Both the Apple Watch Series 12 and the Fitbit Edge are designed to do more than just count your steps, calories and sleep. They can both track multiple sports, but which one comes out on top in the water? I swam 1400 metres with both devices, using my Speedo smart goggles as the control — read on to find out more.
Before we dive into the data, check out our Apple Watch Series 12 review and Fitbit Edge review on Tom’s Guide here.
I swam 1400m with the Apple Watch 12 and Fitbit Edge: Here’s which fitness tracker came out on top
Let’s start with how these trackers measure your swimming workouts. Both use an internal accelerometer and gyroscope to recognise arm pulls and calculate how many strokes you take per length, as well as your stroke rate (strokes per minute). That said, there is a slight difference between the two trackers.

Before starting a swim workout, the Apple Watch Series 12 asks you to confirm the length of the pool you’re swimming in. This means during the workout, you’re able to see at a glance how many lengths you’ve swum. The Fitbit Edge doesn’t have a similar feature. When you get out of the pool, the Apple Watch will also give you a breakdown of how far you swam in each stroke, whereas the Fitbit Edge doesn’t.
As a control, I used my Speedo iQ Vanisher 3.0 goggles. These smart goggles give you a wealth of data when you’re back on dry land. As well as your pace, distance, and how long you spent resting at the side of the pool, you’ll also be able to see your head position, breath time and distance per stroke for each stroke.

As you can see from the data, the Apple Watch Series 12 was pretty perfect in the pool, measuring exactly what my goggles did. While the goggles don’t record heart rate, according to my Oura Ring 5, my average over the course of the swim was 129 beats per minute.
The Fitbit Edge, on the other hand, recorded a longer swim, and therefore a few more lengths. It would be nice to see stroke data on the fitness tracker, but again, I’d argue that the Edge is designed for the casual swimmer, not someone looking for a wealth of data.
Either way, I was impressed with the accuracy of the Apple Watch in the water. Being able to input the length of the pool and see at a glance how many lengths I’d covered allowed me to listen to my podcast (the Shokz OpenSwim Pro headphones are still my go-to) without having to keep count. During most swim workouts, I typically switch strokes every 10 lengths, so it’s a good addition to have.
I’ll be continuing to test wearables in the pool, but which of these devices would you be more interested in? Let us know in the poll below.
