simple answer from Liine folks in the past is that they are not planning development for any platforms other than iOS. So, no Android, no Windows, no other UNIX variants.

hélas !

Citation de Liine :

Lemur is not available on Android but it is something we may consider doing in the future. It's always good to know what users want and what devices they are using.

Lemur Android

Lemur, the world’s best MIDI/OSC controller app, is now available for Android. Release includes recent fixes and feature updates. App available now on Google Play.

New Beginnings
Ten years ago, a company from Bordeaux going by the name of JazzMutant, released a revolutionary device — a multitouch screen for music control. To celebrate Lemur’s 10th birthday, Liine is proud to present Lemur on an entirely new platform. As the Lemur family spreads from the original hardware tablet, to iOS, and now Android too, music control is accessible to a new generation of passionate users.

Compatibility
Android is a vast platform and Liine had to choose which devices to support from the very beginning. Lemur is officially supported on Nexus 7 - this means that if you buy it for this device, Liine are committed to getting you up and running. It has also been tested on various Android 4.2+ devices with positive results. The list of officially supported devices will grow in the near future.
