TetherSwim vs Paceva

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.

Paceva is the triathlon and multisport analytics app for athletes who swim, bike and run. It brings swimming, cycling, running and walking sessions into one history and one combined training-load view, so you can understand fitness, fatigue and form across disciplines. NEW: ANALYSE YOUR TRAINING WITH AI Choose what to review (today's workout, your latest session against the previous one, this week or this month against the last) and the app turns your data into a professional prompt, in your language. One tap copies it and opens your AI assistant: just paste it into a new chat. ONE ATHLETE. ONE TRAINING PICTURE. A hard swim, an easy run and a long ride all affect the same body. Paceva analyses compatible workouts from Apple Health together instead of splitting your progress across separate sport apps.
