Kyiv · mobile & web apps
An app is not a launch. It is years of attentive care.
We design, build and publish mobile and web apps — and then we stay: updates, fixes, new store requirements, and reports you can actually read.

What you receive
Measurable deliverables, not promises
We do not boast figures we cannot show. Instead, every stage ends with a concrete artefact you can check yourself.
Screen & flow map
Each screen has a purpose, its states (empty, error, loading) and an acceptance criterion.
Interactive prototype
A clickable model of the core journeys before development starts — so mistakes cost minutes, not sprints.
Builds with a changelog
Every test build comes with a plain-language note: what changed and what to check.
Store submission pack
Listing copy, screenshots, privacy policy, data-safety forms, age ratings — assembled and agreed.
Monthly care report
What was updated, which dependencies aged, which crashes were fixed, what we suggest next month.
Our position
A partner who stays after release
Most app problems do not appear on launch day but six months later — when the OS, the store rules or the team changes.
So we build for maintainability: documentation, predictable architecture, automated build checks. And if we provide the care, you get a clear rhythm of work and one address for every question.
How care is organised →Quality criteria
What we check before every release
Accessibility
Text contrast ≥ 4.5:1, screen-reader labels, font scaling to 200% without losing content.
Speed
First meaningful screen without needless blocking; build size and request counts tracked in the log.
Stability
Offline, slow network and interruptions (calls, backgrounding) tested on real devices.
Data
The store data disclosure matches what the app actually does.
Language
Ukrainian and English copy proofread; no truncated strings or machine phrasing.
Recovery
A rollback plan exists, plus clear instructions for reporting a problem.
