### 3/5 — Don’t spend money on this.

*2026-08-05*

First of all, it costs money after a few scans. Wasn’t excepting that for an app that doesn’t even let you delete a photo and retake it, is extremely blurry in the photos, and really just overall has a bad layout in the app.

### 4/5 — Needs to be quicker

*2026-06-26*

Needs an auto detecting centering so it’s a little quicker and easier to center to go thru more cards.

### 5/5 — Improved functionality over other card centering apps

*2025-12-26*

I would choose this app over competing apps every time. I'm actually shocked to see comments complaining about this being a "copycat" app when the functionality of this app over the "standard" is much better for several reasons. First, allowing users to manually rotate the image and adjust skewness is a game changer. Second, company grading standards are not locked behind a paywall, and instead update dynamically as centering is adjusted. Lastly, adding two control points per card edges promotes consistency. Future improvements I would love to see from this app are: 1) allow users to add data for the reverse side of a card after it's been saved, 2) reduce the size of the arrow icons for adjusting centering (and/or make them semi transparent), 3) provide an undo button to allow users to undo any accidental changes to the rotation or skewness of the image, and 4) allow users to toggle the company grading standards pane on and off so that users can avoid potential bias when modifying centering to meet certain grading standards. Thanks for this great app!

### 1/5 — Copy and worse version of original

*2025-06-25*

Just a copy of the original card centering app and these doesn’t perform nearly as well. On top of that the paid pricing is just absurd.

### 1/5 — A copy with a subscription

*2025-05-29*

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.

**Developer response:** 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.

This update is mostly about getting the measurement right the first time — and giving you the tools to fix it yourself when it isn't.

Detection

- Photos taken at an angle are straightened automatically
- Auto zoom and crop frame the card for you, so the guides are easy to reach
- Saved cards now use the same detection, so re-measuring one is as good as measuring a new photo

Editing
- Crop a photo, or undo every edit and get the original back
- Fix perspective by dragging a pin onto each corner, with a magnifier to place them exactly

Customization
- Style the guides your way — colours, line width, dashes, handle size, how many handles and where they sit
- Choose which grading standards appear throughout the app
- Turn auto detection, straightening, zoom and crop on or off to suit how you shoot
- Haptics, dark mode and camera level precision are all yours to set

Sharing
- Share a card as a slab-style image with its grades and measurements

Saved cards
- Rename and re-file cards, or swipe to edit from the list
- Re-measure, crop, share and adjust a saved card just like a new one

Camera

- Your camera settings are remembered for next time

Also
- Fixes for guide placement and measurement accuracy
