### 2/5 — Does what it's supposed to

*2015-09-06*

I don't usually right reviews but... This app crashes so much I've redownloaded it 3 times. It does do the job. Maybe the pro version is better but I'm still scared to spend 3.00 and no be sure of the apps mistakes.

### 1/5 — Don't recommend

*2015-08-17*

Every Time I open the app it crashes...not worth the download. 😪

### 2/5 — It does not work

*2015-07-03*

It just has a bunch of ads and it would load my video that I wanted to change...such a waste!

### 1/5 — This just makes the whole video a black screen

*2021-02-10*

Doesn’t even time lapse don’t buy it’s useless please fix it sorry for the bad review but it doesn’t do any thing

### 1/5 — disgraceful

*2019-04-05, version 1.0.1*

how can an app like this even be allowed on the app store? 5 advertising pop ups in like 30 seconds from installation

### 1/5 — Bad experience

*2018-11-24*

Couldn’t even open the app. It told me to give it permission to access photos, which I did, but still, it didn’t work. Hope you have a better experience than I did.

### 1/5 — Steve.

*2017-10-28, version 1.0.1*

Seemed ok at first now rubbish, keeps kicking me out and now swamped with adverts.

### 1/5 — Very frustrating

*2017-09-12*

Would put a -5 stars if I could... I thought this app would be like an old one that I had on my old phone called "tempo", which was very easy, simple, and straight forward to use. This will not let me adjust the speed as I intend, will change things that I had already set, is overall very frustrating to use, and plays wayyyyyy wayyyy wayyyy wayyyyy wayyyy too many ads. 
The app keeps closing on me too. Extra frustrating because the idea is great, just very poorly done...

### 1/5 — This isn't even a app! It's just a place to find a bunch of ads

*2017-07-04*

There is a overwhelming amount of ads on this app! I tried to use it multiple time but all it did was crash and play more ads. I definitely do not recommend this app-all it will do is take up more storage

### 1/5 — This app is pointless

*2016-07-31*

I tried multiple times with multiple different speeds editing my video and every time I put a speed on it it wouldn't change. I would look at the videos I saved and even those hadn't changed speed. It's a joke

### 1/5 — TERRIBLE!!!!!!!

*2016-04-23*

It's the worst do not use it whatever you do! It's disappointing!😭

### 1/5 — Waste of time!!!

*2015-10-12*

This app is specifically just to play ads! From the moment you first open the app until the moment you delete the app. So many ads pop up it crashes constantly.

### 1/5 — All this app can do is play ads

*2015-08-27*

I haven't had it 5 minutes and am deleting. It has crashed twice, played 5 or 6 ads already, redirected me to my browser to download crap I did not ask for. In never actually slows down video. It plays my video in the original speed and plays ads.

### 5/5 — Great

*2016-05-18*

It was the easiet thing to useand costs no money!

### 5/5 — ?

*2016-05-14, version 1.0.1*

Feel like giving it a 5 don't be racist

### 5/5 — AWESOME!!

*2015-07-11*

It's not like the other apps where it crashes a lot and you can't load the video! It's very easy, and not frustrating. I get what I need done.

### 5/5 — c:

*2015-06-23*

it doesn't have a watermark and it's just all around great !!

### 4/5 — Ok😐

*2016-07-01*

I love this because it's an awesome time lapse or video editing app that I like but right now it's not the best whenever I try to open it doesn't let me open or it just crashes so I'm hoping there's an update but otherwise I love this app

### 3/5 — Ok👍👎

*2018-10-16, version 1.0.1*

Good when it doesn’t crash

### 3/5 — Eh

*2017-10-09*

it does the job pretty well but whenever i try to save my video, it keeps kicking me out of the app and it’s so triggering.

### 3/5 — Helpful but...

*2017-07-16*

I love this to make videos but whenever I exit out of the app I can never get back in. I have to delete and reinstall the app everytime. If it didn't do that then I live it!!

### 3/5 — Ehh

*2016-08-05*

Great app except for the fact that you have to do everything in one sitting. If you have multiple videos to do you can't close this app and come back to it because once you do, it crashes. So what you have to do whenever you want to use it is uninstall it and then reinstall it. It's a hassle. I hope they'll update this.

### 3/5 — Okay...

*2015-12-06, version 1.0.1*

It was okay before I started using it then when I went to actually use it, it would kick me straight out please fix this as I really want to use this app x
