Using Your Smartphone as a Digital Angle Gauge

Duration: 5:00

Setting angles on your tools can be a little tricky, and getting the angles just right is very important. If you’re doing something like stave construction, or any multi-sided item, being off just a few degrees on the set up can lead to disastrous results. But if you own a smart phone, the answer for accurately setting angles is at your fingertips.

Start with an App

Your phone on its own won’t be much help. You need to add an app that’s designed for reading angles. The app we’re using on an iPhone in this video is called Rotating Sphere Clinometer. If that specific app isn’t available for your device, there are lots of other angle reading apps out there. Get one for your phone.

Build a Jig

We need a very simple jig. The jig acts as a fixture that will hold your phone, and it also needs to have rare earth magnets on it that will secure the jig to your saw table and saw blade. Each jig will be a little different, depending on your phone, but some tips for making the jig are provided in the video.

Using Your Gauge

Once you’ve got the app and have built the jig, using your setup is easy. Zero the angle gauge to your table, then place the jig on your saw blade (with the saw unplugged) to determine the angle of the blade. Easy peezy.

Your Phone in Your Shop

There are a handful of helpful ways you can use your phone in the shop. Woodworking apps for your iPhone can definitely make your woodworking life easier.

      Dear John,

      Thank you for your patience. In response to your question-

      I haven’t tried a direct comparison, but a Wixey gauge is likely to be more accurate.

    THIS APP does not work on my Samsung galaxy 6. all i get is a frozen clinometer that is scale adjustable but does absolutely nothing else, I did find other apps that work, but they don’t give me the double-axis leveling action this one does. Just saying…waiting for a response from the app producer. Great idea though, I had no idea I could do this…could have used this type of app 100 times in the last 3 months.

    When are you going to start using captioning/subtitles on EVERYTHING? I saw a video here not too long ago that had the subtitles and was perfect, and then poof! I’m not the only woodworking deaf/hoh person that misses information.

    I was a gold member here a few years back. I had some medical issues and had to step back. My issues are now in remission and now, I”M BACK. Just downloaded this app, love it, just this one tip was worth the fee.
