Great news! Johny, a good friend of mine, who is a very skilled web programmer, has agreed to join the team and work on the mobile application. We had a meeting today, went through the specification so far and created a Github repository.
His estimate is to have the application finished within a month!
We are discussing the GUI in more detail. We came up with the idea of “Quick Bits” = 4 buttons that could be assigned different functions – like “+1 hour”, or “shift the next start by 1 hour”. The last one comes from my real experience, when my mother in law comes for visit; she sleeps in the room where the aquarium is. We want to let her sleep a bit longer, so I would want to simply shift the time when the lights turn on.
