What’s included
The parts the work is made of — and where to read more about related formats.




01
Phone-first flows
Short paths to the main action, designed for one hand and a small screen. We spell this out so the result is usable for an estimate, build or handover without guesswork.

- 03Notifications
- 04Offline and errors
Who it’s for

Real products from the project catalogue, with what was actually built in them.
Tell us the task — we’ll outline scope, timeline and cost
The brief takes a few minutes. We reply with the next step, risks, timeline and a cost range.
How the work goes
Stage 1
Audit and brief
Who the product is for and where it stands today.
- Brief and product goals
- Review of the current product or competitors
- Roles and key scenarios
- First-version scope
Stage 2
UX: flows and prototype
Logic first, visuals second.
- User flow map
- Structure and navigation
- Wireframes
- Clickable prototype
Stage 3
UI: concept and layouts
The visual language and every screen with its states.
- Visual concept
- Key screen layouts
- States and responsive layouts
- UI kit and design system
Stage 4
Handover and support
We stay close while the interface is being built.
- Figma layouts and components
- Walkthrough with developers
- Implementation review
- Development with us — optional
Why TIVONIX
- 01
One owner of the result
The work is led by the TIVONIX founder: responsibility isn’t spread across contractors and decisions are made quickly.
- 02
Design tied to the back end and architecture
Screens are designed together with roles, data, states and APIs, so the interface holds up once development starts.
- 03
Code and access stay with you
Source code, access, environment settings and instructions are handed to the client. The project isn’t locked to us.
- 04
Built in working parts
We show working parts of the system, not pictures: interface, server side, admin panel and integrations.

FAQ
Do you design Telegram Mini Apps?
Yes. We account for Telegram specifics: theme, buttons and navigation inside the messenger. Slotty’s Mini App is an example.
Can you build the app afterwards?
Yes. TIVONIX builds web apps and Telegram Mini Apps; scope is discussed after the design.
Can I order design without development?
Yes. We hand Figma layouts and components to your team — and can build the interface too if needed.
How is the cost formed?
It depends on scope: how many roles, screens and scenarios, which integrations and launch requirements, and what already exists. Scope and price are fixed in writing after reviewing the task — before work starts.
How long does it take?
It depends on scope and on what already exists. We name the timeline after reviewing the task and split the work into stages with intermediate results, so you see progress instead of waiting for the end.
What do you need to get started?
A short description of the product and users, the task, and whatever exists already: designs, code, documents, access. That’s enough for a brief — we reply with the next step, risks, timeline and a cost range.
Which industries do you work with?
SaaS, fintech, e-commerce and internal systems. Launched projects include a booking marketplace, an AI commerce platform, a music fintech platform and a partner dashboard.
Who keeps the code and access?
You do. Source code, access and clear documentation are handed over to the client.
