### 5/5 — Problem with calibration promptly solved

*2021-03-09*

Unbeknownst to me my iPhone 6s was in Zoom mode which caused the app to not be properly calibrated. Mike Melnikov contacted me to learn about the issue and quickly updated the app to solve the problem. Very much appreciated.

**Developer response:** Hi! Can you send me more details about your phone and iOS version along with a screen photo with a ruler to mike@cherry-design.ru? If the problem exists, I will of course fix it, but I don't see any problems on my iPhone.

Thanks for your reply, Terry! The issue with the wrong ring size under certain circumstances (when using the app with activated Zoomed Mode) has been fixed and an updated version of "Ring Sizer Pro" v1.15.0 is ready and available for download.
