Before, during, after
A running companion for iPhone that I designed and built. It doesn’t track your run. It helps with the run itself: what today should be, a beat to run to, and something to make of it after.

At a glance
- What it is. A running companion for iPhone, for before, during and after a run.
- Who it’s for. Runners who follow a training plan.
- My part. All of it! I’m a design engineer: I designed it and built it in SwiftUI.
- Status. 1.0 is in App Store review. Fingers crossed!




Too many apps
For one training run I was juggling:
- A book’s plan, as a calendar file
- Apple Notes, to check off runs
- A metronome app
- A stopwatch for strides
- A weather app, for what to wear
Five apps for one run! So I built one for before, during and after.
Before the run
Open Day, the home screen, and it’s all there: today’s run from your plan, what the coach thinks, the weather, what to wear and how to warm up.
The coach’s call
The coach reads your recovery from Apple Health and calls it: “Run it” or “Take it easy”. Ask it anything! It took three tries: a score said “57%” almost daily, so I ignored it. Typing in my watch’s readiness was a chore. Now there’s no typing at all.


During the run
Running at about 180 steps a minute helps prevent injury, so the metronome keeps your cadence in check. It lives on the lock screen, because mid-run the app isn’t open! It starts at your last tempo, so there’s nothing to set.

Strides, counted
I used to sprint 20 seconds, hit lap, and lose count. Now Cado counts your strides, and you end each recovery with a tap, because recovery varies. Then a cool-down to finish. All from the lock screen too!
After the run
Draw how it felt, or something you saw, over your route or a photo from the run, and share it. This screen used to be a checkbox. Boring!
The plan ahead
Pick a plan from a book, like Pfitzinger 18/70, and Cado sets it to the mileage you’ve been running. Each run checks itself off from Apple Health, so Plan just shows what’s next. No logging!


What’s next
- Launch! 1.0 is in App Store review.
- Other runners. Get it into more hands and learn what doesn’t fit how they run.
- Keep running with it. Anything that feels off mid-run goes in Notes, and gets fixed after.
