Most Bible software assumes a laptop, a stable connection, and an expert nearby. Many of the churches we serve have none of those. They do have a phone. BT Servant meets them there. Teams can ask a question in their own language, get guidance from trusted biblical resources, and keep moving. People still review the answers, so the teaching stays sound.
That matters most where the need is greatest: communities that learn by listening, and churches that must work quietly because following Jesus is costly.
