### 1/5 — Changed My Rating From 5 to 1

*2026-06-21, version 8.1.0*

I used to love this app, but like so many other slimy app makers, they pulled the old bait and switch move on me and after paying their $1.99 or whatever the cost was for premium back then, they raised the price to $12.99 or whatever it is now and rather than grandfathering in the ones there from the early days, they stripped my premium status away and required me to pay all over again. This is not unique to this app maker as this has happened to me more than once. But it is disappointing and frustrating to be on my calculator for 5 minutes just to double check a quick equation because I have to wade through a bunch of ads to get to the answer. I can’t reward underhanded customer care with my continued business, so it’s back to the stock iphone app for me.
