Hi everyone,
I’m an endurance athlete and iOS developer, and I’ve trained with intervals.icu for several years. I wanted an iPhone app for it that puts my plan and my week first, so I built one. It’s now at a point where I’m ready to share it, and it’s available on TestFlight.
The app is called Cadence. (It’s not related to the Cadence bike computer app for Android.) It opens on today: the planned workout, the week against your targets, fitness, fatigue and form, and your weekly streak. From there you can:
- see the week in a calendar, and move or add workouts
- set weekly targets and change them as the week goes
- follow your training plan week by week towards your race
- review activities with map, laps, power, pace and heart rate
- arrange an Insights board with the cards that matter to you
- keep a weekly streak, where one session in a week counts
- browse your workout library and public plans, and write workouts in the intervals.icu workout syntax
- add widgets to the home screen
What it doesn’t do: it isn’t an AI coach, and it doesn’t cover sleep, HRV or readiness. It also doesn’t calculate any scores of its own. Every number comes from intervals.icu, with the same names and values as on the website.
If you use Intervals Companion, Cadence isn’t meant to replace it. Companion covers a lot, including Apple Health and Watch sync. Cadence focuses on the plan and the bigger picture.
Cadence is free. There’s no separate account and no server in between. The app connects directly to intervals.icu, and you sign in with your intervals.icu account.
Planned next:
- heart rate bests, which a few people here have asked for
- a setup that builds your Insights board from your training history
- applying a plan to your calendar from the app
- generating weekly targets for a plan, like the target generator on the website
- shifting or restarting a training block after illness, with a preview of every change before it’s applied
- strength workouts with exercises, sets, reps and a muscle map
Thanks to David for intervals.icu and its API. This app wouldn’t exist without them.
