The vertical bubble disappears when I try to use it Useless
Horizontal mode Nice app the upright and surface mode works but the horizontal mode doesn't, my phone is an O+ 8.3 in the Philippines, please fix and i will rate 5 stars.
nice app nice one now I can play tilt games because it was calibrated.. tnx
OK but small flaws It works fine, the bubble is fairly responsive but... I have no problem with ads in apps but they sit right over one of the levels during 'plane mode' (holding your phone flat). Aesthetically the app is not the best laid out. Just a black screen with either one or two levels showing. Measuring using the phone in portrait mode (held upright) the animation is still in landscape mode although it is showing the correct reading.
Measures the wrong plane when I hold my device upright, rendering it useless.
2015 update, ensuring layout fits all modern devices.
