IntervalCoach: AI Training
건강 및 피트니스
무료 · 앱 내 구입
Your workout, rewritten every morning.
IntervalCoach is an AI training coach for cyclists, runners, and triathletes. Every morning it reads 60+ recovery signals — HRV, sleep, sleep debt, training load, subjective wellness — and reshapes today's session before you start.
Not a static plan. Not a generic "easy day / hard day" nudge. A real coach watching your data and rewriting tomorrow's workout based on how you actually slept.
WHAT YOU GET
- Daily adapting workouts that respond to your recovery
- Daily readiness scoring (HRV, sleep, form, training load)
- Five periodization models from peer-reviewed sport science
- Multi-sport: cycling, running, swimming, strength
- Coach+ — a conversational AI coach that knows your data
- Goal event countdown and progress projection
- Activity detail with power zones, AI analysis, and nutrition advice
- Post-workout RPE and feel ratings, plus push notifications
- Weekly summaries and monthly progress reports
- Widgets, App Intents, and Siri shortcuts

If you run with power, the dashboard now has a running-power form card in watts, with a 6-month trend and how far you are from your season best.
Set your own numbers: edit your FTP, threshold pace and threshold heart rate right in the app. They save back to Intervals.icu.
Running power now uses your Running FTP, and you can choose whether it follows your estimated (eFTP) or manual value.
Cadence targets now show on every interval step in a workout, not just the warm-up and cool-down.
Fixed the two most common app freezes, on the Calendar and Analytics screens.
2026.7.30 7월 22일
Race Catalog: browse a catalog of real-world races — gran fondos, marathons and sportives — and add one to your calendar as your goal in a tap. You choose your own A/B/C priority for it. You can also share your own races with the community, and races now cover every sport (ride, run, trail, swim, walk, hike, strength).
Community races now open a details page — tap a race to see its distance, location, event website and description, and pick your A/B/C priority there. You can add notes to any race you create, and when you share a race you can include a link to the official event website.
Fixed a visual glitch when adding a race — the background is now consistent across the Create and Browse tabs instead of flipping.
Fixed the race priority chooser popping up in the wrong place — it now points at the Add-to-calendar button.
2026.7.24 7월 22일
The proposed workout in TrainNow now shows your actual pace and watts next to the training percentages — for example "60% · 150W" on the bike or "76-80% pace · 6:57-7:19/km" on the run.
Counts like "2 warnings" or "3 days left" now use proper plural forms in every language.
The sick/injured banner on the dashboard now shows in your own language.

2026.7.19 7월 16일

2026.7.18 7월 15일
TrainNow: choose whether suggestions fit your plan or today's readiness. On a day your plan left open, switch to "Fit my readiness" to get a session matched to how recovered you are, instead of only an easy option.
Now available in Japanese and Korean (日本語, 한국어). The whole app is translated and follows your device language automatically.
• Redesigned health summary: your dashboard now always shows your most relevant available readings (sleep, HRV, resting heart rate, breathing rate and more), instead of a recovery percentage that just repeated your readiness score.
• Japanese and Korean language support.
• TrainNow can now build a workout around today's readiness, not just your plan.

iPad now uses the full screen. The calendar gets a desktop-style month view with a week summary, goal banner, intensity and RPE on each day, and a side panel for the selected day. The dashboard lays its cards out in two columns, milestones collapse into a compact shelf you can expand, and the sidebar shows every section. Fixed: pages now scroll while your finger is on a chart.

iPad now uses the full screen: a desktop-style month calendar with a week summary, goal banner, and a side panel for the selected day; a two-column dashboard; collapsible milestones; and a complete sidebar. This build also fixes the white bars on either side of iPad pages, makes the whole Recovery/Sleep cards tappable, and opens a workout from the calendar the same way as everywhere else. Plus: pages scroll while your finger is on a chart, and the new calendar labels are translated.
More iPad polish: tapping a day with a single workout opens it directly (and multiple workouts open the side panel to pick); the Add Workout sheet now offers every supported sport and opens at a comfortable size; and the day and workout screens open consistently across the app. Also includes the earlier iPad desktop calendar, two-column dashboard, full sidebar, edge-to-edge pages, tappable Recovery/Sleep cards, and the chart-scroll fix.

