Can't change one of the number fields without in app purchase. On top of that, it wouldn't even operate the light at all on my 5s. Don't bother.

Major issues with accuracy. I was strobing about 2,000 rpm, changed it by only 10, but speed cut to about half... Other times drop 10 pulses and the speed increases drastically... Useless for me

This app is working very well for me. The iPhone strobe is not very powerful but is is still very useable. This app is very useful to me.

It is great tool. I found it handy and very instrumental. This is really an effective tool for professional engineers on the move. Simple to use and do rotational diagnosis.
