Hey everyone - as a bit of a hobby with learning to make Android apps, I had a go and produced an Android app to help level up pinballs when setting them up in a new location and I thought I would share it with everyone in case some people might find it useful. (I know someone made an iphone app that does similar) It works by the following:

(1)Placing your phone on the pinball and setting a profile
(2)Placing phone on pinball in new location and trying the centre the X - doing this achieves the set up in the old location.

OR

Press yPos (setting it off) to activate simple horizontal levelling with no need to calibrate to a machine. (You can still calibrate if needed to a flat surface with the set button)

You can turn on voice assistance (Using text to speech) so you can level up without looking at the phone - works for both modes.

You can get the app in the Google play store with the link below. The app is free and there are no adverts/IAP:

If you like please leave me some feedback or ideas for possible improvements - I will see what I can do! It would be nice if someone with a pinball machine could let me know if it is any good as I currently live in a shared house and no pinball to try it out with.

Thanks for the suggestion - what you want already exists although perhaps not obvious.

Press the yPos button to get a regular level (Horizontal direction only) which you will be able to use without setting it to a pinball machine.

EDIT: Altered main post to make it clearer.

I'll have a look at the code with the sensors to see if I can fix so it will work for more devices such as your tablet.

I'll also have a proper look at range and maybe make it setable by the user. Atm it some arbitary level that "felt about right" - probably some number of radians.

Had a look at the sensor code but I don't see anything wrong it so if it doesn't work then sorry I don't know how to fix it. (Least at the moment...)

Thanks for dl and feedback I appreciate it!

Working on an update and deciding to redo how profiles are done a bit. Instead of a list of profiles, instead there are a list of gradients which to match ranging from 4° to 8° in increments of 0.5°. You can add more values using the add button. To ensure these gradients can be matched properly there is a calibrate button to allow setting the horizontal and vertical tilt to zero when placed on a flat surface.

As for it not working I don't know why. I used the gravity sensor, maybe some devices don't support it for some reason. Might look into some other sensors as well - there is one for getting the rotation.

EDIT: Update released!
