Decibel X: dB, dBA Noise Meter App

"Decibel X" is one of very few noise meter apps on the market that has highly reliable, pre-calibrated measurements and supports dBA, dBC. It turns your iOS device into a professional sound level meter, precisely measures the sound pressure level (SPL) all around you. This extremely useful and beautiful tool will not only be a great tool for many uses but also bring you a lot of fun. Have you wondered how quiet is your room or how loud is a rock concert or sport event? "Decibel X" will help you answer all of those. WHAT MAKE IT GREAT AND STAND OUT FROM OTHER APPS: - Trusted accuracy: the app is tested and pre calibrated for all Apple devices. The precision is matching with real SPL devices - Apple Watch support: see noise level right from your wrist - Frequency weighting filters: ITU-R 468, A, B, C, Z - Powerful, smart history data management: + Recording data can be saved into a list of history records for future access and analysis + Each record can be exported as hi-res PNG graph or CSV text via sharing services + iCloud support which synchronize all history records across your Apple devices + Fullscreen mode to give overview the whole history of an record - Dosimeter with NIOSH, OSHA standards - FFT and BAR graphs to display real time FFT. Those are very useful for frequency analysis and musical tests. Real time predominant frequency is also displayed. - WAVE graph with 2 display modes: Rolling & Buffer - InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.). - Support both Portrait and Landscape layouts - Beautiful, intuitive and carefully crafted UI design - Optimized for iOS 11 OTHER GREAT FEATURES: - Standard time weightings (Response Time): SLOW (500 milliseconds) and FAST (200 milliseconds) - Trimming calibration from -15 dB to 15 dB - Standard measurement range from 30 dBA up to 130 dBA - HISTO graph for plotted history of the recorded values - Real time scale level chart - Display Current, Average/Leq, and Max values with both nice and clear digital and analog layouts - Quick reference text to help you compare with real-life examples - "Keep Device Stay Awake" option for long duration recording - Reset and clear current recording at any time - Tap on Max value to reset at any time - Pause/Resume the tool at any time NOTES: - Please do not expect a quiet room reading will be 0 dBA. The range 30-130 dBA is the standard usable range and an average quiet room will be about 30 dBA. - Although all devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. You will need a real external device or calibrated sound meter as a reference, then adjust the trimming calibration until the reading matches with the reference.

  • No way to unsubscribe 1/5

    By eitak noegdip
    The app gets you with “3 day free trial” but then offers no way to unsubscribe!! Very scammy. Do not download!!
  • Handy & helpful 4/5

    By Kent1861

  • Can you hear me now? 5/5

    By DrummerBoyLudwig
    I play in a club band and using this app is a great tool to see if we are playing too loud.
  • WAY TOO MANY ADS! 1/5

    By Knight Who Says "Ni!"
    This wonderful app has gone through a few too many “updates”... now ads pop every few seconds and the comparison scale is hidden away from the meter under the “Info” tab. This nice little utility when from a 5-star to a 1-star app in a matter of only a few months. This app used to be better. I can’t recommend it now.
  • Uhuh 1/5

    By Rapscallions
    You bug me for a review...you get one star.
  • Not clear how to cancel monthly payment 1/5

    By Thomas_loves_summit_meetings!

  • Review 5/5

    By colewestcott
    This is best review
  • Too many ads and push for upgrade 1/5

    By Surfskimmer
    App only worked for a day. After it would freeze and only worked for less than a minute after resetting. Also very irritating with the none stop push for upgrade. I understand you need to make money, but I will try and find something less pushy.
  • Bullcrud 1/5

    By Robrobiso
    Unsubscribe even possible?
  • Great app. Helps me daily. Recommend it to both Hearing and Hard if Hearing. 5/5

  • Unauthorized charges 1/5

    By Springtime987123
    I cancelled this app within the free trial period and yet they started charging my credit card with an auto renewal.
  • Bug in new versions 3/5

    By Wile E. C.
    The ad is blocking the noise level panel. Fix that please.
  • Steve M 5/5

    By SteveMiller
    Works exactly as it should.
  • Church is too loud 💥 5/5

    By not a cowboy

  • Project superintendent 5/5

    By nitronaminbomb
    Awesome I use this at work to keep my guys safe.
  • Too much money 2/5

    By Kenrus60
    As advertised this app can do a lot of things. Unfortunately you have to pay a lot of extra money to access about 3/4 of them.
  • Ads blocked the result on top 1/5

    By TITO THE COOL GUY
    I couldn’t see the results anymore on top
  • EXCELLENT!!! 5/5

    By BuzzCap7
    Fast ‘n easy to use. Love it!
  • Difficult to Unsubscribe! 1/5

    By Tgfghu
    It's a nice app, but only three free days. Not sure if they could provide a free version with advertisements. Not clear on how to unsubscribe. It's made clrar and easy to subscribe, but they make it difficult to unsubscribe. That my friends is the hook! Looking in the settings menu, there doesn't appear to be a clear unsubscribe button.
  • Nice app glad it’s fixed. 5/5

