Custom iOS and Android app development
Turn your app idea into a working iPhone and Android product.
Start with the smallest useful app.
Store submission support does not guarantee approval.
From $3,500 · final scope and price agreed in writing
Scope, examples & what is included
We design and build focused mobile apps for founders and businesses—from the first usable version through backend, testing, and store submission.
You work directly with Leon, who shipped a live App Store product end to end, including subscriptions and review.
Is this the app problem you have?
- You have an app idea and no technical team
- Customers keep asking whether your business has an app
- You need a first usable product before investing in a larger build
- Your existing prototype still cannot be shipped
- You need the backend, accounts, notifications, or payments—not just screens
What the first release can include
- iPhone and Android from one codebase when that is the right technical choice
- the backend, accounts, notifications, and payments behind the app
- App Store and Google Play submission support, including review responses
- subscriptions and in-app purchases wired to the agreed scope
- agreed project accounts are set up in your name and included source code is handed over; app stores, libraries, and vendors keep their own terms

Curio — live App Store product
A consumer iOS app designed and shipped end to end, with a backend, subscriptions, App Store review, and content in four languages.

App development questions
What happens before you build, and what does an app cost?
We first define the smallest useful release, its users, required screens, accounts, integrations, and store plan. Focused app builds start at $3,500, and you receive a fixed written quote before work begins.
Do I need an app or would a mobile website be enough?
A mobile website is usually the smaller first step when people only need to find, contact, book, or buy from you occasionally. An app becomes useful when customers return often or need accounts, notifications, offline access, or phone features. We'll recommend the smaller option when it fits.
Can you take over an existing prototype or codebase?
Often, but we inspect the code, accounts, backend, and store setup before quoting. If repairing it would cost more than rebuilding the focused first version, we'll explain that before work starts.
Should we start with iPhone, Android, or both?
That depends on your users and the fastest useful first release. When one shared codebase is a sound choice, we can build for both; otherwise we'll explain why starting with one platform reduces risk.
How long does launch take, and can you guarantee store approval?
The build timeline is written into the scope after the first version is defined. Store review happens on Apple or Google's schedule and approval cannot be guaranteed, but submission support and reasonable review responses are included when specified.
Who owns the app, and what happens after launch?
The agreed project accounts and store listing are set up in your name, and the included source code and backend setup notes are handed over. Any maintenance or post-launch support is written separately; app stores, hosting providers, libraries, and other vendors keep their own terms.
