1 star
i really like this app but it’s heart shattering when you’ve been editing for over an hour then one wrong move can get your entire video deleted.
Junk Now!
My subscription ends in Dec 21st and I won’t be renewing. The old app was better for blurring. Using the video to slide with your finger was much better. You have the control. This new one is too fast and it doesn’t blur slowly. Too bad, I’ve had this for a few years. Completely redesigned it. Bye!
Doesn’t even work.
Bought the premium package, when I selected a video to edit it just reverts back to the home page and doesn’t load the actual video.
Won’t save
My video won’t save
App crashes when trying to save video

Straight trash
Not accurate whatsoever I do not recommend this app at all!
Doesn't work
Bad
Horrible!
awful, every video I made did not have the blur as was supposed to, just a black screen on the side of the thin video. :) I boo this app.
Export half/screen
I’ve tried to find out if the export gets better when you purchase? I’ve seen a few reviews that state the exported video is half black screen and that’s what mine is doing. Is that how the app saves? I’ll revise my review if I’m wrong.
Do not use this app
This app does not work without the user investing a lot of time and even still it’s difficult to use. In multiple test videos the Blur tried moving with the face and struggled to stay with it and flickered often showing the full face with no blurring.I took a chance and paid for the year premium package and I’m very disappointed I did so. It’s not worth the money at all I do not recommend this app.
Impossible to use
Not intuitive AT ALL! Like zero directions, not easy to figure out. I just wanted to blur someone’s phone number in two seconds of one video and I could not figure it out.
Not worth it
I paid to download and it refuses everytime after hours of waiting for it to load all the way. What a waste of time and money
Still buggy. Changes aspect ratio when saves
It doesn’t work properly
Not user-friendly whatsoever
This app is not user-friendly at all. I spent an hour trying to find tutorials online but there is nothing. There’s no tutorials by the app manufacture either. I spent an hour and a half trying to figure out how the controls of this app work. I cannot emphasize the level of frustration this app has caused me until I finally was able to figure it out.
Awful App
Every time I finish adding blur to my videos and try and save it, the only video that ends up saving is just a compressed version of the old video with a black bar across it
Horrible
I’m trying to use it and it keeps crashing then when I try to download it .It keeps telling me to check my settings and allow access when it’s already allowed
worst app
poor quality. doesn’t work.
Crashing
The app is cool but it just keeps crashing and I can’t finish a simple video edit
Doesn’t work
I’ve been trying to use this app. As soon as I put the blur effect on the video the whole thing freezes and won’t let me make any changes, and i mean any. I can’t even save the video because it won’t let me click anything, everything freezes. Idk how anyone gets results from this app because that’s all within 30 seconds of editing
Tons of bugs
This app is full of bugs. It crash 4 or 5 times while editing my video and never saved my work so I had to start over each time. Also after hours, I finally finished the video. The app gives me an error every time I try to export the video so the app is useless. Don’t use this app, find something better and don’t waste your time
Idk
Im a fanpage of tiktok and I need to add blir at the beginning of my vids, but I can’t because every single time I want a video it says “video downloading from camera roll” and I wait about 3-10 minutes and it still says the same. Please fix this ASAP
Won’t let me save the videos
I’ve had this app for a few months, I rarely use it. It worked fine for a while (other than crashing a few times and making me start over editing entire videos, very annoying). Now every time I finish editing I click save; after loading for ages it gives me an error message saying I need to give the app permission to access my photos. It already has permission, obviously, how else would I be editing MY videos on the app? Still I tried toggling the permission settings, restarting my phone, re-downloading the app, nothing helps. This app is now utterly useless.
DON’T GET IT, SAVE YOUR STORAGE!
I don’t normally write reviews but I just want to give a heads up to future customers.
I just got this app for TWO very simple THINGS, to blur a video and export it. It completed one task, and I was like “Okay cool now let’s export it.” I exported it and it came out black half the way through the video and when I saw the video it was stretched and at the bottom of my screen. What a waste of storage.

Crashes
I just downloaded and Everytime I try to save the video it crashes and closes the app
Trash bro.
