WorkOutDoors - low price, no sub required.
Fantastical - sub not required
Lumy - sub required, but cool complications.
Those are the ones I would recommend. I have others, some require subs, some dont. But most are pretty user specific.
Lumy doesn’t have a sub, but it is a paid app. One time fee though.
I forgot. Still more than worth it for me for some cool complications.
