That alternative comes with a $60/year subscription these days, though.
There are two apps I pay for that replace an app on my phone: $15/year for Overcast replaces Apple Podcasts and & $25/year for Transit replacing the transit function in Apple Maps (which I may be able to drop now that I’m on Google Maps, but I haven’t tried yet, and the app is so damn good I’m not sure I want to). Those are easily two of the absolute best and most used apps on my phone.
But if you don’t want to spend money on another vendor, or there is nothing suitable for the price you want to pay, at least the phone often has something serviceable.
