PoolMate vs TetherSwim

The PoolMateSport and PoolMatePlus watches record your swim data. They give information such as Laps, strokes per lap, speed, distance, calories, efficiency, duration and more. You can upload this data to our swim analysis and logging platform mypoolmate.com with the app. This app and watch use NFC (near field communication) to transfer the data from the watch to the phone. You need to make sure your phone is an iPhone7 or above so it has suitable NFC capabilities. NFC needs to be turned on in your iPhone settings before use. You'll need to set up an account at mypoolmate.com prior to use and enter your account details in the settings page in the app. An internet connection is required.

TetherSwim is built for swimmers training with resistance cords, swim tethers, or endless pools. Traditional swim trackers can struggle with these sessions, giving you wildly inaccurate distances or ignoring your efforts altogether. With TetherSwim, your distance is estimated intelligently based on your real stroke count, SWOLF, and previous swim history — all from your Apple Watch. Features: • Accurate distance estimates – Uses your stroke rate, efficiency, and past workouts to calculate real swim distance. • Automatic SWOLF tracking – Measures your swim efficiency in tethered conditions. • Calories, heart rate, and more – Full workout data, just like in regular pool swims. • Exclude test swims – Keep your baselines clean by excluding warm-ups or experiments. • Strava integration – Upload your tethered swim sessions directly. • Water Lock mode – Automatically engages when you start, so your watch screen won’t go crazy mid-session.
