User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:29.0) Gecko/20100101 Firefox/29.0 (Beta/Release)
Build ID: 20140104030204

Steps to reproduce:

1- Install Ruler app from the marketplace
2- Compare cm or inch to a real life ruler
3- That worked on fxos-1.2 and fxos-1.3
4- Broken in current git.

- reference bug:

Actual results:

I have tested this on Geeksphone Peak and Keon devices, and that's not working fine on any of those devices, so it's not a hidpi issue. This was forking fine in older version of fxos (1month ago afaik)

I went back all the way to the latest 1.1 and no matter what build I tested (1.2, 1.3, or 1.4) it was always off by the same amount as shown in the two attached pictures.

moving to backlog for product review. We've lived with this since at 1.1 so not sure why we'd block on this now.
blocking-b2g: 1.4? → backlog

Definitely not blocking but we can look at fixing on backlog.

Jason - Do you know if this is an issue with B2G or an issue with the ruler app?

It's an issue with the ruler app if it's present on 1.1.

Lisa, this looks to be an issue with a Marketplace app. Is there a place for app bugs in Bugzilla?
Flags: needinfo?(adora)
Clearing the backlog flag as this is an app issue and not an issue with B2G.
blocking-b2g: backlog → ---
3rd party app bugs can go under Tech Evan > Preinstalled B2G Apps.

The Ruler app is owned by Pancake, who reported this bug, so I'm not sure what else app review can do to resolve this issue.

Here's the source code of the ruler app:

Feel free to report the issue. But I don't understand why this is an issue in my app, because i'm using mozmm and the plain mozmm test fails.

I think that the app shouldnt be available for buggy versions of FxOS, but the marketplace can't determine the client FxOS version, so this is not possible.
