Super easy and convenient. Spot on. Only limited by your phones flashlight brightness.

I think it is a very useful app to have. It works well and is fairly easy to use.

As expected, this fails for a quarter second when the iphone cannot supply a high enough current over a long enough period of time(around 3 seconds) to the flashlight. Also, ads pop up on this. There are other, better apps for this.

Strobe Light Tachometer is a good app for control flashlight, camera and the others devices. It's so easy to use and helpful. The tutorial videos is very detail and clearly. I like this app. Thanks to the developers.

I'm a mechanical engineer and I love this app. Used it for few motors who specs were unknown. Thanks for an awesome e app!

Accurate and very good for a free RPM meter instead of buying a new on if yours breaks. All the right info in one simple place. Exactly what I was looking for

Have used it to measure rpm on a few things. Extremely useful handy. For someone who works on obsolete mechanical and electro mechanical equipment this is a dream app
