Just launched a Raster to Vector app on App Store

Hey, I'm Ehtisham Niazi and I just launched a Raster to Vector app for iPhone/iPad. If you are a procreate artist, I would love to know your feedback on what else could be improved in the vectorization process or configurations that are provided within the app. Link to app: https://apps.apple.com/us/app/pngtosvg-raster-to-vector/id6737781372
