TriHonu is the coach that acts: it builds your week, writes the sessions onto your watch and adapts them daily — so the judgment stays where it belongs.
Works with Garmin Connect™ · Apple Watch (iPhone app on the App Store) · Polar · Suunto · Zwift · Rouvy · Hevy · TrainingPeaks · Intervals.icu · Android app in design
First 50founding members get every feature and every coach — at the founding rate, locked in for as long as you stay.
Tell it how it went. It raises the week — and writes tomorrow onto your watch.
Other apps talk. TriHonu acts.
Generic AI apps suggest — then you retype it yourself.
Even the best coach can't be there for every decision in your day — and shouldn't spend their evenings retyping your week.
TriHonu acts across your whole training — plan, watch, nutrition, races — every single day.
A week with your coach
Not a feature list — one ordinary training week, and what the coach did in it.

It reads your night before it says a word
Sleep, HRV and yesterday's session come in from your watch overnight. The morning verdict is one line — go, ease off, or swap quality for aerobic — and the reasoning is a tap away.

The session is on your watch, targets and all
Every session is built to your thresholds and written to your watch as structure — the intervals, the power, the pace. You press start.
Ask it anything.
Real exchanges, re-staged with a fictional athlete. Pick one — every reply is something the coach can actually do.
It has range — and never forgets it's your coach
As a tri coach, you must also be good at latte art, no? Any coaching on this as well?
Ha — a coach who can't pour a rosetta has no business talking about pacing discipline. Honest critique: good contrast, clean symmetry, and you finished with a proper pull-through, which is where most people botch it. Push the design lower and start the pour centre-far so it lands centred — same principle as swimming: set up early so you're not correcting late. Now go get the real fuel in before that 17:00 run.Ha — a coach who can't pour a rosetta has no business talking about pacing discipline.

See what your coach sees
Your whole season in one place — your readiness, the week ahead, and a coach that acts on both.
Goal-relative readiness, per sport — it names your limiter, not a vanity score.A Build week balanced across swim, bike, run and strength.
Your watch
Works with the watch you already wear
Your sessions and recovery come in on their own. Where your watch allows it, your coach's plan goes back out to it.

Today, your coach and your week, native. A widget and a session reminder on your Lock Screen. Log a meal from the camera, a strength session set by set. Your sessions on your Apple Watch, your recordings back through Apple Health. On the App Store now.
The same app for Android, with Health Connect for your Galaxy Watch, Pixel Watch and anything that writes to it. Today, TriHonu already installs from Chrome as an app with notifications; the native app is being designed for the watches the web cannot reach.
“I've followed every training-plan template going, and I paid for personal coaches. None of them ever really had a chance to adapt to what my week was actually doing — the work trip, the week everyone's ill, the niggle that won't settle. Nobody can be there for every decision in a day. So I built the part that does the work, so the coaching could be about the judgment.”

Coaching that grows with you
Three levels, and every one of them acts on your training rather than just talking about it. Every sport you train is covered from the start — strength sessions from Performance up; what grows is how far ahead it plans and how much it takes off your hands.
Garmin watches connect through TriHonu's own Garmin app: your activities and overnight recovery come in from the day you connect, and planned sessions and routes go to your watch once you switch sending on. Older sessions come over from Garmin's account export, which you upload once. If you connected Garmin before the switch, reconnect it once. Apple Watch works too, through our iPhone app rather than that sync — there, your coach's next seven days (strength sessions too, from Performance up) appear in the watch's Workout app, and what the watch records comes back to your coach. Get the app on the App Store. Polar watches connect directly too: your sessions, sleep and Nightly Recharge™ come in, and you follow your coach's plan in the TriHonu app on your phone. A Suunto watch connects too: your sessions come in, and your planned sessions go to the watch. Zwift, Rouvy and Hevy connect for what you ride and lift indoors. TrainingPeaks receives your plan, so you can follow it where you already read your training — and a session you complete inside TrainingPeaks itself (a TP Virtual ride) comes back. Intervals.icu receives your plan as well. Suunto watches connect too, and we're working on COROS and Wahoo.
What does “it acts” mean?
The coach doesn't just advise — it builds structured workouts onto your watch, adjusts your plan, and runs your briefings and reviews. You stay in control, with one-tap undo. Writing to your watch is off until you switch it on — your coach never touches it without permission.
"Achilles was grumbling on the last kilometre." The niggle is logged, tomorrow's run becomes a ride at the same intensity, Sunday's long run stays on the trails. Nothing is lost; nothing needed retyping.

The long run — and race day, planned around it
The week ends where the season points: race-day pacing and fuelling from your own thresholds, updated as your fitness moves, so the plan you follow on the day is the one you trained for.
Most of this works on every plan. Race-day execution and the food planning sit higher up — the cards below say exactly what each plan includes.

