Anyone using any of these apps for sharpening knives? Example pics? Two bucks versus 30 to 40 bucks-
family on a budget :D
 
can't say for sure, I've never seen these. I did just take a look and I'd guess that the real estate on the blade angle would not be enough to get a valid reading. I'm sure the "experts" will chime in to prove me wrong.
 
I come from the Apple side of things, and there is plenty of spatial resolution from the camera, and, of course, the gyroscope, along with software access. I'm guessing the android universe will be the same. hoping...
 
I have a free Android app called "Clinometer" that works as an angle finder. I have only used it so far to check the actual angles of my Sharpmaker rods.
 
I have used the angle finder on the Iphone 6. It's with the compass app. I find it to be accurate enough. You will need to account for the angle of the primary bevel to get a more precise reading. I prefer to use trig myself, how high the center of the spine is above the stone, and figure the angle that way.
 
i have used iLevel and Clinometer (free)
both seem to work as accurately as each other, but iLevel allows you to set target angles, for easy repeatability.

with the edge pro apex i will use a 600grit stone and sharpie to match the existing bevel, then remove the knife, lay the stone on the table edge and set the target angle.
when i change stones i lay it on the table, adjust to hit the target angle, then continue with sharpening.

Thank you for responding everyone. It appears that angle finder apps have been discovered and useful for sharpening. I did a global search on the exact term <"angle finder app">, on blade forums, and found the following users referencing these apps:
nick_30, gusto5, Cereal_killer, uofaengr, stitchawl, shotgunner, bodog, bearfacedkiller, and bflying.
Folks don't give a lot of details which suggests that the apps usage is self evident, which is a long way from taking a year-long class to learn to use word processing software on a CPM computer :-() A number of free apps were referenced along with the need to sometimes try a couple different apps to meet our edge sharpening needs. Gearheads are inextricably drawn to tools, so it is not an either or question when someone discovers magnetic angle cubes and these apps. Both tools bring unique trigonometric based solutions to the user.

This is "clinometer + bubble level" by plaincode, sitting on sharpmaker fine stones at 40 degrees (or 20 dps). The 0.2 is likely from my desk being not entirely level itself where i set it up to take a picture. If your desk is really not level (and you get 18 and 22 for instance) you may want to find a more level area of your desk if sharpmaker is your tool of choice.

image not showing? maybe post it on free image site and give us the url. Very interested.
Read all four pages of post:
http://www.bladeforums.com/forums/showthread.php/1339022-angles-on-clamp-style-devices
and it is pretty clear that tenths of 1° are well within good enough to make an edge screaming sharp.

You are correct, a tenth of a degree should not be an issue. However as the sharpmaker is not a clamp system and thus the hand is independent from the sharpening stone, I was merely pointing out to be aware of the angles are too different, such as 2 full degrees, or even more. Picture should work now.
 
Thank you for posting the image gusto5; Peter offers the same application for both Android and iOS devices. We will need an app like this to establish angles with our homemade hybrid / mashup guided system using ideas from folks like Moxy and others on bladeforums, the web and professionals like Clay from Wickededge, Ron from KME, and Ben from EdgePro. It will be a great project for my boys and I, plus, it will provide the support necessary for my 12-year-old until he grows into enough fine motor skill that he can maintain verticality with both sharpmaker stones:

I am using the same app that was on the pic of the iphone. It seems pretty good as I am waiting on my cube to come in. You just have to make sure your foundation is flat like with all the rest of the devices

Hahaha, wax on, wax off to your boy!
 
I've used ileveler as a double check when I built my own version of the adjustable sharpening wedge. I used trigonometry to get initial angles and then used the app to check myself. I may have used the app for some "in between" angles too, but I can't remember.

However, the shape of a phone's sides, plus the cases that almost everyone uses, makes using these apps problematic in my opinion. If you really care about being exact and you can't use math to do it, I would use a "real" inclinometer like an Angle Cube or something similar. For all practical purposes none of this probably matters anyway.

Oh and just for fun, here's the original sharpening wedge that inspired me to make one. This is NOT my video. It's the video that inspired me:

Thanks for the link to the video, would you mind posting the picture of your device? I may want to make one some day.

I'll have to see if I can find it. I think I might know where it is. I haven't touched it since maybe a year after I built it. It was fun to mess with, but not as fun to use. Also, have you noticed that sometimes you watch youtube videos and someone makes something really nice and promises that you can make it too? Then you get 3 minutes into the video and realize they have a full shop of specialized equipment (jointer, planer, milling machine, drill press, etc).

I don't want to be that guy, but it kinda applies in this case. When I built this, I worked for a place that owned a CNC router. I had the guys design the piece in CAD and then cut the pieces, including a nice precise 3/8" deep channel, using the CNC machine. So what I have is kinda neat. But it's also unfinished and was built with a CNC machine, which probably makes it impractical to duplicate. Anyway, I'll post something if I can locate it.

Wow, that must be really neat! Thank you and look forward to that!
 
Found it. I'm not too proud of this creation but here it is. Also, I really have to give something like 95% credit to my coworkers for building this. I had the idea for the basics, but they laid it out in CAD, sized it, and then cut and built it for me. I was going to build it out of hardwood once we had a good design, but it kinda fizzled out. This is a one off prototype.
