## What is Spirit Level X?

This spirit level app helps you to bring your work into level. The sound indicates when the app is running. When the sound changes the iPhone is in level, if it is calibrated correctly. You can turn the sound on / off. Use the calibrate buttons to calibrate your digital spirit level. Below the air bubble you can read the value of calibration for next time. The default button restores the values. 

Use the spirit level if you for example have to put up a shelf and have to mark where you have to drill hole number two. 

The app will function optimally when the iPhone is laying down.

## Key features

- Sound indicator for leveling

### 5/5 — When you cant see the spirit level this is handy

*2021-06-20*

I was looking for a way to know if surface was leveled, but I was underneath fixing it to the wall. This enabled me to make the holes to fix the mounting brackets without help. Kudos to the dev.

### 2/5 — Not accurate enough

*2020-07-17*

The sounds don’t give you enough feedback/ variation to know when you are close to an acceptable range of level. Seems like it’s either way off, within a huge range of being level, or dead naughts.

**Developer response:** Thanks for the feedback. Good point. Trying to enhance the responsivity. Regards Bo

### 5/5 — Best free product!

*2015-06-28*

Just downloaded this before I start drilling in screws to hang a big painting. Absolutely brilliant! Love the high pitch beeping which tells me when the levelling is spot on ^^
