### 5/5 — Does One Thing Really Well

*2025-05-31*

I didn’t think I’d have a use for this app, but my experiments with it have changed my mind. It’s going to add to my work with my photos.

### 1/5 — nicht gut gemacht

*2024-04-15*

werde mein geld zurück verlangen….

### 1/5 — Not the same as Photoshop or Lightroom

*2016-03-25*

Pro user: beware. Adjusting the top (highlight) or bottom (shadow) point does not behave like a normal curve. If you try to crush the blacks, it doesn't grab all the tones so the image looks almost inverted or something. Very weird. Same with the highlights. Will be deleting. Wasted 2 bucks :/

### 5/5 — Great

*2015-10-14*

Great app. Makes dope photos that are unique if you use your creativity and take your time messin wit it.

### 1/5 — 别买

*2015-10-11*

坑爹货，只有一个功能还敢卖12块，功能也不实用

### 1/5 — 不太值得购买，功能只有一个！

*2015-10-02*

曲线调节这是很多其它APP都能实现的功能，而且做得更好，这个只有这一个功能，体验也很一般，不值得付费购买！推荐picsplay或者Darkroom，Filterstorm等，功能多，体验佳！总之对这个APP很失望

### 1/5 — 毫無建樹

*2015-09-28*

只有一個功能都做不好，還敢收這麼貴。

### 3/5 — Good integration, touchy use

*2015-09-27*

The integration with the native photo app is great, but even on the iPhone 6 Plus screen I am having a hard time tuning the curves. Each time I tap the point handles it asks if I want to reset the point. 

Would be nice if curves were larger, or if there was a fine tune slider. Needs update for fine tune use.

### 5/5 — Pure.

*2015-09-26*

Simple execution. Fantastic results.

### 4/5 — Nice, focused app

*2015-09-25*

Great for quick curve adjustments from right in the iOS photos app. Wish the curves area was a little bigger; it's a little hard to make fine adjustments. Otherwise, love it!
