Swim Analytics turns the swims you already record into clear, actionable training insight — pace, CSS zones, splits, stroke data, training load and long-term trends. Private by design: everything is analyzed on your device. 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. BUILT FOR SWIMMERS WHO TRACK Import every pool and open water workout you record with Apple Watch or your favorite tracker via Apple Health. No manual logging, no account, no cloud. WHAT YOU GET • Pace and speed analysis per workout, per split and per stroke • CSS (Critical Swim Speed) estimation and personalized training zones • Training load (sTSS), fitness and fatigue trends week over week • Lap counts, distance, duration, heart rate and calories • SWOLF and efficiency insights to sharpen technique • Weekly, monthly and yearly progress charts • Open water and pool swims, freestyle to butterfly • Export any workout or your full history to CSV or JSON KNOW IF YOUR TRAINING WORKS Swim Analytics answers the questions that matter: Am I getting faster? Is my training load sustainable? Which sessions move the needle? CSS zones and load trends make it obvious — the same methodology coaches use, without the spreadsheet. PRIVATE BY DESIGN Your swimming history never leaves your iPhone. No account. No tracking. No servers. Delete the app and the data is gone. PREMIUM Swim Analytics Premium unlocks the full experience with monthly and annual plans, starting with a free trial. Cancel anytime in your App Store settings. Swim smarter with the training analytics tool built for swimmers, triathletes and open water athletes.
