I’m Arvid and I am one of the core developers of Quelea. I am toying with the idea of using my time over the summer for Quelea development, specifically for making the remote app(s) available for iPhone (as well as Android). However, I would need to cover my living expenses via sponsorship over the summer to do this (around 460 EUR a month).
If you feel like you or your church could help sponsor me this summer (June through to August), then that would be fantastic. If so then please send me an email (arvid at quelea dot org) or reply here so I can work out if it’s feasible!
