Kai, your AI coach, adjusts it every week to your form, your schedule and your watch.\n\nA PLAN BUILT FOR YOUR RACE\n\nPick your race, your goal and your priorities, then tell Kai how many runs a week you can fit in, on which days, and when you do your long run. Kai builds your program week by week up to race day: intervals, easy runs, long runs, hill work for the trail, paces set from your goal on the road.\n\nKAI READS YOUR COURSE\n\nMap, elevation profile, hardest climbs and descents, aid stations: Kai spots what will cost you the most and prepares you for it. Set your target time and get your split at every aid station, with your margin on each cut-off. Race not in the app? Import its GPX.\n\nRUNNING, STRENGTH AND MENTAL IN ONE PLAN\n\n• Runs with clear blocks: warm-up, intervals, recovery, heart rate zones and paces\n• Short strength sessions designed for runners, placed so they don't get in the way of your runs\n• Mobility, cross-training and rest days\n• Mental training in the same week: visualization, breathing, anchor phrases\n• Mental cues in some runs, to put what you've trained into practice\n\nYOUR SESSIONS ON YOUR WATCH\n\nSend a run to your Apple Watch, COROS or Suunto in one tap and follow it block by block on your wrist. Your workouts, sleep and recovery come back to Kai from Apple Health, COROS, Suunto or Polar.\n\nA PLAN THAT ADAPTS EVERY WEEK\n\nShort nights, a busy week, a heatwave on Saturday: Kai reads your watch, listens to what you tell it and rewrites the sessions ahead. After each session, tell it how you felt. Change your rhythm anytime in your training preferences.\n\nPLANNED VS DONE\n\nTime, distance, elevation gain and pace, week after week: see what you planned and what you actually ran.\n\nMENTAL PREPARATION, THE KAIRN DIFFERENCE\n\nYour legs may be ready, but stress, doubt or a start that's too fast can ruin a race. Kairn trains your mind too, with short, practical exercises designed for runners:\n\n• Manage pre-race stress\n• Build your confidence\n• Visualize the key moments of your race\n• Master your start and your pace\n• Stay focused when the effort gets hard\n• Face doubt and the fear of cracking\n• Debrief your race to keep improving\n\nTake the mental profile test, designed with mental performance experts, to find your strengths and what to work on: confidence, focus, stress management, motivation and resilience.\n\nKAI, ALWAYS BY YOUR SIDE\n\nWrite to Kai or send a voice message whenever you need to: a question about a session, a dip in motivation, pre-race nerves. Kai also checks in on its own at key moments and debriefs your runs with you.\n\nAdd your program to Apple Calendar or Google Calendar: every session on its date, updated whenever Kai adjusts your plan.\n\nKairn is free to download, with a free trial. A monthly or yearly Kairn Premium subscription unlocks the whole plan.\n\nKairn does not replace medical advice. Listen to your body: if anything hurts, stop and see a health professional.\n\nTrain your body. Train your mind. Run your best race.\n\nPrivacy policy: https://kairn.co/privacy-policy\nTerms of use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/","facts":{"developer_id":1791948140,"developer_url":null,"first_released":"2025-11-08T08:00:00Z","support_url":"https://kairn.co/","privacy_url":"https://kairn.co/politique-de-protection-des-donnees-personnelles-et-de-la-vie-privee","website_url":null,"app_version":"3.0.1","release_notes":"What's new:\n• Your training plan is now free, for this race and every one after\n• With Premium, Kai adapts it to how you feel, your progress and your week\n• Your latest COROS activities come in as soon as you open the app\n• More reliable sign-in and account creation","rating_current_version":null,"rating_count_current_version":0,"star_counts":[0,0,0,0,0],"genres":["Health & Fitness"],"languages":["BG","HR","CS","DA","NL","EN","ET","FI","FR","DE","EL","HU","IT","LV","LT","NB","PL","PT","RO","SK","SL","ES","SV","UK"],"content_advisories":null,"device_families":["iphone"],"made_for_iphone_duo":false,"chart":null},"freshness":{"apple_read_at":"2026-11-12T22:23:13.109Z","catalog_read_at":"2026-11-08T22:38:12.835Z","reviews_checked_at":null,"summary_written_at":"2026-11-12T22:59:12.803Z","placed_at":"2026-11-08T16:13:12.856Z","scored_at":"2026-11-14T12:42:13.432Z"},"editorial":{"one_liner":"AI running coach for road and trail races that builds training plans, course strategy and mental preparation.","what_is":"Kairn is a Health & Fitness app that builds a training plan around a chosen race, from 10K to ultra-trail, combining running, strength and mental training.
