Athletes train and track readiness in the app; coaches build plans and follow their clients' load in the admin. - Client: KOUTCH s. r. o. - Year: 2025–2026 - Services: Mobile App, Web Development, UI/UX Design, Backend ## Client training – outside the coach's view A personal coach often sees a client once or twice a week. The client does the other sessions alone from a spreadsheet, a PDF or a chat message, and the coach doesn't know whether they were done, with what weights, how hard they felt or whether the client is sleeping well. Bratislava-based KOUTCH s. r. o. wanted to bring all of this into one place. The platform has a mobile app for athletes (iOS and Android, in Slovak, Czech and English), a web admin for coaches and a community forum. We built the app, the admin and the server that connects them, as well as koutch.com, the website that presents the platform to athletes and coaches. The collaboration started in July 2025. We built the first version of the website in autumn 2025, before the app was released. The app was released on the App Store on 27 August 2026. ## Two audiences and two interfaces – signal loss and App Store rules An athlete needs a simple session in hand, a coach needs an overview of dozens of people. The app has to work where the phone loses its network, and the website has to show each group its part of the platform. - **Everyone in their own interface**: The app is only for athletes and community members. A coach who tries to sign in is pointed to the web — plans, clients and tests live in the admin. So koutch.com shows different content to athletes and to coaches. - **No set gets lost**: Basement gyms often have no signal. Set results are stored on the phone and sent once the network is back. - **Sports science without jargon**: The Hooper questionnaire, session-RPE and ACWR are methods used by professional teams and mean nothing to a beginner. The app shows them as a colour and one sentence; the website describes them without formulas. - **No payments in the app**: Apple rejected the app several times under its in-app purchase rule. The client decided that the app would be free for athletes and coaches would pay on the web. So every section of the website links to a store, the admin or the forum. ## Principle The coach plans in the web admin, the athlete trains in the mobile app, both work with the same data, and every section of koutch.com links to the app, the admin or the forum. - **Every set is logged**: The app guides the session and sends results to the server. The coach sees what the client actually did. - **Readiness and load in plain terms**: From the morning questionnaire, RPE and minutes trained the app computes readiness and load and shows them as a colour and a word — for example, that the athlete is ready for a maximal effort. - **One visual language**: The dark theme, typeface and KOUTCH brand colours are the same on the website, in the app and in the admin. ## The coach's training plan – as a calendar in the app In the admin the coach builds session templates, turns them into a plan by weeks and days, and assigns it to a client or a whole group. The athlete sees it in the app as a calendar with today's session and the plan's completion percentage. - Warm-up, main part and cool-down blocks with estimated minutes - Supersets and giant sets labelled A1, A2; drop sets with computed weights - 15 metric types in a set prescription — from kg and reps to RIR, %1RM and heart rate ## The training session – set logging, rest timer and summary Starting a set triggers a countdown; after the set the athlete enters the result on a wheel and the rest timer runs on its own. In a superset the app alternates the exercises, then gives a round rest. At the end the athlete rates the whole session from 1 to 10. The summary shows duration, volume, average RPE and new personal records — 1RM, 3RM, 5RM, max weight or volume — next to the previous value. - Rest can be paused or skipped, and so can a set or exercise - Without signal, sets wait on the phone and the app shows how many are pending - The summary can be sent to the coach or a group in one tap ## Readiness and training load – Hooper questionnaire, session-RPE and ACWR Four questions from the Hooper questionnaire — muscle soreness, fatigue, sleep quality and stress — on a 1–7 scale. The app turns them into a readiness percentage, assigns a band from excellent to low and shows a 7-day trend. The method comes from monitoring elite swimmers (Hooper and Mackinnon, 1995). Every session becomes one number: effort × duration in minutes (session-RPE). That makes a run, a strength session and a match comparable. From the weekly figures the app computes Foster's monotony and strain. ACWR compares the last week's load with the long-term load. Its scientific basis is disputed, so the app never shows it alone: it combines it with readiness into six states and calls the figures preliminary with fewer than 7 days of data. It serves as a warning of a sharp change in load and does not predict injuries. - Optional body weight, HRV, resting heart rate and a note - An alert when readiness is critical two days in a row - Only the athlete and their coach see the data ## 126 diagnostic tests – in ten categories The test catalogue was built with a practising coach as the expert guarantor. The coach records results in the admin, one by one or in bulk for a whole group, and the athlete sees them in the app as a chart with the personal best marked. - Max strength & 1RM: 38 tests - Lower-body power: 18 tests - Linear speed: 15 tests - Mobility: 13 tests - Anthropometry: 10 tests - Endurance: 9 tests - Change of direction: 8 tests - Upper-body power: 6 tests - Sprint F–V profile: 5 tests - Reactive strength: 4 tests Source: KOUTCH diagnostic test catalogue in the database, October 2026 ## Messaging and community – coach chat, posts and events Direct and group conversations with photos, videos and files, replies to a specific message and reactions. A Google Meet link shows up as a card with a join button. The community has posts with voting and comments, and events with capacity and sign-ups. The editors can feature coaches' posts as recommended by KOUTCH. ## Exercise library and glossary – videos, a muscle map and 106 terms An exercise library with video, 11 filters and a body map that colours primary and secondary muscles differently. Coaches don't have to send videos separately. A glossary explains 106 terms in three languages and works without a connection. Plus a coaches' blog where each article opens with a short summary of key takeaways. ## The koutch.com website – content for athletes, coaches and the community The features section starts with why you came: "I am here to train", "I am here to coach" or "I am here to connect". The choice swaps the whole section without a page load — cards, interface previews and copy. The website shows readiness and load as the athlete sees them in the app, without formulas. For coaches it presents a profile in the coach search, a place in the forum and their own articles. - Athletes: find a coach, training plans, readiness, exercise library - Coaches: training builder, visibility, forum, own articles - Community: discussions and local events ## Links into the products – app stores, coach admin and forum The website has no account or contact form of its own. The athlete button in the header and in the pricing section opens a dialog with a choice of the App Store for iPhone and iPad or Google Play for Android. The coach button leads to the admin at admin.koutch.com. The "Forum" link opens the community site community.koutch.com, which can be read without signing in. ## English and Slovak – and a mobile layout of the website The website is in English at koutch.com and in Slovak at koutch.com/sk. The switcher sits in the footer, the chosen language is remembered, and search engines get links to both language versions on every page. On a phone the audience switcher stacks vertically and the menu opens full screen with two buttons — for athletes and for coaches. ## The app on the App Store and Google Play – and koutch.com in two languages KOUTCH has been on the App Store (Slovakia, Czechia, USA) since 27 August 2026 and is also available on Google Play. Athletes get the whole app for free; coaches work in the web admin. Paid plans, sessions and events are ready and switched off for now. The mobile app, the coach admin and the server that connects them work with the same data: what the athlete logs on the phone, the coach sees in the admin. The koutch.com website in English and Slovak presents the platform to both audiences and links them to the app, the admin or the community. ### What we delivered - Mobile app for iOS and Android - Web admin for coaches - koutch.com website in English and Slovak - App and website design in the KOUTCH identity - Readiness and training load monitoring - Diagnostics with 126 tests - Messaging and community - Session logging without signal --- Web version: https://interfase.sk/en/case-studies/koutch/aplikacia llms.txt: https://interfase.sk/llms.txt
