I mean it works, but the video ads are... not good. I tried to level one shelf and had several videos ads pop up in the middle of it. Just use banner ads or have a single video ad, it's really not cool to spam ads. Just makes me want to try a different app that doesn't spam me. +5 stars cause it works great. -2 because of the ads.

When you pay to get rid of ads...... you still get ads. This is obviously an early attempt and I wish the Dev well, but this problem MUST be fixed. I'll give it a month, then I'm reporting to Google if not fixed.

The measurement is not precise/accurate. When I try to figure which part of the door cause a gap, it round up any side to 90 degree which doesn't make sense since it has a highly visible gap.
