I'm heavy user of Pebble and now N2. Pebble is most known smartwatch, because it allows others to create apps for it and marketplace is huge. http://www.fastcompa...what-comes-next
I'm aware of N2 SDK, but I think N2 should have something like miniapps. Apps that don't connect directly to smartpen, rather use N2 App to get some information.
Miniapps can be triggered by special symbol: ex. [!]
Use cases of miniapps
[!]calendar 10:30 tommorow at Starbucks -> atomatically add schedules to calendar
[!]play (staff & notes) -> note playing app starts playing notes in background
[!]wire $10 to brother -> banking app
[!]todo something todo -> todo app
[!]google something to google
[!]callme -> artificial call to get out of the meeting
[!]etc -> you get the point
From developer perspective:
Android App can make a broadcast and other apps just listen and receive written characters.
N2 App just looking for special symbol, then the rest of the drawings/characters broadcast to all apps
@Neolab If you like the idea, contact me, I'd like to help and create tutorial and boilerplace for miniapps.
