GTD Focus is an Omnifocus client for Android. Anyone who knows me knows how big of an Omnifocus user I am. In the past, in my failed attempts to switch platforms, a lack of presence from Omnifocus in Google Play has been the reason for a switch back to iOS. But, now with GTD Focus, that may be a thing of the past. If it works as advertised (and the majority of reviews say it does), then GTD Focus uses your Omnifocus server credentials to sync your data across platforms and directly onto your Android device. This is a Godsend. Android has been lacking in the task management app department on Google Play, but the tide is turning. If you are an Omnifocus user but use an Android device, for $4 and some change, check out this app. I think you will be pleasantly surprised.
