Two versions of install badge. http://clients.fusecollective.com/flex/flex_sdk_builder_badge_v1.jpg http://clients.fusecollective.com/flex/flex_sdk_builder_badge_v2.jpg
V1 is consistent with look of the app so it's my recommendation to use that one. Let me know how you want assets and I'll attach them to JIRA. If you want to use one of the badge makers (or use template) it will look fine too. From what I can tell they will have different install button and bigger dark stroke. I can prepare 300x300 png without install button and stroke so you can use it as bg.