More activities now show their own icon: kayaking, canoeing, SUP and rowing, open-water swims, gravel and mountain bike rides, gym sessions, yoga and pilates, and winter sports like skiing, snowboarding and skating.
The weather card now shows which place the forecast is for, so you can check it matches where you'll actually ride or run.
The weather card on your planned workouts now shows in your language. Condition names, labels and details were appearing in English for some languages.
Coach+ now reliably applies calendar changes when you approve more than one at once. Before, approving a batch (like deleting a few workouts and adding a new one in one go) could quietly do nothing.
Coach+ now applies every calendar change when you approve several cards in one go. Deleting or creating a few workouts in the same message and approving each one now updates all of them, not just the first.

Fixed: the weather on a planned outdoor workout now follows the units you picked in the app. If you set Imperial but your device region is metric (or the other way round), it could show °C and km/h instead of °F and mph. It now uses your chosen units.
Readiness score 2.0: the score now reflects purely how recovered your body is - your plan no longer drags it down on rest days. Tap the ring to see every factor behind today's score compared with your personal 30-day baseline. Your morning check-in completes a provisional score, and once your morning data is in, the score stays put for the day.
Morning check-in gets its own quick sheet: tap the invite next to your readiness ring and log how you feel in 30 seconds, with your saved answers prefilled. The check-in invite now also shows on days your score is already set, and answers you logged in Intervals.icu count automatically. Plus: the app version is now shown at the bottom of Settings, and the check-in buttons align neatly in every language.

Weather for your upcoming outdoor workouts (Pro): open a planned outdoor ride or run to see the forecast for exactly when you'll be training, based on your location. You get temperature and feels-like, an hour-by-hour strip from your start time so you can see how conditions change during the session, wind speed and direction, rain chance, UV and more.

Coach+ now runs on our streamlined coaching toolset for faster, more reliable answers. Max members can also connect IntervalCoach to AI assistants like Claude and ChatGPT (beta) — see Settings → Beta.

Fixed: when you ask Coach+ to adjust a workout in chat (add a set, change intensity, move a session), the Approve button now shows up reliably so your change actually applies.
2026.6.40 6월 24일
Your Daily Outlook now shows your full coaching read the moment you open the app, instead of a short generic line until you refreshed by hand.
Completed strength and gym sessions now show an estimated recovery time.
On an activity, swipe in from the left edge to go back to the previous screen.
Completed activities now show only post-workout nutrition advice, not the pre and during tips.

Behind-the-scenes reliability improvements.
Reliability work behind the scenes: better freeze and crash diagnostics so we can spot and fix any app slowdowns faster. No visible changes in this build.
2026.6.36 6월 21일
macOS: 'Manage on web' now opens your default browser instead of a second app window, 'Manage in App Store' opens the App Store subscriptions page, and the subscription help text no longer says 'iOS'.
• Apple Watch sync now keeps your interval structure, so sprint and interval sessions no longer collapse into one averaged block.

2026.6.34 6월 19일

Activity detail: HR, power, speed, cadence and altitude charts, plus a power-curve with a fresh-vs-fatigued durability view. Pull down to refresh an activity.
Activity charts now scrub: drag across a chart to read the value at any point. HR/power/speed/cadence/altitude charts and the power-curve durability view.
• Apple Health-workouts syncen nu vanzelf op de achtergrond, direct nadat je klaar bent. Je hoeft de app niet meer te openen.
• Activiteitsgrafieken: sleep over een grafiek om de exacte waarde op elk punt te lezen.

The readiness score now appears right on your home and lock screen widget, and the motivation check-in matches the Intervals.icu scale.

Activity detail now draws your personal recovery curve and shows the recovery card higher up.
2026.6.27 6월 17일
