Why buy each?

Fitbit Edge

Larger AMOLED display with always-on option

A 1.34" AMOLED screen, 46% larger than the Charge 6's, with an optional always-on mode and a physical button.

Built-in GPS, ECG, and an altimeter

Multi-system GPS for phone-free runs, an ECG app for AFib checks, SpO2 and skin temperature sensing, and an altimeter for elevation.

User-replaceable battery

Up to 7 days per charge, a 5-minute top-up for about a day of use, and a battery you can replace yourself when it wears out.

Garmin Forerunner 570

Multi-band GPS and Elevate Gen 5 sensor

L1+L5 dual-frequency GPS for precise tracking in cities and trails, paired with Garmin's most advanced heart rate sensor — adding skin temperature monitoring over the FR265.

Built-in speaker and microphone

A first for this price tier — take phone calls, use voice assistant, and hear Bluetooth audio directly from your wrist. A meaningful upgrade over the silent FR265.

Garmin Triathlon Coach

AI-powered triathlon training plans that adapt to your swim, bike, and run fitness — a key differentiator over the FR265 for multisport athletes.

Pick the Fitbit Edge if…

Anyone who wants a slim tracker with a screen, built-in GPS, and ECG rather than a full smartwatch. It suits Charge owners ready to upgrade, as long as they don't rely on Google Wallet payments or EDA stress scans. Works with both Android and iPhone via the Google Health app.
