FAQ

How does Splitz figure out what my workout was?

It uses laps in your activity, how far and fast you ran, and some clever guesswork 🪄. It can detect most types of workouts including intervals and repeats, fartleks, and mixed-distance work.


What if I use auto-lap, or a pre-programmed workout on my watch?

As long as you also have lap markers when each rep starts and stops, it can figure it out — you can leave auto-lap on! Programmed workouts work great with Splitz as well (we actually prefer it 😉).


What if I recorded my warmup and cooldown in the activity as well?

That's totally fine, and in fact encouraged! It makes it easier to detect workouts, and saves your followers from a wall of posts 😉


Why didn't it update one of my workouts?

Sometimes the workout detection gets it wrong. I'm sorry when it does, and I'm working to improve it! 🚀


Can it also show my rest?

Not yet, but I'm working on it!👷


Can I add my own notes?

Go for it ✏️! Splitz won't do anything besides create the initial summary for you.


Do you collect any personal data?

Not at all 🙅‍♂️. Your activity info is parsed, then discarded.


Why do I need an account on here?

Boring technical reasons 💻. See above though, none of your personal data is collected or stored, and you can delete your account anytime.


Who made this? Why?

Splitz is made by David Cai 👋. I got tired of manually updating my workouts with splits and built this instead. I hope you find it useful as well!
