Question about heart rate monitoring during workouts

I’m interested in buying the LEM15 but I heard heart rate monitoring during a workout isn’t reliable on a full android watch.

I use Strava and if this watch isn’t able to report the heart rate to this app then that’s a dealbreaker for me.

Are there any workarounds for this or are there any other watches that have this feature in addition to having a 4G SIM card slot?

This is a difficult one . These watches will obviously not be as accurate as a £ 350 watch . However for me they are near enough . If you use MRA it uses the inbuilt HRM which is cool


I feel, most of the android watches are not accurate as @Dr_Andy_Vishnu mentioned. I too have problems with Lemfo Lem12 pro, which always have funny readings.
