Want to launch it? After your app or game is built and tested, we can prepare it for the Apple App Store or Google Play. You create and pay for your own developer account; we give you the official links and guide you through the rest. Store approval time is separate and depends on Apple or Google.
No technical brief needed
Just say what you want
We build your app or game while you wait. Start with three simple keywords. We turn the idea into a clear plan, build it and test that it works. You receive the expected delivery time before we start.
Start small, grow later. The starting price covers a simple first version. Extra screens, accounts, payments, online data, advanced features or store launch are quoted separately before we build them.
Describe your idea
Write it like you would explain it to a friend.
What this could become

A friendly game with a start button, short questions, multiple-choice answers and a final score.
- Simple screen
- Clear rules
- Works on phone and laptop
- Tested before delivery
01 / The deliverable
What you get
Not a wall of warnings. A report that tells you what matters and what to do next. Every finding has four parts.
01
What goes wrong
The bug and what it means for the person using your app. Plain English, not a jargon puzzle.
02
The proof
The file, the line number, and the evidence. A finding you or your developer can check.
03
How bad it is
A clear priority. Know the difference between lost money, lost data, and an awkward screen.
04
What repairing costs
An estimate in hours and dollars. You see the likely cost before deciding who fixes it.
02 / Inside the report
Sample finding
This is the level of detail to expect. A specific problem, not “your code could be better.”
HIGH PRIORITYCHECKOUT / PAYMENT ORDER
“The buy button charges the card before it checks stock. If an item has sold out, the customer can still be charged, even though the order cannot be fulfilled.”
03 / No complicated process
How it works
You send the code. I do the review. You decide what happens next.
-
01 / SEND
Send me a link
Share your repository or a downloadable ZIP. Tell me what you built and what worries you. I confirm the scope with you.
-
02 / FREE SAMPLE
Get your first findings for free
I review your code and send back up to 3 findings for free, if I identify them: the file, the problem, and how serious it is. No payment. No obligation.
-
03 / YOUR CALL
Pay only for the report you order
Want the complete report, or the repairs? You get a fixed price first and pay only after you approve it. Take the report elsewhere if you prefer.
04 / A second pair of eyes
Who it's for
However the code was written, you need to know where it stands.
You built it with AI
The demo works. Before real users and payments arrive, you want to know what the happy path is hiding.
You hired someone
The project has been delivered. You want an independent look at the code before signing off.
You run a small studio
You're about to hand over a project. Get a fresh review before your client's users put it to the test.
05 / The reviewer
Who reviews your code?
One developer. No agency, no queue.
Independent developer
I'm the developer behind NaturalDub Studio. I build and ship my own web apps, tools and automations, and I review other people's code the same way I want mine reviewed: read it properly, prove every finding, and keep the advice practical.
That also means I tell you when a project is outside what I can review well, instead of taking the job anyway.
AI-assisted, checked before it goes out
Every review is AI-assisted. Your code is scanned with modern AI tooling and static analysis, and the report is drafted and then checked in a second pass before it goes out. That is what makes a review fast and affordable.
It also means this is not a manual, line-by-line human audit — and it is not a full security audit.
The straight answer
No invented experience, no certificates and no client logos — you'll see client reviews here once there are some to show. What you get instead is a straight answer about what I can and can't review for your project.
06 / The scope
What I review — and what I don't.
So you know exactly what you're buying before you pay.
Languages and frameworks
- JavaScript and TypeScript — React, Vue, Svelte, Next.js, Node, Express
- Python — Django, Flask, FastAPI, scripts and data code
- PHP — Laravel, WordPress plugins and themes
- HTML, CSS and front-end accessibility basics
- SQL — queries, schema and injection risks
- Java/Kotlin (Android), Swift (iOS), C#/.NET, Go, Rust
Not on the list? Ask first — I'll tell you honestly whether I can review your stack well.
How the review is done
I read your code and analyse it with modern AI tooling and static analysis. Your app is not run or tested in a live environment as part of a standard review.
That means I can find logic bugs, security risks and maintainability problems by reading your code — but I cannot confirm runtime behaviour, problems that only appear under real load, or anything specific to your own servers. Runtime testing is possible only if we agree on it separately and you provide a safe test environment.
Prices are based on lines of code: non-blank lines in your source files. The Quick check covers up to 2,500 lines and the Deep check up to 15,000. Excluded from the count and from the review: dependencies and vendored code (node_modules, vendor), build output and generated files (dist, build, minified bundles), lock files, and images or other binary assets. One re-check of the fixes is included with both checks; further rounds are billed at the hourly rate.
Outside the review
- No full penetration test or complete security audit
- No guarantee that every bug will be found
- No compliance or certification sign-off (GDPR, PCI, ISO, SOC 2)
- No load or performance testing on your production systems
- No legal or contractual advice
A code review reduces risk. It never removes it.
07 / Your code and your data
How your code is handled.
What to send, what never to send, and what happens afterwards.
How to send your code
Send a link to a public repository (GitHub, GitLab, Bitbucket) or a ZIP archive. For a private repository, say so first and I'll tell you what I need — usually a temporary read-only invitation, or a read-only key that you remove again afterwards.
Never send passwords or API keys. I don't need them and I won't ask for them. If your code only runs with live secrets, describe them instead.
What happens to your code
Your code is used for one thing: producing your review. Files are opened only for that review, and I don't publish, resell or reuse your code. Access to a private repository is removed once the review is finished.
The AI-assisted analysis runs through hosted AI models (the Nous Research inference API) together with standard static-analysis tooling. Parts of your code are sent to those services in order to be analysed.
What I can't promise
I won't make privacy promises I can't verify. I can't promise your code is never seen by a third-party model provider, and I can't promise it is excluded from their retention or training policies — those are the provider's rules, not mine.
If your code is under an NDA or strict internal rules, tell me before you send anything and we'll agree on what's acceptable — or I'll say no.
08 / Know the cost first
Fixed price. No subscription.
Choose the review that fits your codebase. Repairs are separate and always optional.
Founding-client offer
$149 for the Quick check — for the first two clients. Normally $299. One-off, no subscription, and the free sample is still free. I ask one thing in return: honest feedback after delivery, so the clients after you know what to expect.
Free sample
Send me a link and I'll send back up to 3 findings for free, if I identify them. No payment, no obligation, and you keep the findings whatever you decide. You pay only if you order the Quick check, the Deep check or the repairs.

