### 1/5 — Ruined.  Don’t Do it

*2026-01-04*

Once a great website.  Now a horrible app.  You get to test the app once then you have to pay 3.99 a month.  Cant really say if the app is good cause I used it for about 5 minutes.  The old website was great now it’s a pop up nightmare.

### 2/5 — Possibly useful?

*2025-07-21*

App no longer working, stuck in files screen with no way to get back to calculator tools.  Was fairly useful but nothing that an online tool can’t do.  Pricing not realistic.

### 3/5 — Eh

*2025-07-03*

Nice and I would pay 3.99 once but not monthly. Your’e high. Going back to free web version
