Pros and cons of ytools-flashlight,ruler,spirit level,protractor and sound level meter app for iPhone and iPad

ytools-flashlight,ruler,spirit level,protractor and sound level meter app good for

I really like the app, it has so many tools in one location and they work well
The main tool I use is the ruler- very accurate with my iPhone 6. I used to carry a little 10cm measuring tape in my wallet because I frequently need to estimate size, now that I have this app I dont need to carry the tape any more!
Every function does whats awaited. That is what I await from good software.
Very good app, replaced "Measures.app” with this one, because design much better, no useless images. Dear developer, could you add “teslameter” which can detect magnetic fields? Thanks!

Some bad moments

Finally a way to dim the the flashlight! That alone makes the app worth it
Very useful, indeed. noche graphics and the morse code option is a must
The level is off, and the decibel meter does absolutely nothing. As usual, with most of these idiot developers, there are no written instructions whatsoever.
Im not sure why people are complaining about the lack of instructions, the app is straightforward and simple. The morse code can be helpful if you are lost. Depending on your phone and case, the protractor and sound meter results will vary. Why do people expect so much out of a phone app? If they really need a professional reading, they should buy a specialized tool. The mobile phone app gives a great approximate value.
Get the incessant Did Not Update message every time I try. So Ive got a number one in a red circle next to my Apple Store icon, and no way to get rid of it.
A good set of tools, any of which could be a useful app unto themselves but to find these particular tools combined is unusual. Excellent!
