iPhone App Review: Straighten Image
Monday, February 22, 2010 at 3:27PM | Glyn Evans 
About a week ago the developer of Straighten Image made the app available for free for a couple of days, and so during that time I grabbed myself a copy. It wasn't until I flew in to LAX on my way to PMA that I got chance to test this app out. If I was being honest I grabbed the app because it was free, but never got around to testing, and even expected it to be yet another low-res app, how wrong I was.
The app itself is a no frills, one trick pony app, that lets you quickly and easily realign the horizon, and straighten out any crooked photos.
To use the app simply launch the app and you will be presented with an almost black screen with a circular button in the middle that says 'Open Image'. Tap on this, select a photo you want to correct and then use the slider and grid combination that you are presented with to make adjustments from -45° to +45° degrees.
Above: Click to open, grid/slider to straighten, tick to saveI was amazed at just how quick, easy and simple this app was to use, but the most interesting thing, and more importantly omitted from the AppStore description, is the save photos are upscaled, and so on my iPhone 3G, were saved at full-res. Now I'm not sure if this app saves at full-res on the iPhone 3GS, so if anyone has an iPhone 3GS and this app, then maybe they could comment on the resolution.

Above: The same photo without the slant, or loss of quality or file size, and then processed with Perfectly ClearSo what do I think of Straighten Image?
Simply put i think this app is great, and whilst it may be a one trick pony app, it does what it does, very well; and gets my recommendation.

Thanks to feedback from reader Deborah Lattimore, it looks like this app does support full-res on the iPhone 3GS.

I agree, this is a great app. It does save at full-res on the 3Gs. Thanks for bringing it to our attention!
PS Mobile does this and more. So this app is pretty much useless
@Dixon. Thanks for the comment and I agree that other apps like PS Mobile do this and much much more, however sometimes a one trick pony app is all that is needed, and the ease and speed of some of these apps make them worthy of any iPhoneographers tool kit; and it was the apps ability to upscale without loss of quality and its ease of use that prompted me to give it my recommended award.
I find Cropulator more intuitive, and it's always saved at full resolution.
For me, this app is much more user-friendly than PS Mobile, because I prefer using the slider to adjust the photo.
Doesn't Crop Suey, by the same developer do the same..and more?
It's really a nice app,by this app one can realign the horizon, and straighten out any crooked photos and simple this app was to use......
Thankx for sharing
@Darren Stephens, yes it does, but I was reviewing the based on my requirement to a quick and simple correction app, and this works a treat, and also when I got the app it was free, but even despite that I think it is still worth the £0.59/$0.99 price tag.
