The app still crashes on my iPhone 17 and IPad after restarting tried everything whenever I measure the height of something, could you please make a new app update? It still hasn’t been fixed yet.

Thank you for your feedback, and we’re sorry for the inconvenience. We understand that the app is crashing on both iPhone and iPad when measuring height. This is not the experience we want, and it may be related to device-specific AR processing or a bug in the measurement module. Please make sure you’re using the latest version of the app and restart your device. If the issue continues, contact our support team with your device models and iOS versions so we can investigate and fix it. Thanks for reporting this — it helps us improve stability.

Basically a sales tool.

Will do nothing except measure 5” without paying. Cannot even switch to metric.
The App world is dying due to the endless useless apps like this one.

Thank you for your feedback. We're sorry the app didn't meet your expectations. Could you please let us know which phone model you're using? This information will help us investigate the issue. We appreciate your comments and are always looking for ways to improve the app and user experience.

Mostly ok

Simple basic app. Displays inches and cm scales. Nice basic caliper usage too and bonus spirit level. But no clue how to use AR mode. Camera on, screen shows green grids and nothing more. No save or print ability. Unable to select objects. Unable to back out of AR mode.
Using iphone 15 pro max with os 26.5.

Thank you for your feedback, and we’re sorry for the confusion and inconvenience. We understand the issue with AR mode not responding as expected, including the inability to select objects or exit properly. This may be related to device compatibility, ARKit initialization, or a UI control issue on certain iOS versions. We also appreciate your suggestions regarding save/print functionality and improving usability. These are valuable improvements and will be considered for future updates. Please ensure you are using the latest version of the app, and if the issue persists, contact support with your device details so we can investigate further.

Thank you for your feedback! The option to switch to cm is available via the button under the display. We hope this helps!

Downloaded, opened, and problems

I have very little knowledge of this app other than what is said in the other reviews. I wanted to test it and did. 3 out of 5 stars bc when I went to measure a surface, it did not allow me to pick the right point. Apps should work right out of the Store.
