Android / iPhone apps accessing offline SARTopo server

I tested SARTopo offline and I think it could be a great fit for our SAR organization. In the ideal configuration we would have Android and iPhone app users connect to our offline SARTopo map server over a local WiFi network, download tiled data and map objects from that machine, then head out into the field.

From my testing it appears that the Android app can only download online base layers, and can only access maps that have been synced online. Given how often we operate without internet connectivity this makes the mobile apps far less useful to us, as search management maps will not be synced until the operation is over and the SAR manager/s have internet access again.

Based on my limited understanding of how SARTopo works, and some potentially naive assumptions, I would expect that making 'server location' editable by the user, and defaulting this location to the standard online address, could support offline use.

Are there any plans for the Android / iPhone apps to be usable in an offline mode?

    At this time the app doesn't allow for alternate servers, there are a lot of reasons why and a huge number of engineering challenges to overcome. We suggest to all teams that they download offline data to their devices before they have missions.

    However the desktop application (server) does allow mobile devices to view the data via their browsers if setup as a server with wifi.

    We do understand the use case, but the engineering in question is complex and won't be in the very near future.
