tripwolf celebrates the launching of its new universal app for Windows Phone 8.1 and Windows 8.1, and its optimised app for Android tablets by offering a free premium travel guide.
Install and start the tripwolf apps for Windows Phone 8.1, Windows 8.1, and Android, and select and download a premium travel guide for free on 3 April (US, 4 April in Australia) only.
I do not know how tripwolf keeps its purchase records because I got for free four different guides on four different devices (Windows Phone, Windows, Android phone & Android tablet; same Microsoft & Google accounts). However the app on each device cannot see that I have already "purchased" a guide on the other three devices.
There is also an app for iOS, but I cannot confirm if the deal is offered to Apple users since I do not own an iDevice.
On Windows Phone & Windows, guides for cities & regions cost $4.49 and for countries $6.99. On Android, guides generally cost more and have variable prices (typically $6.24 to $10.27).
Edit: One more free premium travel guide with coupon code piratesuk
thanks to TurnipHead and Holiday Pirates. Expiry 12 April US, 13 April Australia.
Unfortunately, the deal doesn't appear to apply to iOS app users (as implied in the description).
