— Process

How we work

1. 01

   Discovery

   Week 1 — feature spec, target users, monetization model. The output is a fixed scope and a fixed price.

2. 02

   Design & architecture

   Week 2 — wireframes, brand integration, backend schema. Backend setup starts in parallel.

3. 03

   Development

   Weeks 2-4 — KMM build with weekly demos. You see and test the app every seven days.

4. 04

   Launch & store submission

   Week 4-5 — TestFlight + Internal Testing on Google Play, then production submission to both stores.

— Questions

Things people ask

• Why Kotlin Multiplatform and not React Native or FlutterFlow?

  KMM gives native UI on both iOS and Android from a single Kotlin codebase. React Native ships JavaScript through a bridge — fine, but laggier on complex UIs. FlutterFlow is a no-code builder where you pay monthly to keep your app alive and don't own the source. KMM gives you ownership, performance, and the same architecture used by Cash App and Square.

• How long does an app actually take?

  Trainer/course apps are 3-4 weeks. Booking apps 4-5 weeks. Custom 5-6 weeks. The clock starts after Discovery (week 1), once we have a fixed scope. We demo weekly, so you always know where we are.

• What's required from me as a client?

  Brand assets (logo, colors), final product / service list, store accounts (Apple Developer + Google Play Console — yours, not ours), and decisions on monetization. Roughly 4-6 hours of your time across the project.

• Will my app be in the App Store and Google Play?

  Yes. We handle screenshots, descriptions, store metadata, review responses, and the first production submission to both stores. You keep ownership of both store accounts.

• Who owns the code?

  You do. Source code lives on a GitHub repo we transfer to your account at handoff. No license restrictions, no platform lock-in. If you fire us tomorrow, another developer can pick the code up immediately.

• What about Apple Developer Account fees?

  $99/year (Apple) + $25 one-time (Google). These are paid by you directly to Apple/Google — they belong on accounts you own. We help you set both up if you don't already have them.

• Can I add features later?

  Absolutely. The whole architecture is built around adding features without rewriting. Most clients ship a v1, gather feedback for 2-3 months, then come back for a v2 update.

• What if Apple rejects my app?

  We handle the back-and-forth with the App Review team and resubmit. Common rejections (subscription wording, privacy declarations, missing screenshots) are anticipated and avoided up front. Resubmission is included in the project.

• Do you handle iOS/Android updates after launch?

  That's what the App Support Plan ($149/month) is for — OS compatibility checks, store policy updates, crash monitoring, dependency upgrades. The first 30 days are free; after that, the plan is required because abandoned apps get pulled from the stores.

• Can the app integrate with my existing website?

  Yes. The Supabase backend can connect to a WordPress, Astro, or Next.js front-end, so customers see the same data on web and mobile. Two-way sync is part of every Booking tier.

• What about user data and privacy?

  Supabase is hosted in the EU (Frankfurt by default, Ireland on request). GDPR-compliant by configuration. We add privacy policy text, App Tracking Transparency prompts, and Data Safety declarations as part of every launch.

• Do you build the backend or use an existing one?

  By default we set up a fresh Supabase project — auth, database, storage, realtime, all configured. If you already have a Supabase / Firebase / custom REST backend, we connect to it.

• Can I see the code before paying full price?

  Yes — projects are split into milestones (Discovery, Design+Architecture, Build, Launch). After each milestone we transfer the corresponding code into your GitHub. You never pay for code you haven't seen.

• What happens if I want to migrate to another developer later?

  Hand off the GitHub repo + Supabase project + store accounts (already yours) and any KMM-experienced developer can take over. The stack is mainstream, the code is documented, and there's nothing proprietary holding you to us.

• How do you handle multilingual apps?

  EN / UK / RU is included as a single language at launch (your choice). Additional languages are an add-on at $295 each — translation memory, locale-aware formatting, and store listings localized.
