iSticky Server is listening to your Arduino project

Let your Arduino project deliver realtime notes to your iPhone or Mac with our iSticky/Arduino library!

We introduce iSticky 1.0 for iOS and iSticky 4.0 for OS X, a Productivity app that stores user’s notes on iSticky’s Cloud server for easy access on multiple devices. The new release for iOS integrates with the OS X version, supports push notifications, allows users to create note lists, share lists with other users, specify list permissions, encrypt note lists, and send notes to other users.

iSticky lets users send an infinite number of sticky notes to themselves and others, providing a quick, real-time solution for sending important information like reminders, updates, directions, meeting times, dinner plans, meet-up changes, or any other individual or group note. iSticky provides a fast and organized way to send notes, at home, in school, on the road, or in the office.

iSticky is a great solution for:

• Teams: to create real-time to-do lists
• Companies with employees on the road: to give them the latest information or orders
• Colleagues: to send quick reminders instead of sending emails or sticking paper notes on desks
• Families: to send quick reminders, menus, honey-do lists, and other important information
