### 5/5 — Very useful for vehicle camping

*2026-03-24*

This is the best application that I have used for quickly leveling a vehicle in two dimensions when camping.

### 1/5 — Terrible

*2022-11-19*

Its the most useless app ever!!

### 2/5 — Pretty useless

*2022-10-18*

I went through a bunch of these to see if any were better than eyeballing it. Quick answer, no. Tried to use it to level a stove. First your case will mess it up. Even without a case, it indicated level when I can see it’s not. No surprise as the others were the same.

### 3/5 — Not precise enough for me

*2022-01-22*

Only displays to whole numbers.  I need .1 degree display.  Works well if you don’t mind being off by up to .5 degrees.

### 3/5 — Pictures don’t have gps location

*2021-03-21*

This is a nice app, but sadly I’m still searching for a better one. I use this type of tool to measure slopes every day. It’s great that I can take a picture of what I’m measuring with the slope bar superimposed over the image and save to my photos (with permission of course). But it fails in the the gps location is not encoded with the photo so that I can then do a PLACE search in iPhoto to find this data later.

### 5/5 — Awesome

*2021-02-22*

I’ve never reviewed an app before but this works very smoothly with no problems. It has no adds, in app-purchases or anything. Awesome and very easy to use app.

### 2/5 — Cannot Calibrate

*2019-12-26*

The way this app is designed requires a completely flat surface to “calibrate” the app. However, all this truly does is zero the level. To calibrate is a multi-step procedure which involves taking a reading, then rotating the device 180 degrees and taking another reading, the device should then be able to calculate a true zero. However, the procedure used by this app will only read as level as the surface one zeros the app on. Yet there is no way to know if that surface truly is level.

### 2/5 — Does not support vertical / plumb use.

*2018-11-04*

Can not use in the vertical / plumb in any way, only horizontally and angles.

### 5/5 — Works great

*2018-07-10*

I have an Apple iPhone SE w/iOS 11.4. I tried another level app that I could not get to work. The add’s worked though. So, I tried this app.  It appears to work just fine and is really easy, like it should be. 😊

### 5/5 — Works great

*2018-06-06*

Like other reviewers said, it does one thing and it does it perfectly.
