You can try Callipeg for free for 7 days, after this you can access Callipeg for 0,99€/month, 9,99€/year or as a permanent purchase for 49,99€. The purchase is made within the app (and not in the AppStore) when you open Callipeg for the first time or after the 7 days trial. Download Callipeg from the AppStore, open the app and choose the payment option fitting your needs in the prices panel. You will have to fill your Apple account information to purchase the app. Even if you purchase Callipeg from the app, it is still linked to the App Store and Apple is in charge of all the transactions.

Callipeg is currently only compatible with the Apple Pencil (1st and 2nd generations). You can allow finger drawing in the app settings in the Canvas tab which will allow you to draw with your finger or with another stylus, but there will be no pressure sensitivity.

Callipeg is available in English, French, Japanese and Chinese. The language depends on the Languages/Regions settings of your iPad. You can switch languages in the app settings located in the Settings app of your iPad.

Callipeg saves automatically your shot every 30 seconds and every time you go back to the Studio. The backup files are multiple .peg files which are saved every 30 minutes. You can change the backup parameters in the app settings > General tab. You can find these backup files in your Files app > On my iPad > Callipeg > Backups. If you want to secure your files even more, you can export your .peg files to another folder (in your iPad or in a Cloud storage). When removing Callipeg from your device, iOS also removes its folder and all the content (backups / logs / settings), therefore if you are planning to uninstall Callipeg, export your shots and save your backups in another location than the Callipeg folder On My iPad.

You can choose the definition of your shot in pixels. For example 1920×1080 pixels, 2K or 4K. The performance will depend on your iPad specs. The higher the definition and the more sheets and layers you create, the more performance and storage you will need.

Only the number of sheets matters. You can have as many layers as you want, until you reach the sheets limit. This limit depends on the storage of your device. The size of one sheet equals the length of the shot in pixels multiplied by the height of the shot in pixels multiplied by 4 bytes. Here is how to estimate your possible number of sheets depending on your remaining available storage : (remaining available storage in bytes / (height of your shot in pixels x length of your shot in pixels x 4)) / 3 = number of sheets you can add in Callipeg This calculation includes a rough estimation of the size of undos and backups, but this will depend on how many actions you do, the number of backups you have set and other conditions. So consider this as a very rough estimation to have an idea of how many sheets you can add. So, for example, if you have 50Gb left on your iPad storage and a 1920×1080 pixels shot, you can add (50 000 000 000 / (1920x1080x4))/3= 2009 more sheets in the app. The performance of navigation and fluidity of drawing will also depend on your iPad processor and RAM.

You can export to several files formats: 

  • PEG is the Callipeg file format. It can only be opened in Callipeg.
  • MP4 video format.
  • HEVC video format with or without transparency.
  • GIF animated image format.
  • PNG image format which can be exported as a sequence or a still image, with the possibility of exporting with the layer structure (one folder per layer which contains one PNG file per frame or per sheet.)

You can import PEG, image and video files from the Import button in the Studio. You can also import JPG and PNG images directly in your shots with drag and drop from another app or through the action panel of your sheets. You can also import videos directly from the video layers in the timeline.

We have beta testers from the animation industry to get the feedbacks we need to implement production features. The beta testing is not currently open to other artists.
