## What is Bubble Level + Compass?

Bubble Level + Compass combines a bubble level and a compass, with advanced controls for users who want more than the basics.

Use it to check horizontal/vertical/surface angles, or get compass direction relative to either true or magnetic north. For users who work with physical compasses, magnetic declination is also provided to convert magnetic readings to true north readings.

The level includes gyroscope calibration, which is especially useful on phones with a raised camera bump or an uneven back/case.

No nagging popups or interruptions. The free version only includes a small banner ad at the bottom.

Features
• Bullseye level plus horizontal and vertical levels with 0.1 degree precision.
• Compass with true north and magnetic north.
• Magnetic declination display for converting magnetic readings to true north readings.
• Gyroscope calibration for phones that do not rest perfectly flat.
• Gyro or accelerometer sensor mode.
• Clean interface with no popup interruptions.

If you enjoy the app, leaving a review would help.

An ad-free Pro version is also available, with more features including Apple Watch support, night mode, slope/inclination %, and pitch, yaw, and roll rotation rate.

## Key features

- Horizontal and vertical level measurements
- Surface angle readings

### 5/5 — Simple and Effective

*2026-04-15*

I love how simple this app is to use. It’s great at helping me with leveling things.

### 5/5 — Perfectly Simple

*2025-09-07*

Does what I need.  Very simple. Recommend.

### 5/5 — Just what I needed

*2025-01-15*

Amazing app which combines exactly what I needed to set up my telescope, thanks!

### 5/5 — Great product

*2024-04-18*

Great product

### 5/5 — Perfect for Positioning Solar Panels

*2024-01-10*

I finally found the app I was looking for!  When used with my Solar Angle Guide, this gives me the precise true azimuth, elevation, and time of the position of the sun. No pop-up ads, as advertised.

### 1/5 — Strange behavior

*2023-07-20*

If I align to north and rotate the phone precisely 180 degree the needle deviates 9 degree.
If I use two phones and align them, they also differ. HWplease

**Developer response:** The digital compass in a phone is not very accurate, as it is easily affected by local magnetic fields. If you are doing big movements with your arms holding your phone (see the help screen, "figure 8" movements are suggested) before each measurement and avoid placing the phone near metal/magnets, you should expect an accuracy of about +/- 2 degrees or so. At least that's what most users get with various iPhones - although from model to model they can be better or worse.
If you are consistently getting worse performance, make sure you don't have something like a magnetic clasp case etc. In any case, there's nothing "magic" an app can do to fix this, it is a hardware limitation of all phones.

### 5/5 — The best Caravan level

*2023-07-09*

This levelling app is the best and easiest I’ve tried. A bonus is the built in compass. I use it everyday when we are travelling with a caravan or car camping. Brilliant.

### 2/5 — Bubble Level

*2023-07-09*

Excellent utility; simple to use and effective.

**Developer response:** Hi. Thanks for the review. You seem to have liked it, are the only 2 stars by accident? Thanks

### 5/5 — The best.

*2023-06-15*

I use this for aligning my tripod for Astro photography. Can’t be beaten for features or price (FREE) highly recommended. *****

### 5/5 — Great app!

*2020-11-02*

I am a bit surprised as to how often I use this app. It always works, never glitches and easy and intuitive to use.

Thanks
