A native mobile platform for training and clients
The KOUTCH native mobile app brings trainers and clients together — guided training, daily readiness and a community layer instead of paper plans.
KOUTCH s. r. o. is a Bratislava company building a platform that connects trainers and athletes across Slovakia and Central Europe. The goal is to replace informal coaching (messages, spreadsheets, paper) with a single place where an athlete finds a trainer and gets a tailored plan.
The goal was to build a native mobile app from scratch that connects trainers and athletes in one place, guides an athlete through training step by step, and collects daily body-readiness data, supporting monetization through subscriptions and the sale of training plans.
Developing the app, we tackled several key challenges.
- Two very different audiences in one app
An athlete needs a simple, motivating experience; a trainer needs analytical insight and content-management tools — both groups need to feel the app is "theirs."
- Live guided training
Stepping through exercise → video → set → timer → result logging has to stay smooth even on poor gym Wi-Fi, with the ability to pause without losing an in-progress workout.
- Meaningful analytics from simple inputs
Overload risk and ACWR need to be derived from a daily Hooper questionnaire and logged workouts without it feeling like "science for scientists."
- Community and monetization without distraction
The social layer and paid model have to complement the app's core purpose, not overshadow it.
We built a native app in Expo/React Native with a dark, "premium fitness" design and connected it to a Laravel backend. At its core is the training module: plan → workout session → exercise blocks → individual sets logged with weight, reps and duration.
- Guided training as a sequential flow with a rest timer and haptic feedback
- A daily Hooper questionnaire translated into a readiness score and a 7-day trend
- ACWR and other load metrics for overload-risk alerts
- A community layer — posts, blogs, events, a leaderboard and an achievement system
- Direct messaging between trainer and client
- The koutch.com marketplace — finding a trainer by specialization and price, selling ready-made plans
Concept and UX for two audiences
We defined separate flows for the athlete and the trainer so both would feel the app is "theirs."
UI design
We designed a dark, premium fitness look with glass cards and a single strong accent color.
Mobile app and backend development
We implemented the native app in Expo/React Native and a Laravel backend with a Filament admin panel for trainers.
Launch and distribution
We deployed the app via EAS Build to the App Store and Google Play, bilingually (SK/EN, with Czech prepared).
KOUTCH replaces fragmented communication over WhatsApp, Excel and paper with a single app, where a trainer tracks clients' readiness and load and an athlete trains through a step-by-step guided workout. Among its first users is a professional athlete.
