I recently downloaded a minimalist phone app that I love so far, but after the 7 day trial it'll be £20 for the year. This isn't wildly expensive but are there any other options to try that might be free/cheaper?

I've seen lots of people posting that they're developing apps but not sure what's what

Thanks!

Edit: there appears to be some confusion. This is an app that changes your phones UI to be less interactive. Rather than deleting everything, it gives you the option to switch between your usual setup and a minimalist setup. Great for people who aren't trying to go cold turkey
