SwimLog - Swimming Assistant

Track your swims, count laps, analyze your pace in real-time. Your ultimate companion in the pool.

SwimLog is an intelligent training companion designed specifically for swimmers. We don’t just record your data — we help you “read” it. Using high-precision sensor data collected by Apple Watch, SwimLog provides multi-dimensional analysis that goes far beyond native apps, helping you swim faster, farther, and with less effort.

Still just counting laps? Your swimming data can be so much more exciting. Connect your Apple Watch and let SwimLog capture every moment of joy as you dive in. Whether you aim to lose fat and get in shape, or to swim freely in the open sea, SwimLog is your indispensable companion in the water. With minimalist design aesthetics and a powerful analytical core, we’re redefining the swimming tracking experience.

Why choose SwimLog?

Visible fat-burning efficiency Accurately captures your “optimal fat-burning heart rate zone.” It not only tells you how many meters you swam, but also how many calories you burned. Watch the fat melt away with every stroke — making persistence easier.

Heart rate recovery health assessment What is your body telling you in the minutes after exercise? SwimLog automatically monitors your heart rate recovery rate, visually displaying your cardiorespiratory fitness level so you always know where you stand.

Minimalist design meets aesthetics Say goodbye to cluttered dashboards. We use the most intuitive colors and animations to show your “energy reserve” and “body battery.” Simple and easy to understand — even beginners can grasp professional insights.

Smart workout journal Automatically writes a daily workout comment for you. Whether you were “on fire” or “feeling a bit tired,” it gets you. Paired with beautiful shareable cards, every check-in becomes a ritual.
