Dear BEIKS visitor or customer, as you can see we are preparing to launch our suite of applications on the new Android platform from Google.
Most while most of the links on this page are still inactive, I assure you that they will be and we are working hard to make it sooner rather than later.

The first Android phone is the HTC G1 introduced by T-Mobile in the US. We loved it. For a company that has never released a mobile product or operating system before, it is flat out fantastic. Our most sincere congratulations to Google, the Android Team, the HTC team and to T-Mobile who has recognized a winner.
BEIKS is committed to releasing its full line of reference titles to Android, including the language dictionaries, travel phrase books, word puzzle games and more.
