I think a couple good tools to add would be a decibel meter and a speedometer

The scale of the ruler is way off.

This toolbox was performing flawlessly until the barometric pressure portion of the app ceased functioning. The altimeter was working OK, but the actual measurement of barometric pressure stopped working. Very disappointed in that but all the other functions were great.

Handy!

Barometer no longer works still not working

This app is great. It’s the longest lasting app I’ve ever had.

I have been using this app for yeeeeaaaars and absolutely love it. Wether I am mountaineering or carpenteering it has what I need. I use the altimeter and compass quite a bit. Only thing is I wish the Barometer worked without signal! Thanks for a great app!

No instructions, only settings can be changed, doesn’t work, nothing on screen, waste of time.

Is it letting me do anythin

Good but for one exception; that is the RULER is inaccurate. One inch is off by an eighth, which is quite a bit. There doesn’t seem to be any way to readjust that ruler to correct it.
