What is Reddit's opinion of Bubble level?

From 3.5 billion Reddit comments

I think you could just rig up a set of leveling blocks for your bed as low tech solution. Just use a bubble leveler there are even apps for that and stack short pieces of wood under the bed supports until it's level. Just need to make sure it's stable.

lol 60% grade.

Maybe 20 at best if you actually measured it. If you have android download this app called Bubble Level

This may work but I'm really unsure. I saw this question taking about calibrating a sensor. https://android.stackexchange.com/questions/59532/how-can-i-calibrate-the-tilting-sensor-on-android An app that was suggested is called bubble level and supposedly it can calibrate your sensor https://play.google.com/store/apps/details?id=net.androgames.level&hl=en Hope this helps

Recalibrate your gyroscope - If you on iphone, it's in your compass app, if you on android download a spirit level free app and hit calibrate while the phone is lying on a level flat surface.

This app: https://play.google.com/store/apps/details?id=net.androgames.level&hl=en

I don't own a Nexus 9, but is there a calibrate option in settings?

Edit: If you don't, you could try this app that iirc can calibrate the gyroscope: https://play.google.com/store/apps/details?id=net.androgames.level&hl=en

You can try this app to callibrate the accelerometer.