Paying online

Payment links come from our payment provider. We never ask for card details by email, and we never send account numbers.
What exactly do I get?
A plain-English report. Each finding explains what goes wrong, the file and line number, how serious it is, and an estimate of the hours and cost to repair it.
Do I pay for the sample?
No. Up to 3 findings are free, each with the file, the problem and how serious it is — if I identify them. The Quick check, the Deep check and repairs are separate and fixed-price; you approve the price before I start. The sample is deliberately small: it shows how I work, it isn't the full review.
How do I send you my code?
Send a link to your GitHub or GitLab repository, or a downloadable ZIP. If the code is private, send your request first and I will explain how to give me access. Do not send passwords or API keys.
How quickly will I get the report?
The Quick check report arrives within 48 hours; the Deep check report within 5 business days. I confirm the scope and start time with you before I begin.
What if you find nothing serious?
I say so. Your report explains what I checked and any smaller issues I found. I will not invent problems to sell repairs. A code review is not a guarantee that an app has no bugs.
Is the review done by hand or by AI?
The analysis is AI-assisted. Your code is scanned with modern tooling, which is faster and more thorough than reading every line by hand, and every report is checked before it is sent to you. Nothing is ever sent to you automatically.
Can you repair the issues too?
Yes. After the report, I can make repairs at $120 per hour. I estimate the work first and only start with your agreement. You can also take the report to another developer.
10 / Let's look under the hood
Send me your code.
Tell me what you built and where you're unsure. I'll look at the scope and tell you honestly whether I can help. Send a link and get up to 3 findings for free, if I identify them. I'll reply with what I can review, what it costs, and when you'll have it. Looking for text rewriting instead? That lives on its own page.
