Kept giving the same response
Response from developer
Thank you for your feedback. We're sorry about the repeated misidentifications when scanning the reverse side of your pennies and Roosevelt dimes. For better results, try using a plain, contrasting background with even lighting, and avoid glare or shadows that may obscure design details. We've flagged this pattern to our development team for investigation. If issues persist, please contact our support team directly so we can look into your specific scans. We appreciate your help in improving the app!

Serious collectors- AVOID
Response from developer
Thanks for the detailed feedback — points like these genuinely help us identify what needs work. We hear you on the inconsistencies you've described: the mint mark showing on one panel but appearing as N/A elsewhere, misidentifications on the American Women Quarters series, missing 2026 coin data, and previously scanned images appearing in place of new ones. These have all been logged and shared with our team to investigate and address. We're continually working to improve recognition accuracy, expand coin coverage, and tighten up the overall experience. Feedback from serious collectors is especially valuable in pushing those improvements forward, and we appreciate you taking the time to lay it out clearly.

Wrong Information and Value Amount.
Anyone opting to use this app with a subscription, beware. Those who have left a rating over one star is either paid to do so or is delusional. To the app maker,
Don’t bother responding with an excuse. Because I didn’t pay for it. If I had, that would be a different story.
Response from developer
Thank you for your feedback. We're sorry to hear the app did not meet your expectations. We take all feedback seriously and are continuously working to improve both accuracy and user experience. If you'd like to share any specific concerns, we'd be happy to look into them further.

My Opinion
No help
Works fine once you figure out the “bugs”
Original message: Downloaded app and took over 50 photos. App did not like any of the photos. Tried different lighting, different backgrounds, and different coins. Nothing worked. Canceled subscription (free trial) within 10 minutes.
Zero stars if that was an option.
Response from developer
Hi, we're truly sorry for the frustration. We’re currently refining our image recognition to better handle different lighting and backgrounds. We would love to make this right—please reach out to our support team so we can investigate why the app struggled with your specific device. Would you be open to sharing a sample photo with us to help improve our detection?

Wouldn’t stop asking me to write a review
Response from developer
Thank you for the feedback. We're sorry the review prompts appeared too frequently and too early in your experience. We've noted this and will pass it along to improve how and when these requests appear, so users have time to try the app first. We appreciate you giving it a try, and if there's anything we can help with as you use it, please reach out to our support team.

Poor functionality
Response from developer
Thank you for your feedback! We're pleased to let you know we've just released an update that addresses camera functionality issues.

Not good
Response from developer
Hi, we're sorry we couldn't identify your coin correctly. We know you put in real effort adjusting the lighting multiple times. Accuracy can also depend on the angle and coin condition. We're actively working on these issues and genuinely hope you'll give us another try down the road. Thanks for the feedback!
