The App

FishSpy Echo Pro

Bearded Hen were initially tasked with replicating our client’s Android version of the app as an iOS app but later took over the maintenance and upgrading of both Apps.

The apps connect to the buoys over a local WIFI connection using TCP/IP allowing the user to change buoy settings and stream both underwater video and sonar.

The main challenge encountered for this app was the need to process high volumes of sonar data in real-time to generate the on screen visualization of the sonar pings. Multiple optimization techniques were employed to achieve client targets.
