### 1/5 — Très de base

*2023-04-05*

L’application est très de base et n’offre pas les fonctions qu’elle prétend

### 4/5 — It works great

*2023-01-28*

The app works great, though it's s bit clunky. The developer does respond, though, so I'm hopeful things will improve.

### 1/5 — 分かりにくい

*2022-09-19*

操作が直感的に理解できない。

### 1/5 — Need to restart iPhone to access photo library

*2022-02-16*

The warp itself works really well. However I cannot easily access photos from the library. After two hours of playing realized the only way to get the option of loading new photos is to turn off and on the iPhone. Not what I expected in a paid app.

### 5/5 — Great app, does what it says

*2021-10-26*

I used this app to get the warp out of some documents I’d photographed for official purposes. They came out looking great!

### 1/5 — misleading

*2021-02-09*

does not warp it onlt shaves the photo

### 5/5 — Excellent

*2020-11-14*

Does exactly as it is advertised.

### 4/5 — Killer, but needs more UI precision

*2020-01-11*

I’d love to see an iPad version that works in landscape mode.  

Also, I need some way of bumping the corner targets by one pixel at a time for fine tuning.  

The value often jumps to something other than what I wanted as I take my finger off the screen.  I need to be able to get very precise with corner positions..

Excellent app!

### 4/5 — I really like the app and it works as advertised but...

*2019-10-12*

EDIT NINE HOURS LATER: I have no idea where the words “Another piece of crap” came from! I did not write them or do anything to add that comment to my review. BTW, it’s easier to send the image to yourself in a text msg then save to your camera roll from there. Using AirPlay was a dumb idea!
——————————— END OF EDIT ——————————

There are no instructions🙄 and that can lead to lots of frustration.
I’m using ios13.1.2 on iPad Pro 11 inch as of 10/11/19

After fooling around for 30 minutes, I finally caught on.
This is how I would place a lion picture on top of a jungle picture:
First think of WARP OUT and WARP IN as DESTINATION IMAGE and SOURCE IMAGE respectively. Also ignore the little arrows.
The jungle is the WARP OUT image. Lion is the WARP IN image.

When the app opens it wants you to choose a DESTINATION IMAGE.
Choose the jungle photo, crop if desired, accept the pic, set the four markers wherever you want the lion to be inserted later on.

Tap SOURCE IMAGE (actually WARP IN). It takes you back to the Camera Roll. Choose the lion photo, crop if desired then accept the picture.
The lion gets placed inside the four markers.

I don’t see how to save the image to the Camera Roll so I didn’t rate it five stars. I ended up using Air Play to send it to iPhone and back to iPad.

### 1/5 — Piece of crap

*2019-10-02*

Does not work in iOS 13. Warp out brings you back to photo gallery
