Sail is an Indoor Positioning platform that enables mobile app developers to create indoor navigation, location analytics and personalisation services.
It's the only indoor positioning solution that allows you to sign up, configure, and download an app from the app store to evaluate the technology for free in a day.
It’s a new approach to indoor positioning, with a subscription-based pricing model, and no up-front commitment. There's a completely free tier for single-floorplan use cases.
It uses the latest developments in machine learning to constantly reconfigure the system, removing the need for any fingerprinting or calibration.