The TriHonu app knows the fold: your plan, your day and your session are laid out for each way you hold it. In the app on the App Store now.
Your week beside your day
Hold it like a book and Plan opens on two pages: the week on one, the session you tap on the other.
Like a book: one page each
Hold it like a book and Today splits at the fold: how ready you are and today's session on one page, fitness and form on the other.
Half-open: hands off, eyes up
Stand it on the floor and follow along. The step, its target and the countdown sit up top; Pause and Next step sit in reach below. The strength logger works the same way.

Your coach's week, on your wrist
Wear an Apple Watch and no Garmin? That is all you need. Our iPhone app connects the watch in both directions — get it on the App Store.
Design mock-up — not a screenshot
Sessions in the Workout app
Your coach's next seven days appear in the Workout app on your watch, ready to start. Apple shows a week ahead, so that is what we send; strength and mobility arrive the morning they are due.
Your day on the watch face
Complications put last night's readiness, your next session, the week's load and the morning check-in on the face you already wear — and once today's sessions are behind you, tomorrow's first one.
Ask your coach from your wrist
Tap the coach on your watch face and speak, or ask Siri. The answer comes back in two or three short sentences, and it carries on today's conversation — the same one you see in the app and on the web.
What you record comes back
Workouts, heart rate, HRV, sleep and body measurements flow from the watch back to your coach — the morning call and the next change to your plan are made from them.
Wear a Garmin too? Counted once
When the same session arrives from both watches, we keep one activity and attach the other recording, so your training log never doubles.
Same tools and the same data behind every one of them — but not the same method. Each brings a different school of thought, so they genuinely disagree about what your week should look like. Pick the one you would actually listen to.

Prices per month, including VAT. Pay for a year and two months are on us. If you ever stop a plan, nothing is deleted.
Every plan starts with a 14-day trial for $1. When the trial ends it becomes the plan you chose, at the price above, and renews each month until you cancel. Cancel during the trial and it does not.

Everything in Ultimate — every coach, every tool, the most capable models and the largest allowance. What is locked in is the deal, not the figure: you pay half the Ultimate price for as long as you stay, whatever Ultimate costs later.
Every plan includes a monthly allowance of coaching actions — and the work your coach does unprompted, like your briefing and your weekly review, never counts against it.
Nothing you have to know in advance. If you already train with a Garmin, Zwift, Rouvy or Hevy account, connect it and your sessions arrive on their own — Garmin Connect™ through TriHonu's own Garmin app, so if you connected it before, reconnect once; Apple Watch works through our iPhone app, on the App Store. Polar watches connect directly too: your sessions, sleep and Nightly Recharge™ come in, and you follow your coach's plan in the TriHonu app on your phone. A Suunto watch connects too: your sessions come in, and your planned sessions go to the watch. No watch yet? Tell your coach what you did with a tap. And no test numbers needed: if you know your FTP, swim pace or run threshold, add them — if not, leave them out, and your coach works them out as it sees you train. TrainingPeaks connects both ways — we deliver your plan there, and a session you complete inside TrainingPeaks itself (a TP Virtual ride) comes back.
Is there an app?
TriHonu runs in any current browser — add it to your home screen and it opens like an app, on a phone, a tablet or a laptop. Apple Watch and Apple Health need our iPhone app, which is on the App Store. An Android app with Health Connect — for Galaxy and Pixel watches — is being designed; tell us which watch you wear.
Do I need a card?
Yes. The trial is a real subscription: 14 days for $1, on the card you enter at signup — one trial per person. That is what keeps the coaching actions from being farmed, and it is why the trial can simply become your plan when it ends.
What happens after the trial?
It becomes the plan you chose at signup, at the price above, and renews monthly until you cancel. We remind you seven days and three days before, naming the exact amount and the date.
Can I cancel?
Any time, from Membership, in two taps. A subscription runs to the end of the period you have paid for and does not renew; a trial you cancel does not convert. You get an on-screen confirmation with the date and time.
Which languages?
English and German — the app, the emails and your coach, who answers in the language you write. Prices show in CHF, EUR or USD depending on where you are.
Is my data safe?
Your training data is yours — private by default. Export all of it whenever you like, and delete it, or your whole account, yourself from Profile → Your data. No email to us, no waiting.
What if I stop paying?
Nothing is deleted. Your training, your history and your watch sync all keep working — the coach rests, and picks up where you left off whenever you come back. And once you have paid for three months, editing your own calendar stays yours for good, subscription or not. The one exception is a trial that ends without a plan: that account is kept for 30 days, then deleted, as the Privacy Policy says.
