I’m always looking for a self hosted pocketsmith alternative with a calendar like it. Thats how I use it best. I know I buy crap so categories are meh. But being able to pop ahead a month and adjust a bill or expense schedule to better align with fortnightly pay helps me. It also helps to remind me what I have not paid.

And to “predict” future balances. Sure a sheet can do that but I have always found a visual calendar works best with my adhd.
