Jolla just revealed the UI for their Sailfish OS. To me, it is a Harmattan-Playbook OS hybrid. The UI brings with it a double tap to wake feature (based on the demo we saw on stage), swipe to exit apps, swipe up on homescreen for the launcher, swipe down for the status info (battery, carrier signal etc.) and much more!
The multitasking view is on the homescreen in a similar manner to Playbook OS, with the same sort of “cards” as BB10 and Harmattan. What is better though, is the fact these act like widgets. For the music player, you can swipe the square on your homescreen, and it will change tracks. Clearly this is the best multitasking experience seen on a smartphone. The “ambience” feature is cool. Simply choose an image and “create ambience”, for the color scheme of the device to adjust to the selected image.
There are two videos below, the first being the official presentation as posted by Jolla, with the second being from a Finnish site, which shows the demo on an N950.
Something to point out; from the event we saw a list of partners such as carriers like DNA, but also software companies like Opera. Myriad appeared on the screen too. Sound familiar? They were the company behind making one of the android compatibility layers for MeeGo. In case you think it is a different Myriad, the second video linked shows an Android icon, plus the Sailfish OS wiki QA page, mentions Android apps.
What do the Android app developers need to do get their apps run on Jolla devices / devices based on the Sailfish OS?
Many Android(TM) applications will run on Jolla devices unchanged (Android is a trademark of Google Inc.). If you want to take advantage of all UI and other features of Sailfish OS and make your applications fast, you can port your applications to native QT/QML. There are extensive guides available on how to do that.
I am definitely excited and pleased for the ex-Nokians who have achieved something remarkable in a relatively short time.
Update: Here is another demo on the N950, and is better in my opinion, this time being shown by Jolla’s Senior Designer, Jaakko Roppola.
