I've got a Bip. Using the GPS to track running or hiking does use a lot of power. I need to recharge about every 2 weeks, tracking a 1-hour walk every day.

I do recommend it. Another differentiating factor is the display. The Wyze product doesn't indicate the display tech, but the Amazfit using e-Ink, so it's always on and has good visibility even in bright light, something that competitors like Apple (with its minuscule battery life and disappearing display) can't claim.

Just one point of clarification, the Amazfit Bip does not use e-ink. It's a transreflective LCD screen, kind of like the old Game Boy Advance screens. It's easier to see in bright sunlight, and always on.

Another clarification, the display of the Bip(and Pebble, Garmin and others) is not a transreflective type but a SHARP Memory LCD where pixels only need power to change their state but need almost no power keeping their current state, like e-ink, but better, so it looks like transreflective in the sunlight.

The transreflective LCD type of the Gameboy would absolutely nuke your battery life as it needs to be actively refreshed even on stationary images.

I'm deeply saddened this type of display is not more popular among wearables vs OLED. Who doesn't want 30 day+ battery life and always-on sunlight visibility?

Can you get your data to other apps like Strava, or do you have to use Amazefit's app?

The factory software supports Google Fit. I think various third-party apps, like "Notify for Amazfit" (which I use and recommend) can also send the data over to Strava.
