listings and screenshots — with you until approval.

Updates & maintenance

Version updates, bug fixes and new features after launch.

Mobile app guide

Mobile app or mobile-friendly website?

Not every business needs an app. If customers visit you occasionally, a fast mobile-friendly website is often enough. An app makes sense when users come back regularly: tracking, habits, loyalty, notifications, or when you need device features such as the camera, location or health data.

We answer this question honestly with you in the consultation. If what you need is a website, we won't try to sell you an app.

Native or cross-platform?

Writing separate native apps for iOS and Android means two codebases, two teams and almost twice the budget. With cross-platform technology such as Flutter, one codebase ships to both stores.

For most business apps, content and tracking apps and MVPs, cross-platform is the right choice: faster to build, easier to update, and users can't tell the difference. We recommend native development only in rare cases that need very heavy graphics or platform-specific hardware.

From idea to app store: the development process

An app project usually goes through these stages:

  • Discovery: the target user, the problem being solved and the must-have features of the first version are defined.
  • Design: screen flows and the interface are designed and approved through a clickable prototype.
  • Development: the app and its backend are built together, with regular test builds shared with you.
  • Testing: tested across devices and screen sizes using TestFlight and Google Play internal testing.
  • Store launch: store copy, screenshots, privacy policy and the review process are handled.
  • After launch: the app grows through user feedback, bug fixes and new features.

Why starting with an MVP is smart

An MVP (minimum viable product) is the first version that contains the core of your idea and can be tested with real users. Shipping the most valuable part first instead of building every feature upfront protects your budget and shows which features people actually want.

We build our own apps the same way: first the smallest version that works, then growth driven by user data.

App Store and Google Play publishing: the invisible part of the job

The work isn't done when the code is. Apple's and Google's review rules, privacy disclosures, account-deletion requirements, subscription rules and store assets all take real preparation. Apple's review is especially strict, and a rejected submission can cost weeks.

We have published our own apps on the App Store and Google Play, and learned rejection reasons, fixes and store policies first-hand. We bring that experience straight into your project.

AI-powered apps

AI is now an ordinary part of mobile apps: chat assistants, photo analysis, personalised recommendations, text and image generation. JoVVo, for example, has an AI coach that estimates calories and macros from a meal photo and builds personal training programs.

We integrate AI features through a secure server layer, so API keys never live inside the app and costs stay under control.

Monetisation: subscriptions, in-app purchases, ads

How your app will make money should be planned from the start. The most common models:

  • Subscriptions: monthly or yearly premium membership, usually with a free trial.
  • In-app purchases: one-off feature or content sales.
  • Ads: revenue from free apps through networks such as AdMob.
  • Hybrid: ads in the free tier, an ad-free premium experience.

After launch: maintenance, updates and growth

iOS and Android release new versions every year and the stores keep adding rules. Apps that aren't kept up to date start to break or lose visibility in the store. After launch we keep working with you on version updates, bug fixes, performance monitoring and new features.

Why WoodstoneStudio?

We don't only build client apps; we design, build, publish and grow our own. We have been through every stage an app goes through, from idea to the store and beyond, with our own products.

In a free consultation we listen to your idea and put together a realistic MVP scope and a written cost estimate.

Frequently asked
questions

How long does a mobile app take?

A simple MVP takes 4–6 weeks, a mid-sized app 2–3 months. We give a clear timeline at the consultation.

Will the app run on both iOS and Android?

Yes. We build both platforms from a single Flutter codebase, which is far more economical than developing them separately.

Do you handle App Store and Google Play publishing?

Yes. We manage submission, store listings, screenshots and the review process. We publish our own apps, so we know it well.

Can AI be added to the app?

Yes. We integrate features like chat assistants, image analysis and personalised content.

I only have an idea — is that enough?

Yes. Many projects start with just an idea; we define the scope together and bring it to life with an MVP.

Do you provide support after launch?

Yes. We continue with a maintenance agreement for OS updates, bug fixes and new features.
