What You'll Receive
Full Description
You have an app idea. What you need is a technical partner who actually listens, scopes the work properly, and builds exactly what your business requires — without surprises on cost or timeline.
That is precisely what Zinn Digital delivers. With 10 years of app development experience, this studio has worked across FinTech, enterprise software, and consumer apps, building products that have reached millions of users and supported significant investment rounds. Whether you need an AI-powered chatbot, a cross-platform mobile app for iOS and Android, or a full web application with integrated intelligence, the process is built around your goals.
**What is included across all packages:**
Every engagement starts with a 60-minute Discovery Call — a structured session where your requirements, constraints, and goals are discussed in full detail and the project scope is set. You leave with clarity on what will be built, how long it will take, and what it will cost. No vague promises.
**What Zinn Digital builds:**
— AI chatbots powered by OpenAI's latest technology, supporting both voice and text interaction
— Cross-platform mobile apps using Flutter or React Native (one codebase, two apps — iOS and Android)
— Native iOS apps in Swift or Objective-C
— Native Android apps in Kotlin or Java
— Web applications with AI feature integration
— Custom AI training, ChatGPT integration, API connections, and data visualisation
**How the process works:**
The engagement begins with a Discovery Workshop to uncover your needs and identify potential issues early. Scoping follows — producing a clear roadmap with timeline and costs. Development is then carried out with weekly progress updates and a single point of contact throughout. Rigorous testing precedes every release.
**Who this is for:**
Non-technical founders who want a reliable studio partner. Businesses that need AI features added to an existing product. Teams that have struggled with vague agencies and want predictable delivery.
**Why Zinn Digital:**
Transparent communication, predictable scope, and a decade of hands-on delivery across complex, real-world products. The studio follows a structured methodology so your project stays on track from first call to final release.
Start with the Discovery tier to scope your project properly — then move to the Boost or Premium build when you are ready to go.

Frequently Asked Questions
You will receive a message in the order chat within one business day to confirm your details and schedule the 60-minute Discovery Call. Please have your project brief, goals, budget range, and timeline in mind before the call — this helps us make the session as productive as possible.
Yes. Where the project uses Flutter or React Native, a single shared codebase runs natively on both iOS and Android. This means you get both platform apps without doubling the development cost or timeline.
All chatbots are built using OpenAI's latest technology, supporting interaction via both voice and text. Integration with ChatGPT and custom API connections can also be included depending on your requirements.
The project scope is agreed in writing before development begins, clearly defining what the finished product should do. Any small adjustment that falls within the agreed scope can be requested as a revision within two weeks of release. The number of revisions depends on the package selected.
It helps to have a clear description of your business, the problem your app solves, your target users, any existing design or technical references, your approximate budget, and your desired launch timeline. You do not need any technical knowledge — that is what the call is for.
You receive weekly progress updates throughout the development phase, delivered via the order chat. You have a single point of contact at all times, so there is no confusion about who to speak to.
Post-launch app support, maintenance, and updates are part of the services offered. These can be discussed and scoped during or after the initial Discovery engagement.
The Discovery Call is also used to assess alignment. If your project requirements, timeline, and goals are a strong match for what the studio delivers, the engagement moves forward. If not, honest guidance is still provided.
