Prepare can be used both via the Prepare app on the iPad and also on any unit with a browser and web access. In other words, you can of course use Prepare on for example Windows Surface, Google Nexus or any other tablet - it only has to be via our web access: https://web.firstagenda.com
Via this web access, you have the same options as on the iPad and the two user interfaces are very similar. There are some simple advantages to the iPad compared to the web, for example documents have a better readability.
So far, we have prioritised developing an app for iPads as this is the most popular tablet. We do however keep an eye on developments in the market.
