Tracking heart rate helps you train by zones, control real intensity, and avoid overtraining. In running, triathlon, and hybrid training, this metric can significantly improve decision-making.
A chest or arm sensor also gives reliable data to evaluate progress: you can track aerobic development, recovery quality, and effort control across training blocks.

Chest vs arm accuracy: chest straps are usually more precise in rapid intensity changes. Arm sensors are often more comfortable and easier for daily use.
App compatibility: check Bluetooth and/or ANT+ support if you want pairing with watches, trainers, and multiple apps (Garmin, Strava, Zwift, etc.).
Comfort: if chest pressure bothers you, an arm monitor can improve consistency and user comfort.
Battery: evaluate battery life and charging or battery-replacement convenience based on training frequency.
