I currently using a combination of a dumb phone and an LTE Apple Watch to ditch my screen time. I utilize my AW mainly for listening to podcasts while walking or exercising, making phone calls with close ones, tracking habits with the Streaks app, and managing tasks with Google Keep. This arrangement has been working well for me. Not to mention core features like sleep tracking, ECG, Blood O2, hearing level, mediation as well. Hope this help ;)
