In the FWIW (for what its worth) category.....
Over the years I have downloaded various apps that utilize the various sensors embedded in smart phones (e.g. sound meters, accelerometer meter, vibration meter, pressure, etc.).
As most of you, I rely on calibrated systems to do my business work; but I decided to check out a few and see how well they compare to calibrated systems.
As an example, I used my Vibration Meter app to compare to my calibrated sensors and to my surprise, they compared fairly well for lower frequency data (i.e. my grinder), particularly in the frequency values (My phone is usually protected with a plastic/rubber case so I took it off for some data). 
I have a small home-built rotor kit and used the 4 point no-phase to balance method to successfully balance the rotor.

Then today, I downloaded a free sound analyzer and compared it to test tones from my PC speakers -->  Frequency readout right on the button [smile]   

There was no intent on my part to do a detailed study ---  just curiosity; but surprise  pretty good data.

Not sure if anyone else has used similar smart phone apps as a "back-up better-than-nothing" sensor but I will be sure to keep these apps in mind.

If you have any apps you think are valuable, I would be interested to know

Hi Jim, Not quite a vibration related App but I live by Evernote to do my note taking on my routes and can record sound files I can then use as WAV files to post process for 'funny sounds' and other anomalies I might observe when on site.

It has powerful picture annotation and even presents the data you collect (kinda like powerpoint) if you so need to do so. The main perk is I use my iPhone 5s with me on routes and all my pics of stuff that I want to collect and any notes I add to Evernote, Then when I go to my iPad after the route I can show stuff to the customer before I leave the site if anything needs immediate attention.
When I am back at my office reporting I simply open my laptop and the desktop version has all the data I collected  (all synched in the background)   I have also set up visual inspection templates which evernote keeps for me.
 Also has a web interface so if I am on a customers terminal with web access I can look something up. 
It costs me about €5 per month and I think its well worth it.

So you're up to date on the 2140 but not your phone. There is elegance in simplicity and not the ongoing thing with keeping up to date. - constantly.  My wifes imac pro recently crashed because the latest ios update wasn't really comaptible anymore spent nearly 5 grand and 5 years old.) and had to be reset to older ios. $500 later.  And of course said wife say can you help.   off course I try but as an  engineer apple doesn't make sense. And I now refuse to deal with apple.  It  does not run my special even in ms environment mode, (think CSI) Because of special security devices for which there are no apple drivers.  Please trust me I am no idiot.  

So I am thinking Nok. Can I come to Bathurst and help you with your cattle?  Must be easier to stick arm up cow and bring a calf to life. than dealing with the changes we are faced with every day in the IT arena.

I´m on the android side, I use a lot Google Keep specially doing "inspections" and taking photos with hand writing annotations it's good enough to be "free"

also for the android users, try "footej camera" it has allways on flash function its great

I did a few tests on some apps. The ones I tested showed reasonable comparison, considering they are "toys".
