Versions

  • Can I use Hydra with any iOS device?
    You need an iOS device running iOS 8 or higher with back-facing camera, i.e. iPod touch 5th Generation, iPhone 4S, iPhone 5, iPhone 5c, iPhone 5s, iPhone SE, iPhone 6, iPhone 6 Plus, iPad 2, iPad 3, iPad 4, iPad Air, iPad Air 2 and iPad mini.

  • What do you mean by “universal app”?
    When purchasing Hydra, you can install and use it on any supported device. Let’s imagine you have an iPhone 6 and an iPad Air, you can use Hydra on both devices after purchasing it only once. You don’t need to purchase it twice - once for your iPhone and once for your iPad - like you have to do with many other apps.
    To make a long story short, by “universal app” we mean that a single application contains both versions (i.e. iPhone and iPad).

  • Is Hydra compatible with my iPhone 4 running iOS 7?
    No, it isn't because Hydra requires:
    • as hardware: an iPhone 4S / iPhone 5 / iPhone 5c / iPhone 5s / iPhone SE / iPhone 6 / iPhone 6 Plus or an iPod touch 5th generation or an iPad 2 / iPad 3 / iPad 4 / iPad Air / iPad Air 2 / iPad mini
    • as operating system: iOS 8 minimum.

  • Do you plan to release Hydra for other mobile phones?
    Why not? Please get in touch with us through our Facebook webpage or Twitter account.

  • Is Hydra also available on computers?
    Yes, it is. You can use Hydra for Mac on computers supporting macOS 10.11 and higher. More information about Hydra for Mac here.


Modes

  • How can I get more information about the various modes?
    Tap the question mark in the upper right corner of Hydra’s camera, and you’ll get more information about how each mode works, and what they are best suited for.

  • What is the compass icon used for?
    The arrow indicates the up orientation of the picture at the time it is shot. It rotates with the device when you turn it. You can force the up orientation in the saved image by locking it (tap the compass icon).

  • Is it possible to add information about the location where I took the picture with Hydra?
    Yes, there’s an option available for this in Hydra’s settings. When activated, Hydra will automatically add location information to the picture metadata.

  • How can I evaluate Hydra’s efficiency?
    You can save the original image so that you can compare it with the Hydra-processed picture. Check if the option is activated in Hydra's settings.



Issues

  • Why is the gallery not available on my device?
    It is not available if you use an iPhone 4S or an iPad 2. We had to remove this feature on devices having less than 512 MB of VRAM, or the app could crash under certain conditions.
