  1. 5/5Best Free Level App I Could Find

    Im an amateur carpenter and couldn’t find my level one day when on a job. So I looked at, and downloaded, probably 6 different applications before I ended up downloading this one. This was the only one that did exactly what it said, and more, this app works perfectly, and it has many more useful tools then just a bubble level. My only issue is that it plays a commercial ever 5th or so times you change tools. But it’s free, and I understand nothing is really free in this world😂. One piece of advice I would give (this isn’t the apps fault) is your phone case, or in my case, my pop socket, has to be removed to get a real accurate reading. Otherwise great app for the money(free)has multiple styles of levels, and many other uses. Thanks for doing such a fine job making it!

  2. 1/5Why do I need to buy a subscription just to see if I’m hanging pictures level???

    This is the first time i have ever written a review for an app. That’s how upset this made me. For context, up until today I would have given this app 5 stars, maybe 4 because certain features aren’t super accurate. I’ve had this app installed on my phone for probably close to a decade by now, and it’s very handy for when i need a level. At first, it was only a few ads, and maybe a pop up telling you to upgrade to the better version, but today i go to hang a picture on my wall, and while im spending a reasonable amount of time leveling my picture, it gives me a screen that says “you’ve reached your limit!! please subscribe!!! and i can’t finish leveling my picture for another hour. For 5.99 a month, i could just go buy a level from the store. heck, i could buy a level every month until i have one in every room of my house. that sounds like a much better solution than paying some greedy company 6$ A MONTH just so i can use a basic tool.

  3. 5/5The most useful utility here!!

    I have been using this app for ages. Every major update is like a X-mas present. I know there is something great inside. I especially find the gyroscope to be extremely useful. I am a carpenter by trade and it seems like every time I take my table saw to a job site, I have to zero the blade with the table. I built a frame for my phone with magnets on the bottom and one side. Using the Gyroscope feature, I get a reading off the top of the saw, then attach the phone to the blade. When the gyroscope’s reading matches the top of the table, I know the blade is perfectly perpendicular to the table. Also, should I need to make a bevel cut, the gyroscope will give the perfect angle!! Many thanks and many more blessings!

  4. 5/5Very useful

    I find it is a well-made app with a lot of great features when I had gotten it I didn’t realize that my iPhone XS Max already had an app pre-programmed with a lot of the same features but not all of them I do like the visualization of the Bubble Level app compared to the iPhones factory installed version so I will be keeping it and I have gone ahead and paid to have the ads removed donate a dollar why not Would love to see more features Like a stud finder and improvements on the metal detector needs improved range as your phone has to be directly on the metal object in order to register and possible improvements throughout the app in the future but I will give it a definite five out of five

  5. 5/5Best set of tools on any device

    As I downloaded this app I was prepared to feel indifferent towards yet another e-tool application on the iPhone, after all very few e-tool apps have given me much to get excited about. But this set of tools is simply excellent, both in form and function. Between the clean intuitive interface and the quality build, you won’t find a better execution in any other app. Just stop, hit the download button and forget about all the rest, you’ve found the app you were looking (hoping) for.
