For runners with a race on the calendar · 5.0 on the App Store · 14 days free, no card
Find out what your training is actually building for your race. In your first week, from the runs you’ve already logged.
Tempo’s Long Read goes through every run in full, remembers how each one felt, and holds it all against the goal you chose. Below: why your watch, your plan and ChatGPT can’t tell you this, and what it looks like when something finally does.

The answer is already in runs you’ve done
You’ve logged months of running. Somewhere in those files is the reason last month felt heavy, the reason your easy runs keep creeping up, and what your race still needs.
Nobody has read them that way. Not your watch. Not your plan. Not you, at 10pm, scrolling back through the week.
You do the work. Nobody tells you why it is or isn’t working.
The watch says readiness is green. Your legs say otherwise.
The race predictor gives you one time, last weekend’s run says another, and you don’t know which one to believe.
The plan is a static PDF that assumes a perfect life. The sick kid, the work trip, the week that wrecked you: none of it is in there.
So you go looking. You paste your runs into ChatGPT, and it forgets you the moment the chat closes. You ask online and get ten opinions from people who have never seen your training. You don’t want to bother your friends with every niggle again.
And underneath it sits the question every runner asks sooner or later: did I already ruin this, and can I still finish?
Meet Tempo: the running partner that reads every run
Your best friends don’t read every run. Tempo does.
Tempo is an app for iPhone and Android. It connects to your watch, reads everything you’ve already logged, and talks it through with you, like a running partner who has seen every session.
Not a coach handing out orders. A partner who tells you straight and leaves the call with you.
Why your watch, your plan and ChatGPT can’t answer it
- Your watch has the numbers, and no idea what they mean for you. It scores you against a population, turns your run into a colour, and has never heard a word you said about how it felt.
- Your plan app has your goal, as a schedule. The same plan everyone who picked that race gets. When life happens, it shuffles the session and never says why.
- ChatGPT has the why, but not your file and not your memory. You upload the week again every time, and the advice drifts from what you agreed. Ask it the question you want a yes to, and you’ll get a yes.
- And if you have a coach: keep them. Tempo reads along between check-ins and explains. Your coach’s plan stays as it is.
Each one holds one piece. None of them holds all three at once: what you ran, how it felt, and the goal you chose. Without all three, nobody can tell you why.
The Long Read
The Long Read: what you ran, how it felt, the goal you chose. Together.
Tempo is built around one move. We call it the Long Read.
- What you ran. Every activity file in full, synced from your watch: pace, heart rate, cadence, where the run started to fade. Not the summary.
- How it felt. Everything you tell Tempo: the niggle, the long run that fell apart, the call you made last week. Tempo remembers it.
- The goal you chose. Your race and your time, held against what your training shows: what the goal asks, what’s already there, what still needs work.
Tempo reads the three together, on every run, and tells you what they add up to. The reasoning is on the table. Disagree, and nothing changes until you decide.

Translated from Dutch: Good app. Yes, it uses AI, but it doesn’t just echo you to sound (overly) enthusiastic. Simply realistic, and flexible when you want to try a different approach, can handle more load, or need to ease off for a bit.

Built by a runner who got tired of guessing
I don’t have a coach who looks at my training every day. I wanted something that mirrors my decisions and helps me become a better runner. So I built Tempo. That’s why there are no famous coaches in the photos here.
— Dylan, founder
Tempo reads from Polar, Coros, Suunto, Wahoo, Fitbit and more. Your data is never sold, and never shared with advertisers or data brokers.
What changes in your first week
- You’ll know where you stand. What your recent runs say about your goal: what’s already there, and what still needs work.
- You’ll stop guessing which number to trust. Each morning’s numbers read next to how the runs actually felt.
- You’ll have someone to ask at 10pm. About the niggle, the missed session, the race next month, with an answer built on your own training instead of a generic rule.
- When the week goes sideways, you get a new week with the reasons, proposed from your race goal. You have the final say.
- Over time, you’ll spot the pattern yourself, before anyone points it out.
What runners say after their first read
Hele fijne virtuele sparringspartner. Dankzij tempo hoef ik nooit meer te piekeren over al m’n hardloopperikelen waar ik m’n vrienden niet mee durf lastig te vallen!
Translated from Dutch: Such a good virtual sparring partner. Thanks to Tempo I never have to fret again over all the running worries I don’t dare bother my friends with!

The offer: your First Read, free
Start Tempo free for 14 days. No card. Connect your watch, tell Tempo your race, and you get:
- The First Read. Tempo reads every run you’ve already logged and opens your first conversation with what it found.
- Every run read from then on, next to how it felt and what it means for your goal.
- A running partner to ask anything, any time, who has seen every session.
Even if you never pay a cent, you keep what the First Read told you.
Three things that come with it
- The goal check. Ask “is my goal realistic?” and get a range, the reasoning behind it, and the thing you’re already better at than you thought.
- The morning check-in. A short note each morning: what today’s session is for, and room to say how you feel before you go.
- The re-proposed week. Sick, travelling, wrecked? Tell Tempo what happened and get the week re-proposed from your race goal, with the reasons on screen.

Questions runners asked before they started
Which watches work?
Tempo connects with Polar, Coros, Suunto, Wahoo, Fitbit and more. Garmin and Apple Watch aren’t connected yet. If yours isn’t on the list, Tempo can still talk your training through with you from what you tell it, but the Long Read needs the files.
Is Tempo a coach? Will it write my plan?
No. Tempo reads your training and tells you what it adds up to. It can propose a week from your race goal, with the reasons; you decide whether to use it.
I already have a coach, or a plan app.
Keep them. Tempo reads along and explains; it never rewrites your coach’s week.
How is this different from ChatGPT?
Tempo reads the full file of every run straight from your watch, remembers what you said weeks ago, and keeps your goal in view, so you never paste or re-explain.
What about injuries?
Tempo never diagnoses. It remembers the niggle you mentioned and helps you weigh what running on it costs. For pain that doesn’t settle, see a physio or a doctor.
What does it cost after the 14 days?
€19 a month or €190 a year, or €9 a month with the early-adopter offer for as long as you stay subscribed. I’ll close it to new subscribers when I’m ready. The trial needs no card.
I’m not fast. Is this for me?
If you have a goal and want to know why your training works the way it does, yes. A first 10k counts as much as a sub-3.
What happens to my data?
It’s used to read your training for you. It’s never sold, never shared with advertisers or data brokers, and deleting your account deletes it.

P.S. The short version: Tempo reads every run you’ve logged, remembers how it felt, and tells you what your training is building for your race, starting in your first week. 14 days free, no card. The early-adopter offer is €9 a month while you stay subscribed; I’ll close it to new subscribers when I’m ready.
Or close this tab and run the next block the way you ran the last one: guessing which number to trust, and asking yourself at 10pm whether you already ruined it.
