Appmuse

I think this is a great app. It does all I expect it to. I don't have any reference point, but I am happy. Easy to use.

Simple and easy to use- just like my trusty Radio Shack I have been using for years but always in my pocket- A must for AV professionals.

I'm only interested I relative levels (maintaining a consistent monitor level, for example). So this app rocks for me even if it is a number or two off. Great studio tool. Show more

I like this little app. It's pretty accurate for a phone.

Calibrated, it shows a reasonable degree of accuracy. It's all an iPhone app SPL needs to be. The graphics work well. Quite happy with it. Let's call it a good purchase. Show more

The db knob is way to touchy. A three point calibration would be beneficial, as it is not accurate at all. I calibrated it on my iPhone4 at 85db. At 115db it indicates 96 and at 45db it indicates 58. These test were done using a professionally calibrated meter. Show more

I just got an onkyo 308 a/v receiver and it doesn't have a built in mic. Looked at radio shack and a SPL meter was 50 bucks. Downloaded this and it works great. I calibrated my stero, works like a charm. As for the other review, put it in C weighting and it gets the bass volume. Seems to be very accurate... Overall, VERY useful for the price. Show more

I was hoping this meter would measure bass but it doesnt. Very dissapointed. But for .99 can't really complain. lol

Well I don't know how accurate it is. Seemed to max out at around 90db with internal mic. Don't have an external. One thing that is annoying is the round scale knob. It seems to be be very touchy and a pain to set it to a value. Running on 4g iPod touch. Show more
