I looked at 30 other free apps before committing on this one. Out of the 30, this was the ONLY one that did not need any permissions (seriously, why would an app like this need to read my call history??) This app worked perfectly to determine if my sit/stand desk was even. Since each desk leg can be raised or lowered separately, it can easily become lopsided so this app will come in handy again. PROS: its FREE, no permissions, no malware detected, no ads, there are 5 ways to calibrate CONS: None

Excellent tools and fantastic no ads. Very comprehensive displays and options. Super fast responses (I.e. immediate, continuous and very smooth). Same developer has many excellent apps, using same themes. Had to reinstall all my apps in new phone, luckily I had one developer to look to for many of them making it much easier for me. Being familiar with the apps makes it easy to 'carry on as usual' with the new phone.

Great app. Does exactly what it says it should and does it very well. For me, it needs one extra feature to get the 5th star - I'd like to see an audio option that, when selected, gives an indication as you approach and reach level. This would make it much easier to use in direct sunlight and in positions where it's difficult to see the screen
