Frequently Asked Questions

Can I use Garmin and Polar together?

Yes. Some athletes use a Garmin watch for outdoor adventures and navigation while relying on Polar for structured running training and its superior heart rate accuracy. Sathi.fit lets you connect both and view combined training data in a single dashboard.

Which is better for running?

Both are excellent running watches. Polar stands out with its Running Index, personalized running programs, and Precision Prime heart rate sensor. Garmin offers running dynamics, more GPS options, and Garmin Coach plans. Serious runners often prefer Polar for training intelligence; trail runners and multisport athletes lean toward Garmin for maps and breadth.

Which has more accurate heart rate tracking?

Polar's Precision Prime sensor is widely regarded as the most accurate wrist-based optical heart rate monitor. Garmin's Elevate sensor has improved significantly but still trails Polar slightly for wrist-only measurements. Both support external chest straps for maximum accuracy during intense workouts.

How does Sathi.fit combine Garmin and Polar data?

Sathi.fit connects to both Garmin Connect and Polar Flow via their official APIs. Your training load, heart rate data, GPS activities, recovery metrics, and performance insights are pulled into a single dashboard. You can view cross-platform trends and discover patterns across both ecosystems.

Which watch has better battery life?

Garmin generally leads in battery life, especially with the Enduro and Fenix series offering weeks of smartwatch mode and 40+ hours of GPS. Polar's Vantage V3 offers up to 40 hours of GPS, which is competitive. For ultra-endurance events, Garmin's solar charging models provide an additional edge.
