Said by people who worked with us
Young Ukrainian team from Dnipro. They work day and night and deliver strong solutions in a short time. Their determination is inspiring.

Frank Versaevel
Vice President, Volvo Cars
LeetSoft has something that's hard to find: clarity. They know what they're doing, and they know who they're doing it for. I was impressed by their ability to combine real-world market data with practical solutions for the automotive industry — tools that truly add value. They're young professionals with a clear vision and a very concrete approach. Great people. Without a doubt, a team to follow.

José María Galofré Ragel
CEO, Volvo Car España
I've had the chance to work alongside Ivan and the LeetSoft team, and I have to say: these are people who actually care about what they do. They bring real expertise to the automotive software space, and they don't just talk about results — they deliver them. In a world where finding reliable partners is harder than ever, LeetSoft stands out. Good people, strong team, and a company that knows where it's going.

04 — Process
Our fitness app development process
- 01
Discovery
We map the member journey, the business rules around bookings and access, and what "engaged" actually means for this product.
- 02
UX for engagement & gamification
We design the mechanics that keep people coming back: streaks, rewards, leaderboards, and progress, without turning the app into a slot machine.
- 03
Development
React Native for mobile, a Node.js backend, and a database setup (PostgreSQL and Redis) sized for the real load of activity tracking and bookings.
- 04
Integrations
Payments, QR or badge access control, and any third-party booking or CRM systems the club already runs on.
- 05
QA
Testing against real usage patterns: concurrent bookings, leaderboard updates under load, and access sync when a membership changes.
- 06
Launch & support
We stay on to monitor performance, fix issues, and add features as the member base grows.
05 — Frequently asked questions
Frequently asked questions
It depends on scope. A booking and membership app is a smaller build than a gamified app with real-time leaderboards and an in-app economy. We scope cost after discovery, based on the actual feature set.
