I recently moved to a place with harder water than I'm used to (more minerals). It tastes bad, it makes my detergents less effective, it forms soap scum everywhere, and it's definitely not good for my appliances. Does anyone have advice on how to deal with this in a cost-effective way?

I unfortunately can't install a point-of-entry water softener here. I can theoretically install point-of-use softeners for each of my appliances (bathroom sink, kitchen sink, dishwasher, washing machine, maybe shower), but the portable ones cost like $300+. I can't decide if it's worth the purchase. I also don't know enough about the different kinds or whether they're available in portable formats (reverse osmosis filtration, potassium chloride water softening, and sodium water softening; maybe others). Does anyone have recommendations?

I recently bought a showerhead with a better filter, which will probably help reduce skin irritation, but it can't actually remove calcium or magnesium. I can't visualize what a genuine point-of-use softener for a shower would even look like or how I would attach it to my showerhead, and I don't know where to get one that isn't just marketing fluff.

I have some CLR that I intend to use with my dishwasher, but I don't want to have to buy this stuff constantly (just another cleaning product in my cabinet). And I have a Brita for drinking water, but was thinking of getting an under-sink filter as I don't like waiting for it to refill; I have no idea how much to spend on this or which brands are best.

Happy to hear everyone's thoughts on household water management!
