Swim Analytics You Know Your Threshold Running. What About Swimming?
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
Everything You Need to Improve
Your Real CSS
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.
Training Zones
7 personalized zones calibrated to your own CSS, not a generic benchmark — so every set has a clear purpose: recovery, aerobic, threshold, or VO₂max.
Smart Comparisons
See whether your stroke efficiency and CSS are actually improving session after session — not just how many kilometers you've piled up.
Complete Privacy
No account to create just to see your own pool data. Everything is processed and stays on your device — nothing is sent anywhere.
Export Anywhere
Share your analysis with your coach or club in JSON, CSV, HTML, or PDF — all generated locally, on your terms.
Instant Performance
Sub-0.35s launch with a local-first architecture. Your sessions are there the moment you open the app — no syncing, no waiting.
