We've been selling mobile Chinese dictionary apps since 2001, and our sales and customer base have been steadily growing for 13 years across four different platforms. We take good care of our longtime users, too - people who bought the Oxford dictionary from us on a Palm Pilot in 2001 can still use that dictionary on their brand new Android phone in 2014 without even having to pay an upgrade fee. You can be confident that we'll still be fixing bugs and adding new features for many years to come.
Paid add-ons can be transferred to another device like any other paid app; load the free version of Pleco on your new device, go into "Add-ons" and tap "Restore Purchases."
If you already own Pleco on another OS, see pleco.com/android for upgrade / license transfer options.
