OneFit
About the project
OneFit is a personal online fitness coaching platform by Stanislav Kravchenko — a Ukrainian gymnast, Men's Physique Competitor, and trainer with 12 years of client transformations — offering starter programs and fully personalized training plans with virtual assessments, weekly check-ins, and 24/7 coach support.
Project Overview
The platform delivers two distinct training experiences on one unified product: affordable starter programs for self-guided fat loss and muscle gain, and fully personalized coaching plans built around each client's goals, lifestyle, and location — with ongoing support at every step.
Project Goal
The goal of the project was to bring the quality of elite personal training online and make it accessible at scale. A key focus was placed on reducing the barrier to commitment through a 7-day free trial, flexible pause-and-cancel subscriptions, and a virtual assessment flow that replaces the in-person gym consultation.
Solution
We built a dual-track fitness coaching platform featuring a starter program marketplace (at-home and gym options), a personalized plan flow with virtual fitness assessments, a subscription system with Silver, Gold, and Platinum tiers, 24/7 in-app coach messaging, weekly check-ins, and a client-facing progress tracking experience — all wrapped in a brand backed by major media features.
Key Challenges
Professional personal training is expensive and geographically limited to local gyms
Generic fitness apps deliver one-size-fits-all programs with no real accountability or adaptation
High drop-off when users must commit financially before knowing if the coaching approach works for them
Clients need ongoing motivation and plan adjustments — not just a static workout PDF
Key Features
Starter Programs ($45) — A comprehensive 4–6 week fat loss and muscle gain program for beginners and advanced users, available for home or gym — one-time fee, no commitment.
Personalized Plan ($190) — A fully customized coaching plan built after a free virtual fitness assessment, with ongoing online coaching tailored to your progress, lifestyle, and location.
7-Day Free Trial — Every subscription tier includes a risk-free 7-day trial so clients can experience real coaching before committing — with pause or cancel at any time.
Support 24/7 — Ongoing email and in-app support from certified trainers, weekly check-ins, and program updates continuously adjusted to your results and goals.
