I was hoping this could be a solid alternative to the original Card Centering Calculator app, especially since that one doesn’t let you save scans into a “collection” which I would like to do. Unfortunately, this app falls short in several key areas. First, it doesn’t use the iPhone’s ultra wide camera with macro mode, so scans come out blurry. The auto-detection feature also doesn’t work reliably. Worst of all, it constantly nags you to subscribe to a monthly plan. I am not paying monthly for an app that is essentially a copy of the free one. There are better alternatives.
Thank you for your feedback. As a solo developer, I’m focused on creating a better card centering calculator app and have recently updated the camera to use the ultra-wide lens with macro mode when available to improve scan quality. If you could share the specific cards you tested, I would be happy to refine the auto-detection algorithm for those cases. Please note that subscribing is not required to use the main “card centering” feature. I appreciate your support and am always looking for ways to make the app better—feel free to contact me directly at info@ardasen.com.
