## What is SeeLevel?

Measure angles and align objects viewed through the camera. SeeLevel also includes a distance/height estimation tool and traceable level.

With SeeLevel you can for example:
- Find the angle relative to the horizon (like a sextant)
- Get the vertical line to the ground (like a plumb)
- Estimate the tilt of objects in the distance
- Calculate the height of, or distance to, an object (Inclinometer). 
- The unit of the input and output distances are always the same so you can use any unit you wish (meter, feet, yards etc)
- Use it as a conventional level, independent of the camera
- Zoom in the measured object to improve accuracy
- If your device has a front camera you can use it to measure the level from the ground or use it as an inverted plumb.

USER FEEDBACK:


Simple, effective and finally offering a clinometer with percentage. Very good, I can recommend it.

Piwilari, France

It is easy to use and effective for many types of measurements (angle, height, distance). The interface is uncluttered and very clear. Good job.

Very good idea that works very well.

I work for satelite co. and this is 'bout the best visual inclinometer I've come across, and yes my boss does like it, especially on how close the accuracy is compared to a Suunto Tandem.
Top Tier, USA


NOTE: Requires a device with a camera. i.e. compatible with all iPhones, iPod Touch 4 and iPad 2.

## Key features

- Measure angles relative to horizon

### 1/5 — App is apparently abandoned

*2022-03-11*

I got SeeLevel a week ago. The inclinometer, for which I bought the app, does not work. The inclination always reads NAN, even after an apparently successful calibration. For you non-computer folks, NAN means not-a-number and indicates that the inclinometer, at least, is seriously broken. 

I emailed the app’s author through the link in the Apple App Store explaining the problem but it’s been a week with no reply. 

The app has not been updated in 4 years. I have an iPhone 12 running IOS 15.3 so maybe I shouldn’t be surprised the app doesn’t work. My bad for not suspecting this before I bought the app. If you run similar hardware or IOS version buying this app is like throwing your money in the street. 

If I get an app update that fixes the problem I’ll revisit this review.

### 5/5 — Great for backcountry ski

*2022-01-07*

App is fast, interface is simple. Aim and read the angle, just what you want for skiing.

### 1/5 — User guide is useless

*2021-03-23*

Not intuitive and user guide doesn’t help.

### 5/5 — Great app

*2020-03-11*

This is a well designed, simple to use app for estimating heights, finding elevation angles and the like. Very good value too.

### 5/5 — Excellent app for height estimating

*2020-01-28*

I got this to be able to measure tree height for a new hobby of finding champion trees. The cost of a good clinometer is a bit much for a hobbyist. I bought a tripod adapter for my iPhone, which is a necessity for accurate results. You can not accurate results trying to hand hold.  To verify the accuracy, I measured the ground to soffit height of the roof of my house which was exactly 26’9” using a Leica Distometer laser. This app measured it at 26.7’ which is basically equivalent( less than 1” difference) I used an iPhone 6s with a tripod about 30’ away from the house on sloping ground. It is simple to use, but not intuitive, so read the guide.

### 5/5 — Great app!

*2019-11-10*

I use the inclinometer frequently for hiking trail building and design.  Easier to use and sufficiently accurate for everything but actual transit required accuracy.  

The level functionality is outstanding!

### 5/5 — Excelente aplicativo

*2019-08-21*

Exatamente o que eu procurava!!!

### 1/5 — Okay for really short distances (couple of metres)

*2019-01-19*

You can’t zoom in and no cross hairs.  Would suggest decimal points for a degree.  I found it repeatedly out by about 30cm going to 4 poles around my swimming pool.  Useless in this instance.

### 5/5 — Muito útil

*2017-09-26*

Excelente app. Usarei pra medir a inclinação das pistas de Ski!

### 4/5 — Fulfills needs

*2017-09-25*

This app replaces a $200 clinometer fairly well. I have had a couple glitches, but all in all I am very satisfied
