fitbyivana

An autonomous training & nutrition coach.

A coach in your pocket that adapts every week. It plans the training and the food, then adjusts as life actually goes.

How a project flows

Five steps, one direction. Each hands a clear result to the next.

  1. 01

    Discover

    Goals, users, constraints. We agree what to build first, and what to leave out.

  2. 02

    Design

    Flows, interfaces and a working prototype you can react to before code is written.

  3. 03

    Build

    Small, tested increments. Type-checked, with unit and end-to-end tests behind them.

  4. 04

    Ship

    Deployment, App Store submission and the launch checklist, handled.

  5. 05

    Evolve

    Maintenance, iteration and new features — the work that keeps a product running.

How we build

  • Quality gates on every release

    Type checks, unit and end-to-end tests before anything ships.

  • Accessible by default

    WCAG AA contrast, reduced-motion support, large touch targets.

  • One codebase, many brands

    Configuration over forks.

  • Calm software

    Interfaces that respect attention.

A small studio with a single standard.

Tokovic LLC was founded in 2026 by Mihajlo (Mike) Tokovic, a product engineer. It is a Wyoming limited liability company.

Tok means flow, a current. Products should move — from idea to launch, and for the people using them, from tap to result — without friction. Every decision gets the same test: does it help the product move?
