User Reviews

Reviews are mixed. Pros include cm/inch measurement support, a water-level feature, privacy options, and free/test availability. Cons focus on accuracy problems, device-size scaling issues, missing usage guidance, inconsistent cm metric behavior, and difficulty selecting measurement points. Overall reliability appears inconsistent with a need for clearer instructions, better cross-device compatibility, and improved measurement accuracy.

Pros

Supports measurements in both centimeters and inches
Built-in water level/inclinometer feature
Provides a privacy option to not sell or share data
Appears free to download/test

Cons

Measurements are not accurate / off by a lot (consistently reported across reviews)
UI/scale issues across devices / not responsive to different phone sizes
Lack of in-app instructions or guidance on how to use the app
cm metric switch/update problems (not reliably functioning after updates)
Difficulty selecting correct measurement points / imprecise point placement

This is not an app for me

by Br*****, 2025-10-12

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.
