When will Monzo be able to work with wearables like Swatch and Garmin then I can cancel Curve once and for all and stop paying twice for banking services
Monzo works directly with Apple Pay and Google Pay, so you could choose to use an Apple Watch or a wearable that supports Google Pay. I believe Fitbit is rumoured to soon be adding support for Google Pay.
If going the Curve route to use wearables without Apple Pay or Google Pay (e.g Garmin), I’m not sure why you need to pay twice? Curve has a free tier which includes use with wearables.
