My opinion is that it is very much work in progress, there is a huge way to go before it become a useful app. I will probably use it to edit images from my camera/mobile phone that I want to edit and upload to social networking sites.
The photo editing side of the tool is actually pretty good, but the complete lack of organization and restrictive saving of images is poor. It also has a lot of bugs that need fixing. I will keep playing, but I suspect I will wait for further updates before I use it more widely. If Apple had let me have a trial of it, then I would not have gone ahead and purchased.
Guys...it's a GREAT app. Use Photos for organization and iPhoto for editing and creating topic focused "journals" for sharing either on iCloud (free), Facebook (free), Twitter (free ) etc.
The editing tools are designed for touch and that alone trumps the new Photoshop Touch, which is much less intuitive.
And, it's only $5.
I like it.
I have so far been disappointed with this app for iPhone. The layout is not intuitive and so far I haven't been able to find a manual or help file to search through. The brushes are too difficult to use accurately on the small iphone screen. On some other apps, I've seen a small loupe magnifying glass pop up to the side to show exactly where you are painting. This would be very helpful for this iPhoto app, because it is extremely difficult to be accurate.
Overall, Snapseed and Touch Retouch have this beat by a mile, when it comes to user interface and functionality.
I am hopeful that Apple will make future updates that will improve this app. Until then, I will use it sparingly.
It's neat to play with, but it has a long way to go as far as workflow and organization. Right now it impedes workflow too much... if I'm on a trip, I can load my SD card into the camera kit and then upload all my photos on the iPad for editing, which is nice.
But then when I get home, there doesn't appear to be a way to synch events or albums back to my Mac where my main iPhoto library lives. I would have to import the photos again from the iPad to the Mac, delete the photos from the iPad, create the events/albums again on the Mac, and then synch the events/albums back to the iPad.
And who knows what happens to the photos I edit on the iPad, I guess they come over as duplicates.
For $5 I can't complain, and I'm sure a lot will be changed in future upgrades.
Also, I can't get Beam to work. I followed the instructions, but there's nothing that indicates HOW the beaming occurs-- I assume both devices must be on the same WiFi network but it's not explicitly stated in the online help. Or maybe it uses bluetooth. Or maybe it uses an ad-hoc WiFi network (like Airdrop). Who knows.
