About this app
--- Art with ease ---
Create art with the help of your fingertip. It's easy, relaxing and satisfying!
Mandalas are beautiful pieces of art where a certain segment is repeated many times, which gives a wonderful visual effect. This app is here to make it easy for you to create Mandalas from your own images or images from the built-in image library. Select an image and play around with different parameters which you can adjust. You also can animate the Mandala.
--- Key features ---
- Load own images
- Customize different parameters
- Add effects (bloom, vignette, chromatic abbaration)
- Animate it!
- Screenshot and video recording (UI excluded, could be used for your projects!)
- Draw mode (Experimental)
--- Draw mode ---
I also added a simple draw mode which allows you to draw your own Mandala. It currently only has limited options.…

Five-star share of ratings

Method and limits
What a missing label means
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Limits of this report
- A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
- Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
- Not assessed is a state. It is never a zero and never a pass.
- A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