Stop sugarcoating this app 💀 it’s literally terrible
Don’t install
It’s horrible I tried making a video blur and when I saved it half of the screen was black the video was ruined
Crashing
I would love to use it but crashed from the start of downloading it
dumb app
it won’t let my save the video after i edit it.. how dumb
BAD
It takes SO LONG afore it to download from the iCloud
re
it isn’t working
Trash
This app is trash. Once i saved my video, you coukd only see about a quarter of it. The app cropped 75% of my video out.
Worst app i’ve ever seen
Made for to steal your data and get access to your details as the app itself does not work properly. Blur function horrible and bad design. Don’t download this
Not the best
For real tho, whenever I click on the video symbol it won’t click, and then when it does work it says downloading from iCloud and it just takes forever to load and just stays on the screen. It’s super laggy, I wouldn’t really recommend it because none of the buttons work!
kinda bad
it works but its just slow. if your reading this wanting to get it u can if you want,but its just not that good, its not bad but its not good. atleast it works.i had to wait more than 40 seconds just to finally get it blurry,but it works
Horrible
I have a iPhone 11 and it laggy as crap.
Absolutely terrible
app feels like it was made before iPhones even came out. Super buggy, slow, it’s also ridiculously hard to understand what you’re even able to do with this app. Like, is there no option to blur two spots at once with your finger? Or is there, but the app is so slow and buggy that it doesn’t work. I don’t know. Don’t waste your time though lol.
Hear me out...
So the face tracking is phenomenal but no matter how much blur you add, the final product of when you save it to your camera roll, it’s almost as if it gets rid of all the blur effects you put in it. It blurs it out in a million little dots so they can still clearly see your face even if you set it to blur out your face. I have only tested out the mosaic blur on face so you can try the others. Also it takes forever to save even if it’s a 5 second clip. Please fix
Abbsolute trash
Nevermind the awful 8-bit interface that requires 2 Elves and a magnifying glass to operate, whats the most irritating is how they try to be clever with their solicitation by asking you if you would like to “enable” certain features by pressing the button in the corner. LOL Don’t waste your time and please don’t make this app designer rich by buying anything from him. This is a get rich quick product that doesn’t hold up to it’s end of the bargain by working functionally.
Terrible
Directions on use are very vague, 2 sentences is all. Nothing to watch on how to use. I’ve wasted 2 hours trying to figure it out and I’m done. Saving edits to even see if they worked takes way to long. I don’t think this app is capable of doing the very fine blurs I need. I need very small areas blurred while moving and it’s just not possible to get good tracking. Fail
Terrible
Hard to work, and when you are done, it saves on your media totally wrong. I tried to add a censor on a video, and the black stripe was add to the side of the video. Nothing like i did. Several attempts and nothing
TERRIBPE
It’s GORSIUDHSHEID
DO NOT DOWNLOAD!
App crashes everytime you open it
Horrible
Crashes everytime you try to save the video.
Keeps crashing
Impossible to use. It crashes every time before I even finish working on your video.
Big Crash
I read the reviews before I downloaded the app and felt this was a good choice. Nope!!! Bad decision. I have only managed to get one video to save. Now every time I try to save a video the app crashes. So frustrating!
App will not save videos
This app constantly has glitch on top of glitch. It’s sad because it’s the only useful editing app. The new version currently force closes itself while attempting to save the video... don’t download. Look for different apps.
App crashes constantly
The app will only let me edit at the most one video and then it crashes every time I try to save the video.
Chashes. A LOT
I had barely downloaded the app and just started editing when it crashed. I opened it up. And does it again.
Not going to bother
Not going to bother
Ugh
I was using the app without issue then all a sudden it begins telling me it needs access to the photo album to save videos. I enabled this setting multiple times. I even paid to unlock certain features. Poorly designed junk of an app.
Low on power
Can’t tell what is going on. Click response is slow to non-existent. When things do respond it looks like a 8086 trying to run Windows Server 2016. If this app was actually designed for iOS, someone didn’t debug enough.
