This (and many, many apps
) doesn't show up in my market either (Galaxy Nexus HSPA+, CM9/4.0.3 ROM, non-native dpi). Here is a workaround in ICS for almost all such apps:
(1) on your android device's browser, when you are NOT signed in to your google account in the browser, go to:
https://market.android.com/details?id=com.widgapp.NFC_ReTAG_FREE
(2) tap "install," bringing up a dialogue to select an app to continue the action
(3) select to continue with the browser, not the Market
(4) the browser will try to sign in automatically in ICS on the web sign in page, grant it permission to do so, which brings up another app selection dialogue
(5) this time, select the Market app
(6) you'll be greeted with the "not compatible" Market page. hit your "back" button
(7) you'll be back at the web sign in page. hit reload, bringing up the app-selection dialogue again.
(8) select the Market again
(9) this time, you should be able to download and install. once you select that, it will show incompatible again, but it will also show that it is downloading.
good luck!
This works with the San Francisco Bay Area transit card, the Clipper Card.
I would love a feature enabling/disabling GPS!
