Katan adds a large TV screen to your photography experience. It makes mobile photography more comfortable, social, and fun. See photos better yourself, and discuss them with family and friends while enjoying your time around a TV!

Katan offers the full photography workflow, from selection to adjustments, with a large TV screen. It works directly with the Photos library, and the iCloud library (if enabled). Katan adjustments are non-destructive, all the image settings are saved in the Photos library. They are synchronised between your devices with the enabled iCloud photo library. You can open adjusted images later in Katan or in Photo Sense, and keep working from where you left, on any iOS device!

Katan works over your local Wi-Fi network with:
• Apple TV
• Many modern smart TVs, for example Samsung, LG, Sony, Panasonic, and Philips TVs
• Chromecast
• Android TV
• Other devices supporting DLNA or Google Cast

Please download Katan for free and check if your device and network setup are supported.

Feature highlights:

• Show photos on TV screen
• Play slideshow
• Compare multiple photos side by side
• Zoom in to inspect details
• Zoom in two images side by side to compare details
• Mark library photos as favorite, delete unsuccessful ones
• Enhance photos using automatic and / or manual adjustments
• Crop, straighten, transform images
• Give photos an artistic touch with creative effects
• Copy image settings and use presets to save time

And whatever you do, see the result immediately on a large TV screen!

Screen Size


Easy to install! But the mirrored pic on Samsung Smart TV is smaller than may laptops... ?? So what’s the point? Maybe developer will tell me how to enlarge or update. Tease that the app is free - Katan watermark banner on bottom of every pic unless you pay $3.99

Developer Response

Hi, thank you for your review. By default Katan generates 1080p images and sends them to TV. Some 4K TVs don’t show 1080p images full screen. Probably also your case. I think there are 2 options: 1. Configure your TV to show smaller images full screen; 2. In Katan preferences, select the image size of 4K instead of 1080p. This, however, may be difficult for older iPhones/iPads, especially if you are using adjustments...

The app is free to make sure it works with your TV (every TV is different!) before you pay.

Finally! An app that works easily

Finally an app that works easily without charging an arm and a leg.

Won't cast for slideshow


No seamless movement from one photo to another. It will only cast one photo then goes back to live tv before going to next photo. Also will not cast in order you have in your album. Do not recommend.

Hi, thanks for your review. The photos are currently ordered (and presented) by date, we will investigate if possible to change it. Switching back to live TV after showing a photo is definitely not what is supposed to happen. We have tested it on over 10 TVs of different brands and models, and never observed such behaviour. Could you please let us know what device you are using (
