Create your own dynamic desktop wallpaper (time-shifting/solar-shifting) on macOS Mojave.

Dynaper makes it easy to create a native time/solar-shifting HEIC wallpaper that changes throughout the day. Wallpapers made by Dynaper are supported by macOS Mojave and can be set as wallpaper in System Preferences.

Simply drag&drop your images and change the display time for each image. Dynaper will change time automatically if image contains EXIF metadata or contains time suffix in the filename. For a quick time change use the autosuggest feature. For solar-shifting wallpaper run Solar Wizard where you can export it.

Dragging image out of Dynaper will create time-shifting text that contains normalized time and parameters that one can use for manual HEIC creation.

Helper tools:
- time helper (convert time to normalized time)
- solar helper (convert location to solar data: altitude and azimuth)
- solar wizard (convert many locations to solar data: altitude and azimuth)
- HEIC metadata (view HEIC metadata used for wallpaper display)

Solar Wizard is accessible from top menu (Utilities-> Solar Wizard).

Automatic Time Detector:
To save your time Dynaper automatically recognises timestamps in your filename or metadata. If your filename doesn't have valid time Dynaper will look at EXIF metadata (date of creation) to find valid time. Just append your filename with suffix HH_mm, where H is hour and m is minute. 24 hour format is being used for detection and last 5 character of filename are being checked.

Example of valid filenames:

Please note that exported HEIC images include watermark. Removing the watermark is possible with in-app purchase.

Example of image display time:
1. 00:05AM-01:00AM (for time 00:05)

2. 01:00AM-03:00AM (for time 01:00)

3. 03:00AM-04:00AM
 (for time 03:00)
4. 04:00AM-00:05AM (for time 04:00)

What’s New

Version 1.3

- solar wizard to easily create solar-shifting wallpaper (Utilities-> Solar Wizard)
- ability to set as wallpaper during export (great for beginners)
- HEIC metadata preview (Helper)

- incorrect time parsing from EXIF (timezone issue)

Great tool, preview broken

I've been able to create and use a custom HEIC file, saving it to the Photos folder in my Home directory. But when I select it in the Desktop tab of the System Preferences, the preview image is from the system mojave.heic file, not the custom HEIC file I select. It still displays correctly on my desktop, which is what really counts, but it would be helpful if the preview image was correct ... especially once I start making multiple dynamic wallpapers.

Developer Response ,

Hi, thanks for feedback. The preview in System preferences is broken. However, the wallpaper is correct. I hope Apple will update macOS to fix the preview in System Preferences.

Works, but...

This app works, but includes a watermark until you purchase it. The app gives you several ways to buy it, but never tells you how much you will be charged for it. How did this get past the App Store?

Developer Response ,

Hi there, thanks for your feedback! We developer team sincerely value your opinion and will improve on the apps for the upcoming version 1.2.1.
