### 1/5 — Predatory subscription model that signs you up for a whole year

*2026-06-15*

Just add a subscription for one month.. why am I signing up for a super short trial if I'm being sold a year!! Makes absolutely no sense and is built to collect money from people who see 30 days and not 3 days for the free trial

### 1/5 — Limited functionality for the price

*2026-05-25*

I was very disappointed. All this app does is have you put your finger or ring on the screen and you move a slider. It does not use a camera or provide accurate size.

**Developer response:** It sounds like you were expecting more from the app, and we truly appreciate your feedback. We're committed to providing a valuable tool, and it’s clear we didn’t meet your expectations regarding functionality and accuracy. Your insights are invaluable, and we’re taking them to heart. If you have more details about features you'd like to see or specific concerns, please reach out to our support team at hello@appcano.io. Thank you for sharing your thoughts, and we hope to help you find a solution that works for you!

### 5/5 — Works with iPhone 17

*2026-02-14*

Many other apps don’t give accurate sizing info for newer model phones

**Developer response:** It's awesome to hear that the app is providing accurate sizing info for your iPhone 17! 🎉 Thank you for sharing your experience with us! We’re here to help you find the perfect fit every time. If you have any more feedback or questions, feel free to reach out! 😊

### 5/5 — Ring

*2026-01-16*

It works really well and you don’t have to pay for it

**Developer response:** We appreciate your feedback! 😊 We're so happy to hear that you find it effective and free! Enjoy using it! 🎉

### 1/5 — Incorrect Finger Sizing

*2025-11-24, version 1.0.5*

In store finger is 9 (1/4) while this app shows 7. How is this possible? Absolutely garbage given it doesn’t do what it’s supposed to do

### 1/5 — Didn’t work

*2025-11-01*

The app didn’t work

**Developer response:** Hey there! It seems like you're facing some challenges with the app. We truly appreciate your feedback and would love to hear more about the specific issues you're encountering. Please reach out to our support team at hello@appcano.io so we can assist you better. Thank you for sharing!

### 5/5 — Accuracy and Easy

*2025-10-17*

So easy to put your ring on the circle and measure in seconds! Excellent!

**Developer response:** Thanks for your awesome feedback! 😊 We're so happy to hear that you found the measurement process quick and easy. Your support means a lot to us! If you have any more thoughts or suggestions, feel free to share. Keep enjoying the app! 🌟

### 4/5 — Why I Didn't Give 5 Stars

*2025-09-27*

The reason I didn't give five stars is, I would like to see the values update dynamically as I adjust the slider.

**Developer response:** Thanks for your feedback! 😊 We totally get that having dynamic updates while adjusting the slider would enhance your experience. Your insights mean a lot to us, and we're always looking for ways to improve! Stay tuned for future updates! 🌟

### 5/5 — Accurate and Fun

*2025-09-18*

Seems to be accurate. It’s much better than printing off paper, cutting it and wrapping it around your finger!  Plus you never know when someone might need to know your ring size.

**Developer response:** It's awesome to hear you find it both accurate and enjoyable! 🎉 We really appreciate your feedback on our tool being a handy alternative to the old paper method. Your support means a lot to us! Keep enjoying the experience! 😊

### 1/5 — Totally inaccurate

*2025-07-22, version 1.0.5*

I know my ring sizes and the estimates it gives for fingers is wildly wrong. Like not even close.
