Swim Analytics Stop pacing your sets ‘on feel’. Swim Analytics calculates your real Critical Swim Speed (CSS) and the personalized training zones that follow — finally putting swimming at the center, not bolted onto a running app. Calculated locally on your iPhone, with complete privacy.
FEATURES
Stop training ‘on feel’. Swim Analytics calculates your Critical Swim Speed — the threshold metric swimming has been missing — straight from your own workout data, the same way running and cycling have had it for years.
7 personalized zones calibrated to your own CSS, not a generic benchmark — so every set has a clear purpose: recovery, aerobic, threshold, or VO₂max.
See whether your stroke efficiency and CSS are actually improving session after session — not just how many kilometers you've piled up.
No account to create just to see your own pool data. Everything is processed and stays on your device — nothing is sent anywhere.
Share your analysis with your coach or club in JSON, CSV, HTML, or PDF — all generated locally, on your terms.
Sub-0.35s launch with a local-first architecture. Your sessions are there the moment you open the app — no syncing, no waiting.
