Features
Coaching that keeps up with you
Set a goal (a race, a target time, or just getting fitter) and Pacevi does the planning, every day.
A plan that adapts
Missed a run, ran harder than planned, slept badly? Tomorrow changes, and Pacevi tells you why.
Today's run at a glance
What to run, how long, at what pace or heart rate, with easier alternatives when you're not feeling it.
Your progress, clearly
Fitness trend, weekly distance, personal bests, heart-rate zones and your easy pace getting faster.
Recovery-aware
Resting heart rate, sleep and HRV (when your watch provides it) feed a daily readiness check: green, amber or red, with the reasons.
Works with your watch
Reads runs and recovery from Health Connect, intervals.icu or FIT files, and can send planned workouts to your watch through intervals.icu.
Make it yours
Arrange Home and Progress with the widgets you care about, in light or dark mode.
How it works
Three steps to your plan
No forms full of guesses. Pacevi learns from the running you've already done.
-
Connect your runs
Link Health Connect (Garmin Connect, Samsung Health, Fitbit, Polar, COROS and more) or intervals.icu, or import FIT files.
-
Pick your goal
Choose a race and target time, or simply get fitter. Tell Pacevi which days you can run and how long you have.
-
Run, and let it adapt
After every run and every morning, Pacevi checks your training and recovery and adjusts the days ahead.
Always explained
Every change comes with a reason
Pacevi follows proven training principles: build gradually, keep most running easy, space out hard days and taper before race day. Safety limits are checked after every change, including the ones you make yourself.

FAQ
Questions
Is Pacevi available on iPhone?
Not yet. Pacevi is coming to Android first, through Google Play. An iPhone version is planned.
Do I need a smartwatch?
A watch or phone that records your runs with heart rate gives the best plans, but Pacevi also works from distance, time and how hard each run felt.
Can I get workouts on my watch?
Yes, through intervals.icu. Turn on "Send my plan to intervals.icu" and your upcoming workouts appear in your intervals.icu calendar, which can sync them to Garmin and other watches.
Does Pacevi use AI?
No language models. Pacevi uses established training rules and small personal models that learn from your own runs, trained on your phone. Your data is never used to train anything anywhere else.
What happens if I change phones?
Export an encrypted backup from Pacevi, protected with a passphrase you choose, then restore it on the new phone.
Is it medical advice?
No. Pacevi gives training guidance, not medical advice. If you're injured or unwell, talk to a doctor or physiotherapist.
