Bubble Level, Spirit Level

Easy to use, easy to read. Deviation from level is only .1 degrees due to side buttons on the phone itself. Non-issue.

Excellent app. I was considering buying a digital inclinometer when I saw someone use an app like this on YouTube. I tried a few, and settled on this one... It really does everything I need. The only issue I found is not the fault of the app; the edge of my phone is slighty curved. I solved this by 3D printing a rectangular frame, and now everything is great. (I was considering buying the Pro version, but reviews suggest it needs an update, so I'll leave it for a while.)

Definitely better than going to the store, paying them your hard earned money, and not getting what you want. This uses the technology you already have to give solid angle measurements. As well as letting you reset what the too considers to be level. Everything you would get from the junk the store sells, right before you throw it in a drawer and loose it for several years. BTW, there were a few one-time-ads that lasted less than a minute total. TOTALLY WORTH IT.

Really nice. Simple to understand. Being able to switch between auto-mode and manual is great. Plus, it's more accurate than the analog device I currently use in my shop! Just make sure the bottom of the case was square and true to the phone inside and voila, a level that you'll always have at hand because it's your phone! ⭐⭐⭐⭐⭐⭐(6 stars) edit: I never realized how much I was eyeballing angles. This is brilliant!

This app is awesome! I love how accurate the ruler is, and that I can calibrate it to my phone's screen size. The level works great. No intrusive ads, only time they come up is when I want to unlock new features (which is fine by me, I'd rather watch a few ads than spend money on the pro version) and the extra features are absolutely worth it.

Interface is simple. Looks easy to use. Will compare with an actual leveller for accuracy.

A really great little app. Lots of options. You have to watch an ad one time to unlock certain festures but then you''re good to go. Much, much less disruptive than the usual steady stream of ads. The calibration tool is, IMO, leaps and bounds ahead of most of the competition. A big thank you to the dev.

I got this for the ruler only. There are much better level apps. Color scheme here lacks any art sense at all, which is odd because the promo thumbnail is a decent color combo. Ruler is difficult to see because any color on white should be darkish. But white itself is too bright. Better to use reverse colors. White, light cyan or pale green text over dark background (medium blue or darker (background) looks great. This looks kind of like an app that was thrown together during lunch break. Sorry.

Great it does exactly what i need it to do and that is to match the exact angle of degree of rafters beams and joices when im replacing them on houses and apartments thx

Very nice, dual mode for vertical and horizontal leveling with an added bonus of doubling as a ruler! Please make metric and imperial mode for the ruler and make it easier to turn off and on without going to the menu but that's just a suggestion, this is a great app as it stands!

Great app, although it depends on the state of the gyroscope of your phone, if it's not working correctly the app will give wrong measurements

Nothing intuitive with this app. I cannot decipher the rotating colors and wonder why sometimes they freeze in position with two degrees of angle to level showing. I can't calibr8 it with any degree of confidence because it gives no feedback when you complete the procedure and also results in an unerasable pop-up that either says reset or save- and it just lingers right there on the screen. And also extreme volume on ads and if the ad speaker is muted the setting is forgotten on the next ad and

This is an awesome spirit level. I thought of buying a digital angle finder, but are now using this app instead. I love the various ways it can operate with either a bubble, vertical line or horizontal line. Thanks, A++

Good one with no adverts unless you click on this one button, it is easy to use.

App seems to work well and is user friendly, although how would one actually get level or plumb when most - if not all of us - have volume keys, on/off, lock/unlock and the chance of additional buttons or keys on either sides of our phones... Thats what does my head in.. maybe you could make a hard button press 'lock' or restriction so we can press our phones hard up against an object and get a true reading?

Fits my phone really nice, looks and feels great. You can really see how well this app works and the experience using it is amazingly beautiful sleek and well balanced. Really looks like your gliding your way around places such as going in stores, parks and public areas. Great to use.

Poor user interface compared to clinometer, you have to use peripheral vision to have good measurements and that's only for 90 degree angles. Can use the numbers only to get the angle you're hunting for but then whats the purpose for the dual tone gauge, might as well use an app with numbers and that's it. No aesthetically pleasing.

If u need quick access to a level, this app is for u. I've had it on my phone for 2 yrs now and only just realized how powerful and complete it is. It's just as accurate as my digital levels & it's always just a reach away. It's a keeper!

Extremely simple, usable in all 3 axes, and seems accurate compared to actual bubble levels. Can be used with a broom handle to level stuff, and I even use it when offroading to have awareness of the lean angles of my truck over aggresive terrain.

Gave this app a full five stars due to its simplicity, accuracy and convenience. Phone is always with me and saves carrying a second device. Using it for hobbies but I'm sure it will come in handy for other chores. install was quick and ready to use.

I wanted something to level my camper. Ball park is close enough. Sometimes I like a little pitch, so the water for the air conditioner will drip from a desired corner. Knowing the required degrees, will help in a future setup.

Bad UX. Right as you pass some threshold while tilting it, the UI suddenly changes and you can no longer see the same angle. Very frustrating to use. While it looks pretty, save ypurself the trouble and choose another level app.

Yes I found the app via video on YouTube. I was trying to get the height of an airplane stuck in a tree and it gave me the angle I needed to get the height position and then measure out how far it was, it gave me the angle. I wish it had the ability to give the same angles while holding the phone so you can look at the screen and get the same angle as opposed to having the phone sideways that you have to sight down the edge of the phone and then move your head to look at the screen!!

Nice - very practical and functional app for measuring, leveling, and finding angles.

Very simple, highly intuitive app, ideal for Vietnam where the level and plumb line have not reached wide acceptance, nearly everything is eye-balled rather Tha measured and consequently slip-shod.. Just a little effort more and excellence results!

If you always carry a level with you there is no reason to get this app. It is accurate, but the reason a 4' level is so big is to get better accuracy. I only need this occasionally, but it easily exceeds my needs.
