A specialised app to instantly remove stars from your photo so that you can make intuitive changes to your galaxy. Then add back the stars.

Then combine the starless and star into a single image for your social media post. Traditionally, user has to download and remove stars on a laptop. This app makes it convenient and easy to do it on the phone using AI. Workflow: 1) Starless > Curve > Color 2) Star > Curve > Color 3) Both > Curve > Color Additional editing for Target and Sky in the Starless image if device has 4G RAM or more. Note: - The app is designed for seestar image of resolution 1080 x 1920 pixels. Larger image will need longer time to load and remove stars. Requirement: - App works best with 4G RAM and above. If the device has less than 4G RAM, it will use lesser weights for AI and produce degraded image. - Image is optimised at 1920 x 1080 pixels. Support: Please write to ustransit74@gmail.com. If the app does not process the stars in your image correctly, please send me your original photo. I will add your photo to the next AI training. A new app update will then be release.
