So, I've updated the hammock hang calculator app for iOS and the Android version will be out soon (just working out some bugs with the variable screen sizes). The app features new artwork and a more streamlined interface with the addition of a clinometer!
The clinometer allows you to use your phone as a sort of "level", utilizing your phone's accelerometer. This gives you a "live" reading of the angle of your suspension and the associated forces, based on the settings in the app. You can also save the angle so you can input the angle you see directly into the settings.
You can see screenshots and get more info on my blog post.
This is a free update for anyone who already downloaded the app.
FULL DISCLOSURE: This is a paid app, but I do not receive any royalties or payments whatsoever for its sale. The deal I worked out with the developer gives them 100% of the royalties as a means to pay for the app development.
