Measure Angles - Bubble Level

I made a casual mistake of forgetting my protractor while trying to figure out the best angle for building my ramp extensions. I saw this app and after getting it calibrated, it made finding the best angle for the ramp height and length incredibly quick and easy. Thank you sir for creating an easy to use app. Also for those that get annoyed by a simple ad I highly recommend that you just go to the store and buy a protractor, the developer has the ad out of the way and it by no means restricts the controls or function of the app.

Just what I was liking for. Most clinometers require you to match the angle with the edge of the phone as you look at it. It’s also how mot handheld tool work. The problem is you have to be ON the slope and thus already in danger for that to work. In his excellent avalanche safety book, Bruce Tremper recommends using a mirror compass with a clinomètre that lets you sight downslope. The problem with that is the numbers are hard to read at arms length, are backwards and are off by whatever declination you have adjusted for which, in my area, is about 13 degrees. This app solves all those problems. You can use it on the slope sighting across, but you can also sight down a slope, double tap, and it saves the angle so you can read the number easily. Perfect for what I want.

So I’m an amateur astronomer. Your thinking ...why are you here. Well this app is amazing because it shares compass bearings and the inclinometer helps me find celestial objects in the night sky. I have my phone attached to my scope facing true north at 0 degrees inclination for calibration and I am able to swing my dobsonian telescope and angle it with reasonable accuracy. Usually within a degree or 2 in compass and inclination. While that’s a bit high error rate for more serious astronomers it works just fine for me to get a general sense of the target I’m searching for. My only recommendation from a purely selfish point of view is to have an option to show compass bearing on the same page as the inclinometer without having to switch between the 2 modes.
