Custom mobile apps, built by one developer, not an agency

What "custom" means for a mobile build

Every app is built with React Native or Flutter by default, so one codebase covers iPhone, Android, and often the web too — a bug fix or a new feature ships everywhere at once, not three separate times. That's what makes a custom mobile app developer working alone competitive on both price and speed against a larger agency: no separate iOS and Android teams to coordinate, no duplicated work.

Startup application development, scoped to a real budget

Fixed scope in writing before anything starts, a working preview link from week one, and a flat $50/hr rate with no agency markup. If the budget is the fixed constraint, the MVP scope calculator works backwards from a number to what actually fits in it, rather than pricing a wishlist and cutting later — see MVP mobile app development for what that looks like end to end.

What it costs

A simple app (one main feature, one core screen flow) usually runs $2,000–$4,000 over 2–3 weeks. A typical full app with a few real features runs $4,000–$8,000 over 4–6 weeks. A complex app — a marketplace or a social app — starts around $7,500 and can run 2 months or more. Run the calculator against your actual feature list for a real number.

Store submission included

Submitting to the Apple App Store and Google Play — screenshots, listing copy, the review process — is included in every full build, and available as an add-on for smaller MVP projects.

If AI is part of the app

A growing share of mobile builds now include some form of AI — a chat assistant, a recommendation feature, an agent connected to a backend. See AI agent development for what that specific piece costs and includes; it's scoped and priced the same way, fixed and in writing before work starts.

Talk to the person building it

No handoff between a sales call and a different delivery team — the person who scopes the project is the person who writes the code. See who's behind Tunovix, or start with a free scoping call.
