Product judgment
Cut broad ideas into focused user problems and testable app flows.
AI-assisted mobile product lab
Build the next useful mobile product with AI.
Focused mobile apps and AI-assisted prototypes.
AI-assisted builds
Mobile MVPs
Launch-ready basics
FilinLab is a compact product lab for testing mobile app ideas in wellbeing, nutrition, learning, and self-improvement.
The goal is not to ship every idea. The goal is to use AI-assisted workflows to find the few apps worth building properly.
Build with FilinLab
A small lab for serious mobile product ideas.
Inspired by the way modern product companies combine capital, platform, talent, and speed, FilinLab keeps the same logic compact: one developer, AI leverage, mobile product experience, and a clear path from idea to launch basics.
AI momentum
Use Codex and Claude Code to move faster without losing maintainability.
Launch discipline
Prepare support, privacy, legal pages, and store basics early.
AI product loop
Research, build, ship, learn - with AI speeding up the loop.
AI helps compress the distance between idea and working prototype, but product judgment still decides what should exist, what should be simplified, and what should be released.
Signal
Find a real user pain and the smallest angle worth testing.
Prototype
Use Codex and Claude Code to move from product thinking to working flows.
Launch basics
Prepare support, privacy, store materials, and the release path early.
Iteration
Keep the evidence, remove the noise, and improve the next version.
Public support contact
Email and phone contact are available for app users, company questions, and privacy requests.
Privacy-first website
The current site does not use contact forms, analytics, advertising pixels, or tracking cookies.
Mobile app development
FilinLab maintains public app, support, privacy, and legal information as products move toward release.
Values
The values behind the build
The site can look polished, but the work still has to be practical: move fast, stay useful, listen to evidence, and launch responsibly.
Move fast with focus
Speed matters only when it moves a clear user problem closer to a testable product.
Build, then learn
Ideas become real through prototypes, store preparation, user feedback, and careful iteration.
Care before scale
Support, privacy, and calm UX are part of the product before growth, marketing, or bigger ambitions.
Work
How the lab turns ideas into apps
Product direction
Narrowing broad directions into focused app ideas with a clear user problem, simple scope, and a reason to exist.
AI-coded prototypes
Using Codex and Claude Code to move faster from design decisions into working mobile product iterations.
Store-ready foundations
Preparing support, privacy information, store materials, and the practical basics Apple and Google expect.
Research pipeline
Product directions under validation
Current directions where AI, mobile UX, and everyday self-improvement can create something sharper than generic tracking apps.
Adaptive mental reset
Short, context-aware sessions for people who need a reset but do not connect with long generic meditation audio.
Nutrition intelligence
A lighter calorie and food-pattern assistant that reduces manual logging and turns daily meals into useful signals.
Practice loops for growth
Small, repeatable lessons for self-improvement skills such as focus, speed reading, training routines, and daily practice.
About
Built by a developer who thinks in products
My name is Illia S. I am from Ukraine, and FilinLab is where I am turning my mobile product experience into independent apps.
My first serious mobile app experience came from working with Ultiself, a company behind a habit tracker app. That work taught me how apps move from product idea to store listing, user feedback, release preparation, and promotion.
Today I use new AI coding tools, including Codex and Claude Code, to design, build, and iterate on mobile applications more quickly while keeping the product focused and maintainable.
