Boo!

I tried covering front camera..it works same ...just comes the boo and they will go.. No need of watching them..no face detection.

This is a fun app that uses the phone's camera to determine if you're looking at the screen. If you don't look, the screen will fill with little black puff balls. If you look at the screen, they will get scared and run away. That's all there is to it. It's fun to see the technology used in a creative way but there isn't a lot of long term fun here. It's worth trying but probably won't be an app you keep installed for long.

The idea is not bad but in my point of view it should be developed more. I think that this application does not have a purpose, a reason to use it. Why would I download it if I'm not going to use ? So I suggest that the developers restart from where they stopped and try to build more on it.

Installed the app and when I try to go on it it goes back to my home screen. It seems like a cool app so I give it a fair rating but would like to see this fixed if you don't mind

Good idea (which I understood from the store description) but no in-app help, info or explanation. And the creatures do not really get scared when I look at them. Maybe due to the poor quality of my front camera. And btw, I like the fact that the app is open source.

The characters are cute, but I'm not sure if the app is working for me. The characters slowly appear on screen whether I'm looking at them or not. They dont do much. They look around, they grow and they squint their eyes. That's it. Gets boring really fast. I look forward to anything like new animations, colors, shapes and such, but as of now I am uninstalling.

The animations are cute and they're sort of funny to look at sometimes. But it would be fun to have them as a lock screen or as a background on my phone rather than just an app. At first I had a little bit of lag but then I turned up my brightness and it was fine so it was okay but I like to have as a background or a gif or something .

I've looked à the camera, even reset my phone and re started the app. Still boo's... Guess it's not a bad thing... just not able to get the full effect.

Cute little app, but there's a bit of lag from when I look at the camera and when the boos run away. It would also be nice if you could set it as a live wallpaper or lock screen. Otherwise, great, though somewhat pointless, app.

10/10. Does what it says. For all those calling it pointless, read the description. It's an app for education purposes. It has algorithms for face detection and the source code is in link in the description.

I love it! I admit in a short time I thought about deleting I , but Then I wanted to try a little experiment. I thought let me see if this works on my cat And yes it does. It recognizes her face she was engaged with it the first time for 15 minutes. She loved it she just sat there watching it. When she would look directly into the camera they would run away. She would look at the screen like where did they go. She stares at it and stares at it. So I will be keeping this app. My cat has never been at this engaged with an app, even the ones designed specifically for cats!

This little thing can bring a very wide smile to kids and older people, even i love to play and scare them. Thanks for such an wonderful app

It's not meant to be an entertaining game. It's an open source code and others in the comments asking it to be a lockscreen or wallpaper - do that yourself, go ahead. The idea is cute and fun to play with.

If this could be turned into a lock screen, so only your face could scare them, revealing your home screen when they run away, that would be fantastic.

I just really love blobs. They make me happier than most things do.

Don't know what's happening? Or is it necessary to use this in day time

There isn't much to this game, you just either let the ghosts pile up and look around, or don't. Not very dynamic or interesting, but mildly cute.

Finally an app that explains my life right now xD. *Cries in the corner*

Great work dev! There's no cons of this app as per my opinion. There is nothing in this app, no story, no gameplay, no meaning, but I fell in love with this app within a minute. Just....... Great work dev!

A lot of people wouldn't be keeping this app for a while. As a lot of people have said it would be a cool idea to turn it into a lockscreen.

they dont get scared when i look at them. im using an asus zenfone selfie

Whenever I click the app it goes off and sais this. Unfortunately boo has stopped

It really looked like fun but when i installed it and tried to play it, it kept taking me out and saying it had stopped working. It keeps doing that when i try to play it.

It's a fun app but only 10 fill my screen. And there really isnt anything else to do. I wish we good touch them so they do different things. And get to certain levels somehow to be able to dress them.

The game doesn't work, those little monsters don't really run away, they just keep staring at me

I love this app its funny and cute it uses the phones front camra and when you look away they stay on the screen when you look there eyes get big and they disappear great android experiment nice to see how it works too.

This app is cute and funny but the little 'boos' take awhile to see my face. Its a really great experiment and I think you should keep working on it. Thanks

I've put in the reviews "only for my device's model" and noticed that every other user has the same problem. The app opens for a millisecond, and says "Unfortunately, Boo! has crashed." Please fix. I have a Galaxy On5 phone.

I can't see any Experiment in it . It's just a animation going on , with no user interference , what do I have to do , just gaze at the boring circles ?

Camera was on and i was well lit, oh well ¯_(ツ)_/ ¯

Fun little app! Cute and silly, the kids love it. Runs flawlessly on my G5! Thanks... Wonder what it may do and how it will progress in future development updates?

Can you fix where they do not run away

It works on gyroscope. I have held my phone in a non-vertical and non-horizontal position; now when I bring my face in front of the camera the Boo doesn't run. So nice try.

I love this game a lot! Their faces/bodies are so adorable! And their eyes! I'm gonna diee! It's really fun to see how many of them you can put on the screen before they go away!

Installs but only crashes upon open :( Nexus 7, stock, no root

I'll keep it on to get a Giggle from the little ones around me.

The boos are just so funny when they see my face. So cute

Crash after start Nexus 7 2013 Android 6.0.1

How come is this app only 83kb. Impossible :)
