I’ve tried all the top rated free (and most of the paid) photo editors available on iOS. Without going with something like photoshop, this app gives you everything you need to make your photos pop. Very simple interface, and extremely powerful. The last photo editor that you’ll ever need.

It was good before version 3...

MaxCurve is one of my favorite photo apps, but I am frustrated by this new update. Everything is just way less user friendly like it took a step backward. The user interface is super annoying and more difficult to navigate through, too busy, and the undo button is very frustrating because it isn't specific to each component of the edit but the whole photo itself. The way undo worked before was one of my favorite things about the app because it made it different from the other editing apps. I want it to go back. It also doesn't look nicer so I really don't understand what happened... it was so good before I don't get why it changed. And I am not a fan of how the graphs are on top of the picture rather than below. Lots of unfortunate updates. The editing capability itself is great, and I like the white theme option, but other than that, I'm pretty disappointed.

Hi, sorry for this trouble. I really made some changes for this app and I kept some for old users. You may change the toolbar into full mode by dragging the line bar on top of the toolbar. So the curves can't cover the pictures. As the undo button, I have to say it's from the most of other image editors and you will get used to it. Thank you.

Do you have to hit me with rating nags with every version update on every device? Usually the first time I open it too? How little do you have to care about user experience to obsessively harass PAYING customers to rate the app over and over and over again. Do you really think that yours is the only app doing this? Once upon a time, the customer was king. Now she's just a tool to feed the narcissism of the business. So, there's you rating. Again. I'll be sure to rate for each version update, before even using the new version. Because, you know, you care so much about our experience, you want to hear about it before we even have it. Now THAT'S dedication.

Developer Response ,

I'm sorry. I'll close the repeated rating warnings.
