As you can buy a nice Android tablet for 30 EUR – compared to 10 times or so for the cost the cheapest Ipad we focus our developments on Android. Android is also used on 87 % of the worlds’ smartphones (02-2020)

An Ipad – actually any IOS (and Mac) can be used to handle our solution on the web and to show / stream result (like any browser)

Another reason is – we have observed users prefer not to share their personal Ipad / iPhone to register details of the game but prefer to be able to register the game details on a separate shared device – hereby no private details and/or private notifications are being shown to everybody while you play bridge.
