I prefer that my apps give me seamless access to my data through either a web or Android interface. I also prefer apps that are multi-user aware for those things that need to be shared either with colleagues or family. To that end, I've found a few that do that well among the many that claim to do that:
- Cozi -- good shared shopping list with web access. It also has calendar, to-do lists, and journal features, but I don't use any of those.
- Evernote -- note-taking software with good syncing capability between Windows, web, and Android platforms. It has some sharing capabilities, but I have not tried to use any of them.
- Astrid and Producteev -- I use the combination of Astrid (Android app) and Producteev (web) for a shared task list. Astrid has the option of syncing with your Producteev shared task lists. You can also schedule time or reminders for a particular task on a Google calendar.
- Read It Later -- a great app that lets you mark blog posts, news articles, or other web pages for reading later. They have plugins for most web browsers so all your marked content is available on either Android or your web browser.
- Google Reader -- the Android version of Google's web-based RSS reader. Google's Android apps, as you would expect, are among the highest-quality apps out there. I really like how well the Android Reader app syncs the status of my read items with the web-based Reader app. I tried several other Android RSS apps and none of them did a good job syncing with Google's web-based Reader app.
The other thing that I would really like but have had much less success with is seamless file sharing with Windows 7 PCs. The built-in Connected Media app gets part of the way there, but I want something that allows me to seamlessly and wirelessly transfer files between Win7 and Android devices.
I've tried a couple apps that turn the Android into a web server with an interface for browsing and transferring files, but they all have significant drawbacks. I would like something an app that automatically makes my phone's filesystem accessible from Win7 over a wireless LAN without any additional actions on my part.