    By jon314159265
    Press “Restore Purchases” every time I want to use an app that I paid for, or agree to a subscription??? Just annoying. But it looks to be fixed now. So that’s good. Accuracy seems reasonable, and I actually like the unweighted option. Also helpful to confirm that my kid is super loud and my stereo isn’t, which validates my position in a long standing family debate.
  • Thanks for Fixing In-App Purchase Restoral Issue 5/5

    By ChocolutWunder
    As I have stated previously this SLM app is the best in breed! This is THE go to SLM app. Skypaw is not satisfied resting on their laurels and continue to rollout enhancements. Want to thank you personally for correcting purchase restore issue. Now I see my Modern Theme without ads like I am accustomed. Grateful. Onward and upward!
  • Canceling 1/5

    By Kev1013789)
    This is almost impossible to cancel. Don’t get the app.
  • Free trial? 1/5

    By wow123678
    How do I cancel my free trial? There are no buttons anywhere on the settings app about it. Very deceptive. And the “email support” button does nothing.
  • Whoa. 2/5

    By Won'tAcceptNegativeNames
    Too much garbage pops up when just trying to use the app. It would be much better if all the garbage extras were not continually pushed into the user’s face when trying to access just the decibel meter.
  • This is only a 3-day trial 1/5

    By AintBear1
    If it’s so great, tell me the price up front, not after I’ve already given your app access to my data and device. Sleazy.
  • Horrible. Not easy to cancel it 1/5

    By Leahwork777
    Trying to delete / cancel and literally can’t do it. Not in the settings. Not in iTunes. This should be illegal.
  • Useful and frequent updates 5/5

    By DunDano
    I have used the paid app for several years in restaurants and music venues to help control my exposure to harmful sound. The app is easy to use and informative. The app is frequently updated with features and themes. Version 7 cleaned up and enlarged everything with large fonts. I haven’t used the camera feature.
  • Beware of Sales CON 1/5

    By Stibbs186
    I bought the pro version of Decibel X. When I last started the app, I was FORCED to press a "try it for free button." On the next screen, in VERY small font and easy to miss, I found a button to "restore purchase". There should be a "restore purchase" button on the same screen as the "try it for free" screen. For that matter, there should not be a "restore purchase" button at all. This is clearly NOT user-friendly, and it seems that the company is attempting to CON subscribers for more money. Regardless of product quality, I will never purchase any of their products again.
  • What??? 1/5

    By Creasy_
    Why in the world would I want a “SUBSCRIPTION based” Spl meter??? Hell NO...
  • Not accurate 2/5

    By Ruff Ryder 800
    Not accurate. Measures 42 decibels in a quiet room.
  • Ok so far 4/5

    By xfdcghbytf
    Does what i need. Small enough use that i hope the authors get enough ad income from the ads i get when i switch functions. It has been hard to avoid hitting the free trial of the advanced button which i think cancels the really free ad version. If i get the project i need done two weeks from now with no annoyance i will come back and put 5 stars.
  • Owner 4/5

    By Dwight Leadbetter
    Very easy and accurate !!
  • Won't work anymore on iPod 1/5

    By Arbor lion

  • Great App 5/5

    By JRAYSIS
    Great !! Great !! Terrific App
  • Very handy 5/5

    By Honorable JJ
    If music is to loud just show readingand I always get there attention.
  • Not Happy 3/5

    By HobbySound
    I love this app and use it a lot. I paid for the “PRO” version and then they updated the app and now want me to pay another $8 for the app. Very uncool. How many times am I gonna have to pay for this app? Very frustrating!
  • No free version 1/5

    By evelyn7221
    Immediately after you download you have to agree to a 3 day trial and monthly iTunes billing before you can even use the app. Feels like a way to bait and switch people who just need a quick decibel reading into signing up for a service they’ll probably forget to cancel within three days.
  • "No Longer Compatible" 1/5

    By uranographer
    This app is no longer compatible with iOS 9. When you attempt to do the latest update, on iPod Touch 5th generation, it will tell you that. I contacted developer some days ago about the problem, since I purchased the app 2 or 3 years ago, but no reply or response of any kind.
  • Great app 5/5

    By deaf from truck noise
    Works for me. Trying to silence my diesel pick up. Easily Found areas I need to concentrate on. Easy to read while driving. Seems very sensitive to location
  • No longer works on iOS 9.3 1/5

    By Jimi0100
    Says works on iPad Pro 3, but update says it doesn't.
  • Crashes 3/5

    By hawtboi
    App crashes after a few seconds on my iPhone 6 Plus. Ok app otherwise.
  • Appreciation 5/5

    By Saeid Tayari
    Thanks a lot, you are doing a good job. I wish you more success.
  • Membership? 1/5

    By SupaP00
    So, this app may be good, but there doesn't seem to be a free version. It looks like a free, ad supported version is available, but when I opened it up for the first time, it wanted me to sign up for a free trial membership (3 days free). Now, is not to say I don't value a developer's time. I don't think I should get everything for free, but be up front about it.
  • Cannot cancel 1/5

    By CRS18
    There is no apparent way to cancel a forced subscription
  • Keeps crashing 1/5
