Common complaints
- ✗Missing tape measure feature (camera-based measurement), despite being promised in the name12% of mentions
«Where's the promised tape measure? The screen just shows a 16cm ruler. I got my hopes up thinking it would measure through the camera»
- ✗Calibration inaccuracy—discrepancies with a real ruler increase with distance16% of mentions
«Very poor. Calibrating with a ruler shows that the further from 5cm you go, the more the shift to the right. In other apps, if you hit 1cm, then 5cm and 10cm will also match.»
- ✗Ads block exit, confusing interface, hidden paid features12% of mentions
«Every 10 seconds an ad pops up that you can't turn off and you can't go back. It's unclear what's in the additional features—you won't know until you pay»
- ✗Zero mark invisible due to rounded screen edges12% of mentions
«Zero is placed right at the screen edge. The screens are rounded at the corners and you can't clearly draw an imaginary line from zero»
- ✗Incorrect area calculation (example: 9×5 = 45.04 instead of 45)4% of mentions
«Area calculation is wrong. For example, 9.00×5.00 s=45.04»
