application for smart device

Our client is an American watch company promoting a distinctive watch line.

The Problem

The client produced a concept of a truly innovative wrist watch for the consumer market. This watch assists users in saving and remembering the most noteworthy moments of their lives. The device
is equipped with an e-ink display and a special button to push when something significant occurs.
When a user pushes the button, the display records an event. Up to five events per month can be
recorded. A step-by-step image similar to an infographic is displayed to visualize the intensity of
user’s life for the month.

The watch operates with a smartphone; the events control and editing are performed by a mobile
application developed by First Line Software.


The Solution


The mobile application is powered by both the iOS and Android platforms and facilitates
interoperability between the watch and smartphone over BLE (Bluetooth Low Energy) protocol. The
app connects the user’s watch and smartphone to add and edit events, add photos, descriptions,
and geolocation, and finally, share events with other users.


A BLE Testing Suite production control system was developed as part of the project. The watches
are manufactured in China and the system implemented at the production site provides one
hundred percent testing of the products.


The Results

Our client products are being actively promoted to the American consumer market.


The Technological Stack 

  • iOS SDK, Objective-C, Android SDK, Java, REST, JSON
  • Server-side: Amazon WS, Java, PostgreSQL; BLE Testing Suite: Linux, QT, GPIB
  • Bluetooth 4.0 (Low Energy) with GATT profile
