Apparently IBM finally recognizes Google’s Android OS as a viable platform, good enough to create a Lotus Notes app for it. Windows Mobile, iPhone and Nokia’s Symbian S60 handsets already have their own version of IBM’s Lotus Notes Traveler.

According to ZDNet UK, IBM announced at its Lotusphere conference in Florida that they will release a secure Lotus Notes client for Android devices. The app will be free to download, but you’ll have to buy the Lotus Domino server software in order for the app to work.

The mail, calendar and contacts app will run on handsets with Android 2.0 and higher (sorry Android 1.6 and 1.5 users), and will be the second major secure email platform outed for Google’s free mobile OS. Back in December 2009, Good Technology launched an email client that isolates and encrypts sensitive data on Android-powered phones.

So far there’s no word from IBM on the specific features of Lotus Notes Traveler for Google’s open-sourced mobile OS or when the Android email app will be made available. Will you get it when it comes out? Let us know in the comments.
