Oh nice, thanks. I haven't heard of the gotcha

1) Wonderful. It works better than regular pogo+ and the manufacturer makes available software updates. 2 and 3) I bought twice from Go-Tcha LED Touch Screen Wristband for Pokémon Go Plus Accessory https://www.amazon.com/dp/B071R3P45V/ref=cm_sw_r_sms_apip_YhKj8QzukzM7M. Why twice? Because it is EASY TO JUMP OUT OF THE BRACELET AND GET LOST! Be careful, I put a silver tape around it to guarantee it is firmly attached to the regular bracelet. There are some bracelet options (Mi2) sold at Amazon but I did not buy any. 4) Yes 5) you can lock your phone and keep Pokémon Go open in the background working fine on IPhone 7 or X (my experiences). Maybe other phones too. 6) see item 2 and 3

The reviews aren't that good. Is this for iOS or just Android?
The Go-Tcha is better imo. Auto-catches and Auto-spins. By default, it also has no buzzing or blinking. It looks like one of those fitness wristbands.
Will this work for you?
