Is texting only option?

I’ve been struggling a bit with staying connected in my long-distance relationship. My partner and I have been texting all the while, while it worked when we were together but now living in different timezone I don’t feel like texting all the time its hectic and time consuming if I am busy, but I also don’t want to feel like a black box if I miss a call or don’t respond quickly.

I feel like sharing schedules could be a good way to stay in the loop without constantly checking in, but I’m not sure what’s the best way to do it. Do you guys just talk about it verbally or text? any good apps to do this ?
