### 5/5 — Excellent! Near flawless

*2025-06-30*

Simple and easy,  fast and straight forward.  The zoom area once you get close is a nice touch.  I still would like full control to zoom into picture entirely, versus only a certain area. But pickers can’t be choosers.  It works exactly as you would expect to do a simple background blur. I am not submitting stuff for front page of a magazine. It did what I wanted and needed.  ZERO COMPLAINT.

### 5/5 — Great app

*2024-08-06*

Great app, very simple yet does its job and exceeds expectations. It would be nice to have some transparent image support

### 5/5 — 5 stars

*2021-05-25*

I love this app. It’s easy to use and works really well. I do wish that you could adjust blur depth by a number scale. Like 1 to 100 or something, but even that isn't a big deal. I like this app so much, I’d pay for an ad free version. Please make one^_^.

### 5/5 — Great!

*2019-01-31*
