Editing photos on the iPad has many advantages: It's more portable than editing on a computer, and you can also edit a mixture of photos from your smartphone and camera RAW files. The App Store has tons of great photo editing tools that take full advantage of your iPad's features.
Lightroom CC is an all-time favorite iPad photo editing app for many reasons. The interface is easy to navigate, and you can also sync your edits in the desktop and smartphone apps in real time. Furthermore, you can use the app in Adobe Photography Plan along with Lightroom Classic. We recommend using Lightroom CC and Classic together for more comprehensive editing.
It's easy to transform your photos in Lightroom with the many presets in the app; You can even ask Lightroom to recommend specific settings for your photos, and you can add your own settings as you develop your photography style. You also have access to many of the same features as in Lightroom Classic, such as color grading and camera profiles. You can adjust some aspects of the photo, such as reducing noise and removing chromatic aberration. Both are available even when you import photos from a smartphone.

2. Apple Photos
While Lightroom CC is great, you don't need to pay for photo editing software to adjust images on your iPad. The Apple Photos app can be used in many situations. If you're new to photo editing, you should start with Apple Photos and then invest in another tool once you've learned the basics.

When you edit with Apple Photos, you can use many of the best iPhone camera filters for photos on your device. This is the most popular feature. It works really well on both smartphone photos and JPEG files imported from Fujifilm cameras. Just like when editing on the iPhone, you can adjust the intensity of each filter used. To compare with the original photo, just touch the photo.
Comparing VSCO and Apple Photos is a good idea before choosing which app you'll stick with. VSCO has many advantages. For example, while many VSCO filters require a premium subscription, the free options available are also very good. VSCO's filters are more “artistic” than Apple Photos (and even many of the filters you'll find in Lightroom). They also look great on photos taken with smartphones and cameras.

VSCO also gives you access to many cool sliders; For example, the Fade tool to give your photo a more blurred look. This tool is especially effective when taking high-contrast photos and wanting to reduce the overall effect, and is also great for creating a vintage look.
Photoshop Express is one of Adobe's valuable mobile apps and a great companion to Lightroom and VSCO. Sometimes you can use all 3 tools together because there are specific things that Photoshop Express is better at than others. One example is that cropping photos for social media content in Photoshop Express is much easier, thanks to its customizable preset settings.
One thing people really like about Photoshop Express is how easy it is to edit specific objects and subjects in photos. You can usually select the object you want to edit when you select the slider; You'll see thumbnails for each object.

If you don't want to pay to access Lightroom CC, Darkroom is one of the best alternatives. The interface is very similar, with many tools – like Contrast, Clarity and Highlights – identical to what you'll find in Lightroom. A particularly popular feature in Darkroom is that you can segment in between Highlights and Shadows to add as many colors as you like.
When you want to quickly adjust the overall image, use Darkroom's preset settings.

Editing photos on the iPad offers many advantages and flexibility. After trying many different apps, you should have no problem finding a tool that meets your needs. While some apps require a subscription to access all features, that's not always the case. And in many cases, you'll find what you need for free.
