  • html-prototype

    Prototype your idea

    A clickable HTML prototype in hours, a few versions side by side, with real content and checked on a phone.

    Download SKILL.md
  • app-audit-report

    Audit an app

    An end-to-end audit as one HTML report: a score per area, findings by severity with evidence, and a phased fix plan.

    Download SKILL.md
  • flutter-release

    Prepare a store release

    A Flutter build to TestFlight and Google Play: version bump, flavors, store metadata, review notes and a demo account.

Three more skills, and how to install them
  • security-audit: A whole-project security audit: secrets in the repo and its history, auth on every route, input validation, dependencies, headers and mobile storage, with fixes in priority order. Download (opens in a new tab)
  • flutter-feature: Scaffolds a Flutter feature in Clean Architecture: entity, repository, a Cubit with its state, DI and a page on theme tokens and ARB strings. Download (opens in a new tab)
  • review-gate: A read-only review before a merge or a production push: regressions and backward-compatibility breaks first, then security, clean code and missing tests, with a clear verdict. Download (opens in a new tab)

Install a skill: put it in .claude/skills/<skill-name>/SKILL.md in your project. Claude Code finds it on its own. Read a skill before you install it: it contains instructions your agent will follow.

Is your app ready?

Eight yes-or-no questions, a score and the three fixes to make first. Answers stay in your browser.

Start the self-check
AccessIs row-level security (or equivalent access rules) on for every table, with policies you have tested?
AccessDoes the server check that the signed-in user owns every record they read or change?
DataAre automatic backups on, and have you restored one at least once?
SecretsAre secret keys (service role, payments, AI providers) kept out of the app and the web page?
PaymentsIs paid access granted only after the server checks the store receipt or the webhook?
QualityDo automated tests cover sign-in, payments and your core flow, and run on every change?
ObservabilityDo you get crash and error reports from production?
StoreCan a store reviewer sign in and reach every feature (demo account, review notes, no placeholder content)?

"Not sure" counts as no. A self-check, not an audit.

Answered so far

01Which AI tools and skills do you use?

AI coding agents such as Claude Code, guided by our own SKILL.md files. 40 of those skills are free in the Skills pack above. Codigee experts review every line before it is merged, and automated tests run on every change.

02How long does an MVP take?

About 8 weeks, from the plan to the store release, with a build on your phone every week. See the MVP plan, week by week.

03How long does Apple and Google store review take?

Neither store promises a fixed time, and it changes. We plan the release with a buffer, and we give the reviewer a demo account and review notes, so they can reach every feature. The free store-release skill lists the common pitfalls.

04Can you take over my Lovable, Bolt or Replit app?

Yes. Prototype to Store (from $15k) makes it store-ready, keeping what works, or rebuilds it to last. Not sure what state it is in? Run the free self-check first, or start with an App Audit ($5-8k).

05Flutter or React Native for my app?

We build in Flutter: one codebase for iOS and Android. If you already have a React Native app, we can put a Unity scene inside it, or rewrite it in Flutter (from $20k).

06What does a backend cost to run?

The cloud runs on your own account. It usually costs about $0 a month up to a few hundred thousand users. It depends on the project.

07Do I own the code?

Yes, from day one: your code repository, your cloud account and your App Store and Google Play accounts.

08Can I start with a small budget?

Yes. Start free on this page: the Skills pack, the self-check and Ask us. Paid work starts with Prototype to Plan ($5k, credited 100% to the build) or an App Audit ($5-8k). An MVP starts from $15k. See all prices.

When to call a senior.

Before real users' data or payments go in, or when every fix breaks something else.
